Description

Soot blower system and method of control

The present invention relates to a soot blower control system, and more specifically, to divide the inside of the combustor into a plurality of compartments to calculate the soot removal conditions according to the temperature detected in each compartment, and after the economic evaluation according to the calculated soot removal conditions It relates to a soot blower system that can control the blower to inject steam and additives and a control method thereof.

Soot may occur inside the combustor during thermal power generation or when the boiler is running. The soot is produced by incomplete combustion of a fuel containing carbon and is attached to the surface of a heat exchange tube which is suspended as particulates in the combustion gas or located inside the combustor or on the wall inside the combustor. In addition, when a sticky component is included in the ash in the fuel, the ash is frequently melted and adhered to the surface of the heat exchanging tube at high temperature during combustion (slag, slagging), even if not melted boiler convection On the other hand, these components are tacky and often cause fouling on the tube surface. In the present specification, all of these phenomena are collectively called a soot.

When the soot is generated and present inside the combustor, the heat exchange efficiency of heat generated during combustion and the heat exchange fluid flowing inside the heat exchange piping is reduced. That is, since more fuel and combustion must be made to obtain the same heat amount, the combustion efficiency and economic efficiency at the time of soot generation can be reduced.

Accordingly, techniques for checking whether a suit is attached to a wall surface of a combustor or a surface of a heat exchange pipe located in the combustor have been introduced, and techniques for removing the same have been introduced.

Japanese Laid-Open Patent Publication No. 2014-510250 discloses a temperature sensing suit blower. Specifically, a sensor for sensing temperature is added to the soot blower to disclose a temperature sensing soot blower capable of measuring the temperature of the combustion gas, the lance tube and / or the cleaning fluid with a conventional soot blower function.

However, since this type of soot blower can only sense the temperature in the zone where the soot blower is located, there is a limitation that it is difficult to detect and immediately respond to the temperature of the zone where the soot blower cannot reach inside the combustor. In addition, there is a limitation in that no consideration can be found on the difference between the benefits that can be obtained when the soot blower is operated and the benefits that can be obtained when the soot blower is not operated. In addition, in view of problems such as erosion of the tube due to the characteristics of the soot blower which removes the soot by physical force only, there is a limit to the control of the soot having a very strong adhesion. In recent years, as the fuels used in boilers are diversified, solving these problems becomes increasingly important.

Korean Patent Publication No. 10-0345501 discloses a thermodynamic modeling module of a boiler soot blower control system. In detail, the present invention discloses a thermodynamic modeling module of a boiler soot blower control system that calculates a pollution degree by comparing actual values with reference values of pollution degree determination elements in a boiler and determines the degree of contamination of the soot blower according to the calculated pollution degree.

However, since this type of soot blower control system is not able to calculate the pollution degree of a specific area inside the boiler, there is a limit that it is difficult to effectively control the soot blower according to the pollution degree of each area. In addition, it still includes the limitation that no consideration can be found on the differences between the economic benefits arising from the operation of the soot blower and the economic benefits arising from the non-operation of the soot blower.

This will be described later.

As will be described later, the soot blower system according to an embodiment of the present invention can control the soot blower 300 according to the location of the soot by partitioning the space inside the combustor 10 into a plurality of compartments 100. However, for more accurate calculation of the generation position of the soot, it is preferable that the soot blower 300 is disposed corresponding to the position of the partition unit 100.

6) Description of the injection method of the soot blower 300

Steam and additives injected from the soot blower 300 may be injected with sufficient injection pressure to reach the central portion of the inner space of the combustor 10. Specifically, the soot blower 300 is provided along the wall 12 of the combustor 10, which cannot reach the central portion of the inner space of the combustor 10 unless steam and additives are injected at a sufficient injection pressure.

In this case, even if it is calculated that the soot is generated in the center of the inner space of the combustor 10 through the process to be described later may occur a situation that can not remove the soot due to the steam and additives do not reach.

Therefore, the steam injection unit 310 and the additive injection unit 330 is preferably formed to provide a sufficient injection pressure to the steam and the additive to be injected.

The additive injected from the additive injector 330 may be provided in a liquid phase or a solid phase. In the illustrated embodiment, the steam and the additives are sprayed independently from the steam sprayer 310 and the additive sprayer 33, respectively.

More specifically, when steam is injected on the path from the steam injector 310 to the soot, the additive is injected on the path and the steam and the additive are mixed before reaching the soot.

The mixture of steam and additives reaches the soot to remove the soot. At this time, not only the soot is removed by the physical force transmitted by the injection, but also a chemical reaction occurs by the additive, so that the soot can be chemically removed, so that more effective soot removal is possible.

Furthermore, since the additive is mixed with steam to further increase the chemical reactivity with the soot, the soot can be removed more effectively than if the steam and the additive reached the soot, respectively.

Any one or more of the steam injected from the steam injection unit 310 and the additive injected from the additive injection unit 330 may be injected into any one or more of the plurality of partitions 100. This will be described later.

That is, even if a soot is generated, the soot blower 300 is not operated immediately, but the soot blower 300 is operated in a direction to obtain more economic benefits by comparing the economic gains obtained when the soot blower 300 is operated and non-operated. Blower system can be operated.

In order to achieve the above object, the control unit 500 is a thermal-material balance calculation module 510, suit information calculation module 520, suit position calculation module 530, soot removal protocol calculation module 540, economic calculation Module 550 and soot blower actuation module 560.

Hereinafter, the control unit 500 will be described in detail with reference to FIG. 4.

1) Description of the thermal-material resin calculation module 510

The thermal-material resin calculation module 510 calculates the thermal-material resin using the temperature sensed by the sensor unit 400.

In one embodiment, the thermo-material resin is a concept comprising a thermal resin and a material resin. The mass balance is the calculation of the exchange of matter between the system and the boundary by the entry and exit of the material in a process.

In addition, the thermal balance is in what form and system the heat and work supplied to the thermodynamic system of the boiler, power plant, etc. accumulate and work outside in accordance with the laws of thermodynamics in what process and how the rest of the heat is damaged To compute.

The temperature sensed by the sensor unit 400 is transferred to the heat-material resin calculation module 510, and the heat-material resin is calculated using the difference in temperature of each compartment 100.

In one embodiment, the sensor unit 400 measures any one or more of the temperature of the steam flowing inside the heat exchange pipe 200 and the temperature of the gas flowing outside the heat exchange pipe 200. Preferably, both the temperature of steam and the temperature of gas can be measured.

If the temperature difference between the temperature of the steam and the gas is not large, it may be determined that heat exchange is occurring well. In addition, in order for the heat exchange through the heat exchange pipe 200 to occur well, since no foreign matter is formed on the surface of the heat exchange pipe 200 or less, it may be determined that material exchange occurs smoothly.

On the other hand, if the temperature difference between the temperature of the steam and the gas is not large, it may be determined that heat exchange does not occur well. In addition, if heat exchange through the heat exchange pipe 200 does not occur well, since a large amount of foreign matter is formed on the surface of the heat exchange pipe 200, it can be determined that the material exchange is also not smooth.

However, the calculated heat-material resin value may vary depending on the position of the partition 100. For example, at the inlet side of the steam flowing in the heat exchange pipe 200, the temperature difference between the temperature of the steam and the gas may be large because it is just before the heat exchange or immediately after the heat exchange starts.

On the contrary, since the heat exchange has sufficiently occurred on the outlet side through which the steam flowing inside the heat exchange pipe 200 flows out, the temperature difference between the temperature of steam and the gas may be small.

Therefore, the heat-material resin calculation module 510 calculates a dirt factor by applying weights according to characteristics such as the position of each compartment 100 to the calculated heat-material resin value.

The method of calculating the contamination factor values can vary. In one embodiment, the lower the heat-material resin value, the higher the contamination factor value, and the higher the heat-material resin value, the lower the contamination factor value may be.

When the contamination factor value is calculated, the heat-material balance calculation module 510 compares it with a preset reference contamination factor value. At this time, the predetermined reference pollution factor value may be changed according to various factors such as the combustion situation and the type of fuel. In one embodiment, the reference contamination factor value may be calculated by the design of the combustor 10.

If the calculated contamination factor value is less than or equal to the reference contamination factor value, it is determined that impurities have occurred within an allowable limit, and the heat-material resin calculation module 510 uses the temperature detected by the sensor unit 400 to determine the heat-material resin. The value is calculated in real time, the contamination factor value is calculated using this, and the process of comparing with the reference contamination factor value is repeated.

If the calculated contamination factor value exceeds the reference contamination factor value, the impurity exceeds the allowable limit, and the thermal-material balance calculation module 510 calculates the calculated thermal-material balance value and the contamination factor value from the suit information calculation module. Forward to 520.

In another embodiment, the thermal-material resin calculation module 510 may pollute the portion through a temperature located between the maximum temperature and the minimum temperature by using the temperature of the steam and the temperature distribution of the gas detected by the sensor 400. You can also compute argument values.

All of the above processes are performed in real time. That is, temperature sensing in the sensor unit 400, thermal-material balance calculation and contamination factor calculation, and comparison between the calculated pollution factor value and the reference contamination factor value are performed in real time.

In addition, the heat-material balance calculation module 510 compares the calculated contamination factor value with a predetermined threshold contamination factor value. In this case, the predetermined threshold contamination factor value may be determined by reducing the lifespan of the combustor 10 and performing the combustion process inside the combustor 10 when the combustor 10 is operated while a soot is present in the space inside the combustor 10. It may be set in consideration of the degree of deterioration of the efficiency of performing the heat exchange process, and may be changed according to various factors such as the combustion situation and the type of fuel.

If the calculated contamination factor value is greater than or equal to the threshold contamination factor value, the soot blower 300 may be controlled to operate regardless of the result of the economic calculation module 550 to be described later. This will be described later.

2) Description of suit information calculation module 520

When the contamination factor value calculated by the thermal-material resin calculation module 510 exceeds the reference contamination factor value, it may be determined that a soot is generated in the space inside the combustor 10.

At this time, in order to effectively remove the generated suit, information about the suit, such as the composition of the suit, is required, and the suit information calculation module 520 calculates the suit information.

Specifically, the suit information calculation module 520 calculates the phase equilibrium of the fuel using the temperature sensed by each compartment 100, and whether the generated soot is generated, the viscosity of the soot, the composition of the soot, Calculate any one or more of the bond strengths of the suit.

To this end, the suit information calculation module 520 may further include a phase balance information database (not shown) that stores phase balance information according to the type and temperature of the injected fuel.

The suit information calculated by the suit information calculating module 520 is transferred to the suit removing protocol calculating module 540 which will be described later, and used to calculate an optimal protocol for removing the suit. This will be described later.

3) Description of suit position calculation module 530

When the contamination factor value calculated by the heat-material resin calculation module 510 exceeds a preset reference contamination factor value, it may be determined that a soot is generated in the space inside the combustor 10.

At this time, since it is necessary to determine which compartment 100 belongs to where the soot is generated, it is possible to control only the soot blower 300 so that the soot can be removed.

The soot position calculation module 530 calculates the partition unit 100 corresponding to the position of the sensor unit 400 that senses the temperature as a soot generating position. In this case, the position of the sensor unit 400 may indicate a position where the sensor unit 400 senses a temperature as well as a physical position.

As described above, the sensor unit 400 may sense the temperature of each part of the space inside the combustor 10 partitioned into the plurality of partition units 100, and the soot position calculation module 530 detects the temperature. The compartment 100 determined to have generated a soot in the compartment 100 is calculated as a soot generating position.

That is, the temperature of each compartment 100 sensed by the sensor unit 400, the suit information and the suit generation position calculated through the compartment unit 100 are mapped to the positions of the compartments 100 in the suit position calculation module 530. Stored.

The calculated suit generation position is transmitted to the suit removal protocol calculation module 540 which will be described later, and the suit removal protocol for removing the suit generated by operating the suit blower 300 assigned to the partition unit 100 is calculated. The process will be described later.

4) Description of Suit Removal Protocol Compute Module 540

The suit removal protocol calculation module 540 calculates an optimal protocol required for suit removal according to the suit information calculated by the suit information calculation module 520 and the suit position calculated by the suit position calculation module 530. Here, the 'protocol' encompasses all methods for performing the purpose under the input condition.

Specifically, the suit removal protocol calculation module 540 may include the suit information and the suit position calculation module 530 including any one or more of the viscosity of the suit, the composition of the suit, and the bond strength of the suit calculated by the suit information calculation module 520. Passed the suit position calculated in). Compute the best protocol to eliminate this.

The soot removal protocol calculated by the soot removal protocol calculation module 540 includes a flow rate of steam injected from the steam injection unit 310 of the soot blower 300, a pressure of steam, an injection angle of steam, and an additive injection unit 330. It may include any one or more of whether the injection of the additive to be injected, the type of the additive, the amount of the additive and the injection angle of the additive.

The soot removal protocol computed by the soot removal protocol calculation module 540 is passed to the economy calculation module 550 to determine whether or not it is economically desirable to perform the soot blower operation module 560. And is used as soot blower 300 control information for soot removal.

5) Description of Economics Computation Module 550

When a soot is generated in the space inside the combustor 10 during operation of the combustor 10, since the heat exchange efficiency and the combustion efficiency may decrease, it is common to proceed with removing the soot.

Since the additive is generally expensive, it may be undesirable in terms of economics if the soot blower 300 is operated every time a soot is generated to remove the soot by spraying both steam and additives.

In order to prevent this, there is a method of automatically operating the suit blower 300 at regular time intervals, but it is also difficult to remove the suit effectively and economically because the occurrence of the suit and characteristics of the suit are not reflected.

Therefore, while the soot blower 300 is controlled to operate only when a soot is generated, it is preferable to determine whether or not to proceed with the soot removal process by comparing the economic aspects of removing and not removing the soot.

The economic calculation module 550 converts the cost and the effects of the soot removal protocol calculated by the soot removal protocol calculation module 540 into economical gains, and compares the economical gains predicted when the soot removal is not performed. It is determined whether or not to perform the soot removal protocol.

Specifically, the economics calculation module 550 is a cost cost (cost) predicted according to the flow rate and steam pressure of the steam required to perform the calculated soot removal protocol, whether the additive is injected, the type of the additive and the amount of the additive To predict.

In addition, the economic calculation module 550 converts a combustion efficiency value (benefit) predicted to be improved when performing the soot removal protocol into a combustion profit value which is an economic index.

Combustion benefit values can be converted in several ways. For example, the combustion benefit value may include the cost of reducing the heat exchange amount or the heat exchange efficiency by removing the soot, thereby reducing fuel and oxidant inputs, and the like, according to the operation of the combustor 10 in which the soot is removed. It may further include costs associated with other benefits that may be obtained.

At this time, the combustion profit value corresponds to the gain obtained by performing the soot elimination protocol, and the consumption cost value corresponds to the loss for performing the soot elimination protocol. The term "performance benefit" is referred to below as the total economic benefit that can be obtained by performing the soot removal protocol.

In addition, the economic calculation module 550 calculates a combustion benefit value (hereinafter, referred to as "non-execution benefit value") predicted when the soot removal protocol is not performed.

Specifically, since the soot removal protocol is not performed, the consumption cost value is zero.

In addition, since the combustor 10 continues to operate even when the soot removal protocol is not performed, the combustor 10 may further include costs associated with other benefits that may be obtained under the combustor operation 10 with the soot present, such as heat exchange amount or heat exchange efficiency. have.

However, in this case, since the combustor 10 is operated in a state where a soot is generated in the space inside the combustor 10, the combustion profit value may be lower than that when the soot is not generated.

The economic calculation module 550 compares the calculated two values. That is, the performance benefit value predicted when performing the soot elimination protocol is compared with the performance benefit value predicted when the soot elimination protocol is not performed.

As a result of the comparison, when the performance benefit value is less than or equal to the performance benefit value, the economic calculation module 550 determines that the soot elimination protocol is not performed.

That is, when the performance benefit value is less than the performance benefit value, it is more profitable to operate the combustor 10 without leaving the suit, so that the suit blower 300 is not operated.

In addition, when the performance benefit value and the performance benefit value are the same, since the same profit can be obtained even without operating the soot blower 300, it is not necessary to operate the soot blower 300.

Thus, the economics computing module 550 passes control information to the soot blower operating module 560 that does not operate the soot blower 300.

If the performance benefit value exceeds the performance benefit value, it is more profitable to perform the soot removal protocol, so the economics computation module 550 sends control information to the soot blower operation module 560 to operate the soot blower 300. To pass.

6) Description of the soot blower operating module 560

The soot blower operation module 560 independently controls the steam injection unit 310 and the additive injection unit 330 of the soot blower 300 in real time.

When the suit information and the suit elimination protocol are calculated through the above-described processes, and the economic efficiency calculation module 550 determines that the suit elimination protocol is performed, the partition unit 100 in which the suit calculated by the suit position calculating module 530 is generated. Each of the pieces of information, including the information of the < RTI ID = 0.0 >

Specifically, the soot blower operation module 560 controls the soot blower 300 in correspondence with the soot removal protocol calculated by the soot removal protocol calculation module 540, so that the steam injection unit 310 and the additive injection unit 330 are controlled. Remove the soot by spraying steam and additives from the.

When the soot blower 300 has performed all of the calculated soot removal protocols, the soot blower activation module 560 stops the soot blower 300 from operating.

In addition, when it is determined that the economy calculation module 550 does not perform the soot removal protocol, the soot blower operation module 560 does not operate the soot blower 300, and the combustor 10 has a soot inside the space. Continue operation with formation.

However, when the contamination factor value calculated by the heat-material resin calculation module 510 is equal to or greater than the threshold contamination factor value, the soot blower operation module 560 may perform the soot removal protocol calculation module regardless of the calculation result of the economic calculation module 550. The soot blower 300 may be controlled according to the soot removal protocol calculated at 540. This will be described later.

2. Description of the control method of the soot blower system

Hereinafter, a control method of a soot blower system according to an exemplary embodiment of the present invention will be described with reference to FIG. 5. Descriptions of portions overlapping with the description of each module 510, 520, 530, 540, and 550 described above will be omitted.

(1) Description of the steps of the sensor unit 400 to detect the temperature

First, the sensor unit 400 detects at least one of a temperature of steam flowing inside the heat exchange pipe 200 and a temperature of a gas flowing outside the heat exchange pipe 200 in real time. At this time, for more accurate soot generation detection, it is preferable to detect both the temperature of the steam and the temperature of the gas.

In addition, the sensor unit 400 may detect a temperature of each partition unit 100 partitioning the space inside the combustor 10 into a plurality of spaces.

The temperature of each compartment 100 sensed by the sensor unit 400 is transmitted to the heat-material resin calculation module 510 and used to calculate the heat-material resin and the contamination factor value.

(2) Description of the step in which the heat-material balance calculation module 510 calculates the heat-material balance value and the contamination factor value

The heat-material resin calculation module 510 calculates the heat-material resin value of each compartment 100 in real time using the temperature of each compartment 100 sensed by the sensor unit 400, and calculates the calculated angles. The contamination factor value of each compartment 100 is calculated in real time using the heat-material resin value of the compartment 100.

 (3) Description of the step in which the heat-material resin calculation module 510 compares the calculated contamination factor value with the reference contamination factor value

When the contamination factor value of each compartment 100 is calculated, the heat-material balance calculation module 510 compares it with a preset reference contamination factor value in real time.

If the calculated contamination factor value is less than or equal to the reference factor value, it is determined that impurities have occurred within an allowable limit, and the thermal-material resin calculation module 510 uses the temperature detected by the sensor unit 400 to determine the thermal-material resin value. Is calculated in real time, the contamination factor value is calculated using this, and the process of comparing with the reference contamination factor value is repeated.

If the calculated contamination factor value exceeds the reference contamination factor value, the impurity exceeds the allowable limit, and the thermal-material balance calculation module 510 calculates the calculated thermal-material balance value and the contamination factor value from the suit information calculation module. Forward to 520.

(4) Description of the steps in which the suit information calculation module 520 calculates the suit information.

The suit information calculation module 520 calculates the phase equilibrium of the fuel by using the temperature sensed by the sensor unit 400, and whether or not the generated soot is generated, the viscosity of the soot, the composition of the soot, and the bond strength of the suit. Calculate any one or more of them in real time.

To this end, the suit information calculation module 520 may further include a phase balance information database (not shown) that stores phase balance information according to the type and temperature of the injected fuel.

(5) Description of the steps of the soot position calculation module 530 calculating the soot position.

The soot position calculation module 530 calculates the soot position in real time using the position of the assigned partition unit 100 corresponding to the position of the sensor unit 400 that senses the temperature.

Specifically, the soot position calculation module 530 has a contamination factor value calculated by the heat-material resin calculation module 510 among the plurality of compartments 100 in which the sensor unit 400 senses a temperature than a reference contamination factor value. The position of the partition portion 100 calculated as large is calculated as the soot position.

(6) Description of the steps in which the soot removal protocol calculation module 540 calculates the soot removal protocol.

The suit removal protocol calculation module 540 calculates the suit removal protocol in real time according to the suit information calculated by the suit composition calculation module 520 and the suit position calculated by the suit position calculation module 530.

Specifically, the soot removal protocol calculation module 540 may be configured to optimize the soot removal according to the location and composition of the soot generated, such as the flow rate of the steam injected from the steam injection unit 310 of the soot blower 300, the pressure of the steam, and additives. The type of the additive and the amount of the additive injected from the sand 330 are calculated.

(7) Description of the process of the economic calculation module 550 calculating economics

The economic calculation module 550 calculates the consumption cost value and the combustion efficiency value predicted when performing the calculated soot removal protocol, converts the calculated combustion efficiency value into the combustion profit value, and calculates the consumption cost calculated from the converted combustion profit value. Subtract the value.

Also, if the result of subtracting the calculated consumption cost value from the converted combustion profit value is less than the combustion profit value predicted when the calculated soot removal protocol is not performed, the soot blower 300 is not operated. To prevent it.

If the result of subtracting the calculated consumption cost value from the calculated combustion profit value exceeds the combustion profit value predicted when the calculated soot elimination protocol is not performed, the economic calculation module 550 causes the soot blower 300 to operate. To control.

(8) Description of the steps by the soot blower operating module 560 to control the soot blower 300

The soot blower operation module 560 controls the soot blower 300 in accordance with the calculated soot removal protocol.

More specifically, when the economics calculation module 550 calculates that it is economically beneficial to perform the calculated soot removal protocol, the soot blower operation module 560 is adapted to the soot blower 300 corresponding to the calculated soot removal protocol. Is operated to remove the soot formed in the space inside the combustor 10.

When the soot blower 300 has performed all of the calculated soot removal protocols, the soot blower activation module 560 stops the soot blower 300 from operating.

If the economic calculation module 550 calculates that performing the calculated soot removal protocol is economically detrimental, the soot blower operation module 560 does not perform the calculated soot removal protocol and does not perform the operation of the soot blower 300. Stop operation

(9) Economic Explanation of the case where the soot blower 300 is operated even when the economic efficiency calculated by the calculation module 550 is low.

As described above, the economic calculation module 550 calculates and compares the economics of performing the soot removal protocol calculated by the soot removal protocol calculation module 540 and the non-executing, respectively, and then obtains the economics that can be obtained when performing the soot removal protocol. Activate the soot blower 300 when the profit is high.

However, in certain situations, the soot blower 300 may need to be operated even when the economic efficiency calculated by the economic calculation module 550 is low for the life and stable operation of the combustor 10.

This is because if the generated soot is left as it is, the life of the combustor 10 may be shortened, and a combustion process and a heat exchange process performed in the combustor 10 may not be performed smoothly.

Therefore, even if some losses are predicted in terms of economics, a process of removing the suit is required, and a threshold contamination factor value may be set as a criterion for determining the need.

The critical contamination factor value may be set in consideration of the reduction of the life of the combustor 10 and the deterioration of the efficiency of performing the combustion process and the heat exchange process in the combustor 10 when the combustor 10 is operated as it is in a soot generation situation. Can be.

If the contamination factor value calculated by the heat-resin calculation module 510 is equal to or greater than the threshold contamination factor value, the soot blower operation module 560 may perform the soot removal protocol calculation module 540 regardless of the calculation result of the economic efficiency calculation module 550. The soot blower 300 is controlled according to the soot removal protocol calculated in to remove soot formed in the space inside the combustor 10.

Of course, when the contamination factor value calculated by the heat-resin calculation module 510 is less than the threshold contamination factor value, it may be determined whether the soot blower 300 is operated according to the calculation result of the economic efficiency calculation module 550.

In the soot blower system according to an embodiment of the present invention, the space inside the combustor 10 is partitioned into a plurality of compartments 100, and the temperature of each compartment 100 is sensed through the sensor unit 400. Since it is determined whether the soot is generated by calculating the heat-material resin value and the contamination factor value by using the sensed temperature, the soot blower 300 may be operated only when the soot is generated, thereby eliminating the soot. It is possible to reduce the loss caused by the operation of 300).

In addition, it is possible to predict the viscosity, composition, adhesion strength, etc. of the soot by using the heat-material balance value and the contaminant factor value, and to calculate the soot removal protocol accordingly. This allows for effective removal of the suit.

Furthermore, even when the suit elimination protocol is calculated, the suit blower 300 is operated by judging the economic feasibility of performing or not performing the suit elimination protocol calculated through economic calculation, so that the loss compared to the profit obtained when removing the suit. In large cases, the soot removal protocol may not be performed, thereby maximizing the economic benefits of operating the combustor 10.

Although it has been described above with reference to preferred embodiments of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the invention described in the claims below.
