Technical field
The coal that the present invention relates to more than one coals is the progress control method and the boiler run control system of the boiler of fuel.
Background technology
Because the coal burning boiler (with the boiler of coal) that usually in the power plant, the uses coal from import all over the world commonly used, so it is also various to be used in the character (coal character) of the coal in the boiler as raw material.Because combustion characteristics changes because of the difference of coal character, be the operation that is adapted to different coals so improve the important indicator of boiler efficiency again.
Therefore, all the time, the operation of manual many coals of the reply boiler by operator control or tackle the operation control of many coals boiler by computer.The former is following method: the operator utilizes empirical index to judge the kind of coal, set coal (caloric value of this coal, fuel ratio, moisture, ash content, comminuted etc.) in the operational parameter control calculation procedure of bonded boiler operating control device, control CALCULATION OF PARAMETERS as required, and control the adjustment of parameter as required.
The latter is following method: the ash behind the analysis coal combustion etc., infer the coal character of multiple coal, based on this coal character, control CALCULATION OF PARAMETERS with the operational parameter control calculation procedure, and this result of calculation outputed in the boiler operatiopn control device, or following method: measure and be fed into broken coal supply amount and the coal of using in the grater (flintiness of coal) of coal dust, carry out the operation control (spy opens the 2003-170079 communique) of grater based on these information.
But all there is following problem in described arbitrary technology: thus coal burning boiler is set very labor intensive in the coal character that grasp is supplied to.
That is, under the situation of passing through the operation control that the operator controls many coals boiler in the past, need manually carry out data setting, thereby this problem of labor intensive on data setting etc. is arranged.Under the situation of the operation control of the many coals boiler that the ash behind the coal combustion etc. has been carried out analyze,,, expend this problem of expense thereby have on system imports so that system becomes is very complicated because analysis result need be fed back in data setting again.Again, patent documentation 1 disclosed technology is the technology in the operation of the grater control, and the gas of not considering boiler distributes the control of the aperture of damper or vapor (steam) temperature setting value etc.
Again, during coal in switching is fed into boiler, the blending ratio of putting into the coal in the boiler changes.For example, from coal A when coal B switches coal, the ratio of the coal of initial coal A is more, but the ratio of coal B increases gradually after a while.But any of conventional art can not know that all the coal of which coal of a few percent is put in the boiler at this moment, thereby following problem is arranged: boiler control during this period might become unstable.
Summary of the invention
The present invention addresses these problems, and purpose is to provide a kind of coal burning boiler for many coals to control, and makes its boiler run control method that becomes the boiler combustion corresponding with the mixing ratio of actual coal etc.
The present invention provides a kind of boiler run control method in order to solve described problem, comprising: the IC tag spreading gear is mixed in step in the coal with the IC tag that has stored the information relevant with the coal character of described coal; Described coal supplied with described coal to the stoker of boiler is supplied to step in the boiler; Read the step of the information that is mixed in the IC tag in the coal that is fed in the described boiler as the IC tag reader of the reading device of described IC tag; Carry out following step (1), (2) that the boiler operatiopn control device of the operation control of described boiler carries out, (1), determines the step of the coal character of the blending ratio of the quantity delivered of the unit interval correspondence of described each coal, described each coal and described each coal based on the information of the IC tag that reads by described IC tag reader; And (2) are based on quantity delivered, the blending ratio of described each coal and the coal character of described each coal of the unit interval correspondence of described definite described each coal, calculate the operational parameter control of described boiler, and, carry out the step of the operation control of described boiler based on the operational parameter control of described calculating.With regard to other method, will in embodiment described later, narrate.
According to the present invention, just can control for the coal burning boiler of many coals, make it become the corresponding boiler combustion of mixing ratio with actual coal.

The specific embodiment
Below, with reference to description of drawings the specific embodiment of the present invention (below, be called embodiment).
The flow process of operation control of many coals boiler of comparative example at first, is described.As example, description operation person carries out the situation of the operation control of many coals boiler at this.Fig. 1 is the figure that is illustrated in the power plant of comparative example the relation between the operation control of many coals boiler that coal is carried out from unload coal the place equipment this process and operator in being transported to boiler.
At first, transport the coal of coming from colliery all over the world, unload coal from coal carry vessel 1 by machine for unloading coal 2, and be transported to storage in the coal yard ground 3 in the place of unloading coal by coal carry vessel 1.Then, preserve in coal yard the coal in 3 be transported to boiler 20 by conveyer belt 4.This boiler 20 includes the feed bin 5 that is used for temporarily storing coal, coal is supplied to the stoker 6 of grater 7, coal is processed as the grater 7 of micropowder and makes the boiler body 8 of the coal combustion that is processed as micropowder and constitutes.If coal is transported in the feed bin 5 by conveyer belt 4, then in stoker 6, carry out the adjusting of coal quantity delivered, coal is processed as micropowder and is transported in the boiler body 8 with grater 7, thereby be utilized as the fuel of the usefulness of burning.
At this moment, because the coal of supplying with from stoker 6 is many coals,, and be input in the boiler operatiopn control device 11 so the operator selects to represent the coal code (coal ID) of the kind of the coal of mixing with the input unit of PC (personal computer) 9.Consequently, undertaken by boiler operatiopn control device 11 corresponding to the control of the selected coal code of operator.
But because only switch the coal code, boiler can not carry out the suitable burning corresponding to coal character, so the operator need adjust control setting value etc.And then, because in the handoff procedure of coal, can not know which coal with which kind of ratio is mixed, instability so control during this period might become.
(first embodiment)
The flow process of operation control of many coals boiler that boiler run control method carried out of first embodiment of the present invention then, is described.Fig. 2 is the figure of step of operation control of many coals boiler that boiler run control method carried out of expression first embodiment of the present invention.
At first, unload coal from coal carry vessel 1 by machine for unloading coal 2, and be transported to storage in the coal yard institute 3 by the coal that 1 transportation of coal carry vessel comes.
Then, the manager is by the coal of the coal that unloads, and will be input in the input unit 31 with output state, caloric value, fuel ratio, ash content, moisture and the comminuted relevant information (information of relevant coal character) of the coal of this coal.If IC tag writing station 30 receives the relevant information of coal character with input from input unit 31, then IC tag writing station 30 is written into the information of relevant this coal character in the IC tag 12.
And, unloading and be transported to from coal carry vessel 1 coal yard ground 3 these processes at this coal, IC tag spreading gear 32 mixes IC tag 12 in coal, and described IC tag 12 writes the information relevant with coal character.That is, under the situation of the unloaded information of the coal of IC tag spreading gear 32 acquisition coal A, then in this coal, mix the IC tag 12 that (broadcasting sowing) writes the information relevant with the coal character of coal A.When the unloaded information of coal that obtains coal B, then in this coal, mix the IC tag 12 that (broadcasting sowing) writes the information relevant with the coal character of coal B again.
This moment is preferred, IC tag 12, and unloaded and machine for unloading coal 2 placed coal yard institute at 3 o'clock with coal at coal, was blended in as far as possible in heterogeneity in the coal integral body, again, all was mixed in the coal with identical ratio by each coal.That is, preferably in each coal, including on the ratio of IC tag 12 and do not having deviation.This is more correctly to grasp the quantity delivered of each coal of time per unit and the blending ratio of this coal for, boiler operatiopn control device 11.
In addition, the blending ratio of Ci Shi IC tag 12 for example is about 10/t.
Then, be mixed with the coal of IC tag 12, be transported to the feed bin 5 by conveyer belt 4 from coal yard institute 3, thereby be transported to the boiler body 8 via grater 7 from stoker 6.
In this IC tag 12, have IC chip (IC integrated circuit) and be connected in antenna on this IC chip.In this IC chip, store and the output state of coal, caloric value (kJ/kg), fuel ratio (value that obtains divided by fixed carbon with volatile ingredient), moisture, ash content and relevant information such as comminuted.
Thereby, because this IC tag 12 is very small-sized (for example, 0.4mm is square etc.), so, also the operation of boiler 20 is not exerted an influence even in boiler 20, burn with coal.
If this IC tag 12 then utilizes antenna to be transformed to electric power from the electromagnetic wave that this IC tag reader 13 sends near IC tag reader 13.Then, the IC chip uses this electric power to produce the electromagnetic wave of the identifying information (ID) that writes of expression, and sends to the IC tag reader 13 from antenna.Thereby the identifying information that IC tag reader 13 can will be written in the IC chip in the mode with IC tag 12 noncontacts (wireless) reads in IC tag reader 13.
Like this, the IC tag reader 13 that is arranged on the stoker 6 reads the information of coal character by be mixed in IC tag 12 from the coal that stoker 6 is supplied with in grater 7.
Then, the information of the IC tag 12 that is read by IC tag reader 13 is sent to boiler operatiopn control device 11.Then, the number of the IC tag 12 of each coal that boiler operatiopn control device 11 is read by the IC tag reader according to time per unit is calculated the blending ratio of each coal.Again, according to this blending ratio, with the coal character that reads by IC tag reader 13, calculate the coal character of the equalization that supplies to the coal in the boiler body 8.Then, according to the coal character of this equalization, with the coal quantity delivered of time per unit, calculate the operational parameter control that boiler body 8 becomes optimal boiler combustion, thereby carry out operation control based on the boiler body of this operational parameter control.The operation control of this moment will be narrated in the back.
Fig. 3 is the calcspar of structure of the boiler operatiopn control device of presentation graphs 2.As shown in Figure 3, boiler operatiopn control device 11 have the CPU (central processing unit) 110 that carries out various calculation process, as memory 111, the realization and the network of the communicating by letter usefulness controller 112 of the IC tag reader 13 of Fig. 2 and I/O (I/O) interface 113 of boiler 20 being exported control signals used by CPU110 to the storage part in computing zone.
In memory 111, store: equalization coal character calculation procedure 15, make the information of CPU110 according to the IC tag of exporting from IC tag reader 13 12, come computational rules to supply to the coal character of the equalization of the coal in the boiler body 8 in the time; Operational parameter control calculation procedure 16, calculate the operational parameter control (dynamic guide's control signal and grater rotary speed etc. when gas distributes damper aperture, SH (SuperHeater, superheater) spraying aperture, vapor (steam) temperature setting value, water combustion ratio, load variations) of boiler 20 according to definite coal character; Boiler operatiopn control program 17 is based on the operational parameter control that is calculated, to boiler 20 output operation control signals.
In addition, the equalization coal character calculating part in the technical scheme realizes that by making CPU110 carry out equalization coal character calculation procedure the operational parameter control calculating part is realized by making CPU110 carry out operational parameter control calculation procedure 16.Again, network is equivalent to acceptance division in the technical scheme with controller 112.
Then,, use Fig. 4, the function of boiler operatiopn control device 11 is described suitably with reference to Fig. 2～Fig. 3.Fig. 4 is the figure of function of the boiler operatiopn control device of key diagram 3.At this,, illustrate that it is coal A, coal B and this situation of 3 kinds of coal C that boiler 20 uses the coal as fuel as example.
At first, read the IC tag 12 that is mixed in the coal of supplying with by stoker 6 with IC tag reader 13.Then, the information with the IC tag 12 that reads outputs in the boiler operatiopn control device 11 one by one.
The CPU110 of boiler operatiopn control device 11 is based on equalization coal character calculation procedure 15, and the information storage of the IC tag 12 that will receive via network usefulness controller 112 is in memory 111.In this information that is stored in the memory 111 is the coal character I of coal A
AThe coal character I of (symbol 40), coal B
BThe coal character I of (symbol 42) and coal C
C(symbol 44), with the number N of the IC tag 12 that is contained in the coal A in the coal of from stoker 6, supplying with in the stipulated time
AThe number N of the IC tag 12 of (symbol 41), coal B
BThe number N of the IC tag 12 of (symbol 43) and coal C
C(symbol 45).Contain caloric value, fuel ratio, moisture, ash content, information such as comminuted in this packets of information of coal character again.In addition, the information of this coal character also can further include and the output state of coal, the relevant information of ature of coal classification (anthracite, pitch coal, inferior pitch coal, brown coal etc.), caking property (non-bonding, strong bonding, weak bonding etc.).
Then, CPU110 to be stored in the data in the memory 111, calculates the coal character of the equalization that supplies to the coal in the boiler body 8 at the appointed time based on equalization coal character calculation procedure 15.
That is,, obtain the caloric value, fuel ratio, moisture, ash content of the coal of supplying with in the stipulated time, comminuted etc. mean value based on following formula (1).
[formula 1]
Then, CPU110 is based on operational parameter control calculation procedure 16, and the coal character by equalization (coal supply amount of caloric value, fuel ratio, moisture, ash content, comminuted, time per unit etc.) is calculated the operational parameter control that is used for moving efficiently boiler 20.Operational parameter control at this for example is gas distribution damper aperture, SH spraying aperture, vapor (steam) temperature setting value, dynamic guide's control signal, grater 7 rotary speeies etc. when water fires than standard, load variations of boiler body 8.This operational parameter control calculation procedure 16 for example can be realized by using the spy to open the technique known that flat 06-102905 communique put down in writing.
CPU110 carries out operational parameter control calculation procedure 16 based on the fuel ratio of the coal character of equalization.For example, CPU110 is with reference to the function (with reference to the zone 18 of Fig. 4) of the expression best SH spraying aperture corresponding with fuel ratio, come calculating optimum SH spraying aperture, perhaps by each fuel ratio, function (with reference to the zone 18 of Fig. 4) with reference to the expression best grater rotary speed corresponding with the coal supply amount, come calculating optimum grater rotary speed, thereby obtain operational parameter control.
Then,, carry out boiler operatiopn control program 17 because CPU110 is based on this operational parameter control,, even boiler operatiopn control device 11 also can carry out optimum operation to boiler 20 and control under the situation that blending ratio and the passing of time one of each coal changes.
Like this, by after coal is unloaded, coal being transported in the process on coal yard ground 3, irrespectively mix with coal with the coal class with the IC tag 12 that the ratio of a certain regulation will include about the various information of coal, and read its information by the IC tag reader 13 that is arranged on the stoker, just can correctly know from stoker 6 to supply to the information (information such as caloric value, fuel ratio, moisture, ash content, comminuted, output state, medium classification and caking property) of the many coals the grater 7 or the quantity delivered of each coal.With this, compare with the operation control of many coals boiler that the operator carried out of comparative example, can alleviate the burden of control.Again, the operation of the many coals boiler that is carried out with computer control is compared, and can reduce equipment cost.
(second embodiment)
Then,, use Fig. 5 and Fig. 6, second embodiment of the present invention is described with reference to Fig. 2～Fig. 4.Fig. 5 is the calcspar of structure of the boiler operatiopn control device of expression second embodiment.Fig. 6 is the figure of step of operation control of many coals boiler of the boiler run control method of expression second embodiment of the present invention.
Second embodiment is characterised in that IC tag 12 stores coal ID (identifying information of coal, coal code), and the information storage of the coal character of relevant this coal is in boiler operatiopn control device 11 sides.That is, as shown in Figure 5, memory 111 stores the coal property list 120 of the expression information relevant with the coal character of each coal ID.The structural element mark identical Reference numeral identical with described first embodiment omits explanation.
As shown in Figure 6, the coal that comes by coal carry vessel 1 carrying, with first embodiment in the same manner, unload coal from coal carry vessel 1 by machine for unloading coal 2, and be transported in the coal yard ground 3.Then, the manager is by the coal of the coal that unloads, and utilizes input unit 31 to import output state, caloric value, fuel ratio, ash content, moisture and comminuted relevant information (information of relevant coal character) with the coal of this coal.At this moment, to IC tag writing station 30 output coal ID, the information relevant with the coal character of each coal ID outputs in the boiler operatiopn control device 11.
IC tag writing station 32 will be written to the IC tag 12 from the coal ID of input unit 31 outputs, and this IC tag 12 is transported in the IC tag spreading gear 32.Then, the IC tag spreading gear 32 and first embodiment mix (broadcasting sowing) in coal with IC tag 12 in the same manner.
On the other hand, boiler operatiopn control device 11 then is stored in it in memory 111 as coal property list 120 if receive the information relevant with the coal character of each coal ID from input unit 31.
This coal property list 120 is as shown in table 1.
[table 1]
