Description

The invention relates to a power system and can be used in various technological installations for heating air, for example, as a drying agent in grain dryers, for heating agricultural premises, etc.
When burning liquid or gaseous fuels to generate heat, especially in low-power power plants, as a rule, complete combustion of fuel is not ensured. Unburned fuel settles on the walls of the combustion chamber, soot forms on them, part of unburned fuel with the air stream enters the air. Of the many air pollutants, nitrogen oxides NOx and carbon oxides CO are the most dangerous. The main amount of NOx and CO is formed as a result of incomplete combustion of fuel.
There is a known method of burning fuel and a heat-utilizing installation, in which the method of burning fuel includes heating a mixture of the initial fuel with combustion products, catalytic conversion, followed by afterburning of the converted fuel (ed. Certificate of the USSR No. 1726898, MKI F23C 9/06; F22B 33/18, bull. No. 14 publ. 04/15/1992).
A known method and device for sequential stepwise catalytic combustion of fuel, in which the depleted mixture of fuel and air is preheated with hot gas coming from the burner. The preheated mixture is then catalyzed in a catalytic reactor and then burned to produce hot gas heated to a temperature above the fuel ignition temperature. The second and third portions of the depleted air-fuel mixture are then sequentially introduced into the hot gas, while their temperature exceeds the ignition temperature, which contributes to the homogeneous burning of these portions of the mixture. This homogeneous combustion is enhanced by the presence of three radicals created during the catalysis of the first portion of the mixture. Further, the catalytic reactor operates in such a way as to ensure the stability of the combustion of the lean mixture (second and third portions) (Method and apparatus for sequentially staged combustion using a catalyst. US Pat. No. 5,623,819, MKI F23R 003/40, 1997).
A known method of combustion and a burner for its implementation. According to this technical solution, the first stage of combustion takes place in a catalytic reactor, then the fuel flow is burned in a catalytic reactor together with the exhaust gas coming from the catalytic reactor, is fed to the second stage of combustion to form a uniform flame by self-ignition (ignition). If the fuel from the air-fuel mixture is only partially burned in the first stage in the catalytic reactor, and the unrefined fuel residue is burned in the second stage, then the combustion can be stabilized in such a way that the fuel-containing exhaust gas from the catalytic reactor between the outlet from the catalytic reactor and a uniform flame is passed through special devices which aerodynamically stabilize a uniform flame (Combustion method and burner for carrying out the method. US Pat. No. 6,896,509, MKI F23D 014/22, May 2005).
The given technical solutions are intended for burning fuel in powerful industrial stationary boiler plants, gas turbines, etc. In such installations, as a rule, powerful air compressors with a powerful electric drive and high energy consumption are used. In addition, such installations are designed to operate only on gaseous fuels.
A known preparation method and a device for burning fuel with a fuel supply unit for receiving a stream and supplying it to the pipeline. This creates a turbulent flow of fuel. Fuel is affected by a combination of elements in a mixture or elementwise (copper, aluminum, stainless steel, magnesium, barium, calcium, etc.), which change the chemical composition of the fuel supplied to the combustion, changing the molecular bonds in the fuel by catalysis. The fuel, regardless of its type, is then dispersed using small nozzles located throughout the furnace. This decreases the density of evaporation (vaporization) of the fuel. At the same time, the efficiency of fuel combustion increases (Fuel conditioning assembly. US Pat. No. 6,915,789, MKI F02M 033/00, 1997).
This method of combustion involves the use of multiple nozzles, which requires complex adjustment of the fuel and air supply to the nozzles and maintaining sustainable combustion.
Devices for implementing this method are extremely complex in design, expensive to manufacture, maintain, repair, and therefore cannot be used in small-scale energy, in particular in agriculture.
There is a known method of burning fuel to generate heat and an air heater for its implementation, which for the purpose and for most of the similar features is adopted as prototypes of the first and second claimed inventions, respectively (Mixing catalytic air heater VGSK, considered in the article by Ismagilov 3.R. and Kerzhentseva M.A. “Ecologically clean burning of fuels and catalytic purification of flue gases of TPPs from nitrogen oxides: state and prospects”, published in the Journal of the All-Union Chemical Society named after D.I. Mendeleev a, volume XXXV, section “Chemistry in Environmental Protection”, 1990, No. 1, p. 47 Fig. 5, and also in the leaflet “Ecological Clean Air Heater of VGSK” of the G.K. Boreskov Institute of Catalysis, Siberian Branch of the Russian Academy of Sciences. A copy of the leaflet is attached to the application).
The prototype of the first invention (method) includes supplying fuel to the burner while supplying primary air, burning fuel mixed with primary air in the flame tube of the combustion chamber, then introducing secondary air into the flame tube, afterburning the fuel not burnt in the combustion gases in the afterburner, dilution air flow of hot gases exiting the afterburner, and the withdrawal of heated air for use for its intended purpose. With this method, in the entire cavity of the combustion tube of the combustion chamber, multi-torch combustion of fuel (natural gas) is carried out, providing a high (at least 85%) degree of combustion. For this, the fuel volume is preliminarily divided into several small volumes using a rather complicated multi-burner device.
The prototype method does not have versatility (by type of burner and type of fuel) for the following reason. For its implementation, it is impossible to use single-torch widespread typical burners, including burners for liquid fuels. When using single-torch burners in this method, a significant part of the fuel that has not burned in a single stage in the flame tube of the combustion chamber, due to the low degree of fuel combustion in the flare (no more than 60%), will enter the afterburner, disrupting its operation.
The prototype of the second invention (air heater) includes a burner with a primary air fan, a combustion chamber with an external casing and a flame tube having openings for introducing secondary air into it, placed in the external casing with the formation of an annular channel between the flame tube and the external casing, and also an afterburner fuel not burnt in the flue gases. The VGSK heater, according to the prototype method carried out by it, is equipped with a complex multi-nozzle burner device for burning natural gas.
The disadvantage of the prototype air heater is the lack of its versatility, namely the impossibility of using widespread standard single-torch burners for liquid or gaseous fuel in it. This disadvantage is due to the aforementioned disadvantage of the prototype method implemented by him, designed for multi-torch combustion of fuel (natural gas) in the entire volume of the flame tube of the combustion chamber with subsequent afterburning. In other words, the VGSK design does not allow for a high (at least 85%) degree of fuel combustion during single-torch combustion in the flame tube of the combustion chamber, and with a lower degree of primary fuel combustion, the afterburner does not fulfill its function.
The objective of the first invention is to ensure the versatility of the method of burning fuel to generate heat by increasing the degree of fuel burning in the flame tube of the combustion chamber when using single-torch burners for liquid or gaseous fuel, that is, eliminating the disadvantage of the prototype method.
The objective of the second invention is to ensure the versatility of the air heater by creating conditions for the implementation of the claimed method of burning liquid or gaseous fuels.
The objective of the first invention is solved in that the claimed method of burning liquid or gaseous fuel to produce heat, as well as its prototype, includes supplying fuel to the burner while supplying primary air, burning fuel mixed with primary air in the flame tube of the combustion chamber, and then introducing it into secondary air flame tube, afterburning of fuel not burned in the flue gases in the afterburning chamber, dilution with air of the flow of hot gases leaving the afterburning chamber, and the outlet of heated air for use oi for the intended purpose. However, unlike the prototype method, in the inventive method, the fuel is burned with its afterburning in three stages, in the first of which the fuel mixture with primary air is burned with a low coefficient of excess primary air, and in the second, the resulting burning air-fuel mixture is distributed around the periphery of the fire pipes of the combustion chamber, while the mixture is vortexed and mixed with part of the secondary air, the introduction of which into the flame tube is carried out in at least two of its zones, the resulting mixture with a high coefficient of excess air int nsivno burn, the third - is introduced into the flame tube the remainder of the secondary air, lower than the temperature of the flue gases, enter them into the afterburning chamber and afterburning it is not burned fuel in the flue gas (incomplete combustion products).
The aforementioned new set of essential features of the claimed method, additionally including a stage of intensive fuel combustion (second stage), in all cases of its implementation increases the degree of fuel combustion in the combustion tube of the combustion chamber when using typical single-torch burners for liquid or gaseous fuel, that is, it provides a technical result specified in the task of the first invention.
The objective of the second invention is solved in that the inventive air heater for burning liquid or gaseous fuels to produce heat, as well as its prototype, includes a burner with a primary air fan, a combustion chamber with an external casing and a flame tube having openings for introducing secondary air into it, placed in the outer casing with the formation of an annular channel between the flame tube and the outer casing, as well as the afterburning chamber of the fuel not burnt in the flue gases. However, unlike the prototype, the claimed heater additionally contains a separate secondary air fan connected to the cavity of the outer housing of the combustion chamber, and a swirl in the form of a hollow conical mixer installed in the flame tube and separating it into the primary and secondary heat chambers. The primary heat chamber is located between the burner and the swirl, and the secondary - between the swirl and the afterburner. In this case, the holes for introducing secondary air into the flame tube are located in at least two zones of the secondary flame chamber, the first of which is closer to the swirl, the second to the afterburner, and the annular channel formed between the flame tube and the outer housing of the combustion chamber is closed with sides of the afterburner.
The separation of the flame tube into the primary and secondary combustion chambers by installing a swirler in it in conjunction with the other named common essential features in all cases of the second invention, allows to implement the claimed method of three-stage fuel combustion. This provides the necessary degree of fuel combustion in the combustion tube flame tube when using purchased burners for liquid or gaseous fuel and efficient afterburning of fuel residues in the afterburner.
In addition, in special cases of the implementation of the claimed air heater, its afterburner is made in the form of a separate unit connected to the combustion tube of the combustion chamber. This reduces the need for expensive heat-resistant steel for the manufacture of a flame tube and afterburner.
In addition, the part of the afterburner connected to the flame tube is made expanding along the flue gases. This provides an opportunity to better burn out the remnants of fuel not burnt in the flue gases at a sufficiently high heat output of the air heater.
In addition, the air heater has an air intake and a heated air fan located remotely from the entrance window opposite the exit of the afterburner, and the air intake is connected to the fan inlet and is designed as a screen covering at least part of the combustion chamber and the afterburner with the formation between it and named chambers of the annular channel for the passage of external heated air to the fan. The presence of these elements, their location and the relationship expands the functions of the heater, reduces heat loss, ensures the creation of a uniform, temperature intensively pumped flow of heated air and the necessary compactness of the heater.

The heater for implementing the inventive method includes a burner 1 for burning liquid or gaseous fuel with a primary air fan, a combustion chamber with an outer casing 2 and a flame tube 3. The burner head 1 is located in front of the flame tube 3 coaxially with it. The flame tube 3 has openings 4 and 5 for introducing secondary air into it, is located in the outer housing 2 of the combustion chamber and forms an annular channel 6 with it for supplying secondary air. The air heater also has a afterburner 7 of fuel not burned in the flue gases with an afterburner 8, for example, made in the form of a honeycomb ceramic catalytic cartridge.
For high-quality combustion of liquid or gaseous fuels when working with the corresponding widespread typical burner 1, including a single torch, the air heater has a separate secondary air fan 9 connected to the cavity of the external housing 2 of the combustion chamber, and a swirler 10 made in the form of a hollow conical mixer. The swirler 10 is installed in the flame tube 3 and divides it into primary A and secondary B fire chambers. The primary flame chamber A is located between the burner 1 and the swirl 10, and the secondary B is between the swirl 10 and the afterburner 7 with the cavity B. The annular channel 6 between the flame tube 3 and the outer case 2 of the combustion chamber is closed on the side of the afterburner 7, for example, a ring, having a thermal gap between it and the flame tube 3. Holes 4 and 5, intended for distributed entry into the flame tube 3 from the annular channel 6 of the secondary, including cooling, air, are located in at least two zones of the secondary flame chamber B. The first of these s it with holes 4 is located closer to the swirler 10, the second zone with holes 5 for cooling and oxygen enrichment of the flue gases to the afterburner 7.
In this example, the afterburner 7 is designed as a separate unit connected to the combustion tube 3 of the combustion chamber. In addition, the part of the afterburning chamber 7, connected to the flame tube 3, is made with the expansion in the direction of movement of the flue gases in it. This improves the operation of the afterburning chamber 7 by increasing the working volume of its cavity B and afterburner 8, which allows to increase the thermal power of the air heater.
To pump heated air, for example, in installations for drying agricultural products by active ventilation or in a network for heating several rooms, the air heater has an air intake 11 and a heated air fan 12 located remotely from the entrance window opposite the exit of the afterburner 7. The inlet window of the fan 12 is connected to the air intake 11, which is made in the form of a screen covering a part of the outer housing 2 of the combustion chamber and the afterburner 7 with the formation of an annular channel between it and the said chambers for the passage of external heated air to the fan 12.
The claimed method is carried out, when the proposed heater, as follows.
Liquid or gaseous fuel under pressure is supplied to the burner 1, in particular of a single torch type, into which primary air is simultaneously pumped by its fan. In the primary combustion chamber A of the flame tube 3, at the end of which the head of the working burner 1 is located, the first stage of fuel combustion is carried out, that is, flare (diffusion) combustion of the fuel in a mixture with primary air occurs with an excess air coefficient α = 0.3 ÷ 0, four. Next, the second stage of combustion begins, that is, the air-fuel mixture burning in the primary fire chamber A is directed to the swirl 10, flowing around it, enters the secondary fire chamber B. Due to this and the swirl 10 considered below, the flame-combustion flow of the air-fuel mixture is distributed around the periphery of the fire tube 3.
The flow of secondary air by the fan 9 is pumped into the cavity of the housing 2 of the combustion chamber, enters the annular channel 6 located between the housing 2 and the flame tube 3. The bulk of the secondary air continues to move in the annular channel 6, and part of it from this channel is directed to the swirler 10 in which it twists. The swirling air jets leaving the swirler 10 are combined with the burning air-fuel mixture flowing around it, swirling and effectively mixing it with the secondary air coming from the annular channel 6 into the secondary heat chamber B through openings 4. In the secondary chamber B of the heat pipe 3, the main process the second stage, that is, fuel is intensively burned with an excess air coefficient α = 1.5 ÷ 2.5. At the same time, the concentration of nitrogen oxides and carbon monoxide in the products of combustion decreases many times, the speed and temperature of the combustion zones increases, ensuring a complete combustion of the fuel of at least 85%.
Known means regulate the fuel consumption in the burner 1 and the performance of the secondary air fan 9, thereby setting the maximum temperature in the intensive combustion zone not higher than 1800 ° C, which greatly reduces the likelihood of formation of nitrogen oxides.
Preparation for the third stage of fuel combustion begins in the zone of the secondary combustion chamber B adjacent to the afterburner 7. In this case, from the annular channel 6 through the openings 5, the rest of the secondary air is introduced into the flame tube 3, which is effectively mixed with swirling flue gases, cooling and enriching their oxygen. The temperature of the flue gases before entering them into the afterburner 7 decreases to a value acceptable for the afterburner 8, for example, to a temperature of 500 ÷ 800 ° C, rational for the afterburner 8, made in the form of a cellular ceramic catalytic cartridge.
From the combustion tube 3 of the combustion chamber, the cooled and oxygen-enriched flue gases enter the cavity B of the afterburner 7. Due to the expansion of the initial section of the afterburner 7, the flow rate of the flue gases decreases. In all, a sufficiently large volume of the cavity B and in the afterburner 8 of this chamber, afterburning, up to 99.5%, of the remaining fuel not previously burnt in the flue gases occurs. This process proceeds at a low temperature, which eliminates the formation of nitric oxide, contributes to a more efficient afterburning of fuel residues, and further reduces the concentration of harmful gases (CO, CH).
At the end of the third stage of fuel combustion, hot gases purified from the products of incomplete combustion of fuel in the afterburning chamber 7 leave this chamber and are diluted with outside air, heating it to a predetermined temperature. Heated air is used for its intended purpose, for example, due to the vacuum created by an autonomous fan, it enters the heating system or the receiving agent system of the drying agent for drying agricultural products.
In this example, the external air due to the vacuum created by the fan 12 enters the air intake 11 and passes through the annular channel between it, the outer casing 2 of the combustion chamber and the afterburner 7. In this case, the air is heated, cooling the walls of the chambers 2 and 7, which increases the term their service and reduces heat loss. Next, this air is directed into the inlet window of the fan 12, into which hot gases leaving the afterburning chamber 7 simultaneously enter and dilutes them, heating to a predetermined temperature. The heated air is effectively mixed with hot gases, passing through the fan 12, and leaves its discharge window in the form of an intense temperature-uniform stream for use for its intended purpose.
Based on the claimed group of inventions at the Siberian Agro-Industrial House OJSC (SAD OJSC) of the Siberian Branch of the Russian Academy of Agricultural Sciences (SB RASHN), an experimental sample of an air heater (universal catalytic heat generator UGTK-0.45 PIONER) was created and tested, designed to work with standard, including single-torch, burners for liquid or gaseous fuels. Its indicators are as follows: maximum power 0.45 MW; thermal power in the air 215 ÷ 385 Mcal / h; the greatest supply of heated air is 18 thousand m 3 / h; degree of air heating 30 ÷ 70 ° C; the total pressure of the heated air at the outlet of the fan is 1000 Pa; fuel consumption - when working on gas 18 ÷ 32 m 3 / h, when working on liquid fuel (diesel) 22 ÷ 38 kg / h; thermal efficiency of 99.5%.
When heating 2200 m 3 of seedling-vegetable greenhouses with the declared air heater, the content of harmful substances did not exceed the MPC norms for the working area, and the automatic control system ensured that the temperature in the greenhouse was maintained at the level of specified parameters.
