Description
Technical field
The utility model relates to a kind of new combustion systems, sufficiently, pollutant emission is few, energy-saving ring for especially a kind of burning
The novel pyrolytic segmentation compacting combustion system of guarantor.
Background technique
Traditional chain row, vulcanization bed, pulverized-coal fired boiler combustion system be all that thermal decomposition gasification combustion, which mixes, is under conditions of oxygen-enriched
The combustion process of one, as the wind speed of air-introduced machine makes the tar gas of a part of not after-flame that the row's of causing black smoke be discharged.Although
More advanced pulverized-coal fired boiler basic after-flame of tar gas in burning, but coal dust firing is insufficient, makes burned pulverized coal particle
With the presence of black carbon, and dust emission is high.
Utility model content
To solve the above problems, the utility model provides, a kind of burning is abundant, and pollutant emission is few, energy-saving and environment-friendly new
Type pyrolysis segmentation compacting combustion system.
Realize the utility model aim a kind of novel pyrolytic segmentation compacting combustion system, including burner hearth and be located at burner hearth under
The defeated coal chain of side is arranged, and is disposed with the first combustion chamber, the second combustion chamber and third combustion chamber, institute from left to right in the burner hearth
State between the first combustion chamber and burner hearth left side wall, between the first combustion chamber and the second combustion chamber, the burning of the second combustion chamber and third
It is separated by multiple rows of vertically arranged heat exchange version between room, pyrotechnics mouth is provided at the top of every piece of heat exchanger plates.Described first
The lower part of the corresponding defeated coal chain row part in the lower section of combustion chamber and the second combustion chamber is provided with air blower.The right side of the burner hearth
Top is provided with air-vent.
A kind of novel pyrolytic segmentation compacting combustion system described in this patent, is divided into the first combustion chamber, the second combustion for burner hearth
Burn room and the combustion phases of third combustion chamber three, i.e. pyrolysis and combustion area, coal-char combustion area and burning-out zone.Three inside burner hearth
Heat exchanger plates are provided between stage, there are the spaces that coal seam passes through for heat exchanger plates bottom, as the burning coal layer in coal seam is thinning
Its space also reduces simultaneously, is formed and is suppressed to coal seam, and uncombusted black molecule is made to not easily pass through and enter the second combustion chamber.?
It is equipped with pyrotechnics mouth at the top of heat exchanger plates between the first combustion chamber and the second combustion chamber, pyrotechnics mouth wants small, flammable after making gasification
With pressure light of gas and the next combustion chamber of spirt.The fire box temperature for having become semicoke combustion section at this time has reached 800-1000 degree, can
The black molecule for keeping the first combustion section uncombusted is further cracked into small flammable molecule by the second combustion chambers burn.In the first combustion chamber
With by air blower forced-air blast, make oxygen in burner hearth sufficient when the second combustion chambers burn, it is logical by the hot gas of secondary after-flame
It crosses the second combustion chamber and three-barreled lower burner enters burning-out zone, and be discharged eventually by air-vent, to reach clean
The purpose of burning.
The advantages of this patent, is:
1, because fuel produces the formation of a large amount of carbon monoxide and nitrogen oxides in the pyrolytic process of the first combustion chamber
Reducing atmosphere, and part of oxygen, simple substance carbon and oxygen are generated, so also reducing nitrogen oxides while strengthen burning.
2, when the first combustion chambers burn is to a sections, furnace temperature is lower, generally at 400 degree or so, the combustible gas scale of construction that is pyrolyzed at this time
Maximum starts essentially upon coking when coal seam enters b sections of burnings, and exhaust gas volumn is opposite to want small, and CO content at this time is larger, with
The polluted gas such as nitrogen oxides, carbon monoxide form reducing atmosphere, further decrease nitrogen oxides and sulfide.
3, this patent whole design is reasonable, can carry out upgrading on the original basis, overall cost is not high, and energy-saving ring
It protects.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of this patent
Specific embodiment
As shown in Figure 1, the utility model a kind of novel pyrolytic segmentation compacting combustion system, including burner hearth 1 and be located at furnace
The defeated coal chain of 1 lower section of thorax arranges 2, is disposed with the first combustion chamber 3, the second combustion chamber 4 and third from left to right in the burner hearth 1
Combustion chamber 5, between 1 left side wall of first combustion chamber 3 and burner hearth, between the first combustion chamber 3 and the second combustion chamber 4, the second combustion
It burns and is separated by multiple rows of vertically arranged heat exchange version 6 between room 4 and third combustion chamber 5, the top of every piece of heat exchanger plates 6 is respectively provided with
There is pyrotechnics mouth 7.The lower part that the corresponding defeated coal chain in the lower section of first combustion chamber 3 and the second combustion chamber 4 arranges 2 parts is provided with
Air blower 9.The right upper portion of the burner hearth 1 is provided with air-vent 8.
A kind of novel pyrolytic segmentation compacting combustion system described in this patent, is divided into the first combustion chamber, the second combustion for burner hearth
Burn room and the combustion phases of third combustion chamber three, i.e. pyrolysis and combustion area, coal-char combustion area and burning-out zone.Three inside burner hearth
