Abstract
The utility model discloses a retort injecting coal gas boiler, comprising a coal bucket, a retort chamber, a combustion chamber, a secondary air pipe, a flower arch, a coal piling board, a piecewise air chamber and a heat convection change surface. The coal enters into the retort chamber by the coal bucket and the coal layer is ignited on the bottom portion and is pyrolyzed on the anoxic condition of the retort chamber to gradually separate the volatile matter of heavy hydrocarbon and other matter easy to generate black smoke to form retort coal gas. the resort coal gas is injected into the combustion chamber by an injecting hole. The bottom portion of the resort chamber separates the semi-coke carbon of the volatile matter to push a coal push board into the combustion chamber for combustion. The semi-coke of gas state and solid state conducts mixing combustion in the combustion chamber and also hot secondary air is mixed for stirring and the upper portion is provided with the flower arch reflection. The temperature in the combustion chamber is high and the stay time of the combustion gas is long and thus the combustion semi-coke has high heat efficiency (higher than 95%) without black smoke generation. The purposes of high heat efficiency, low pollutant discharge and low running cost are obtained.
Description
Technical field:
The utility model belongs to the coal-burning boiler environmental technology field.
Background technology:
The atmosphere pollution of China is the atmosphere pollution in " three Norths " area particularly, mainly is that the bituminous coal type that boiler, kiln fire coal cause pollutes.Restructuring the use of energy, use clean energy resourcies such as oil, gas, solar energy, is the basic outlet that solves and control atmosphere pollution.But the present energy of China expects 2010 still based on coal, and coal still accounts for 70% of China's total energy.Therefore, greatly developing and use clean coal technology is the task of top priority, also is the inevitable course.At present, boiler generally has coal-burning boiler, oil burning boiler, gas fired-boiler and boilers heated electrically.Coal-burning boiler reduces heat cost, by people's extensive use owing to adopt this a kind of cheap fuel of coal greatly.But coal-burning boiler can produce a large amount of flue gases and SO owing to directly use coal combustion
2, pollutant such as NO, make atmospheric environment cause pollution.Simultaneously, directly use the coal burning heat loss big; The thermal efficiency is low.Coal changes into gas-fired, is that the coal clean burning reduces important measures of polluting.But present most gas generator and boiler are provided with respectively, connect with pipeline, and complex structure, floor space is big, equipment manufacturing cost is high, and the gas generator coal tar that has been in operation is separated out and caused secondary pollution in addition.
Summary of the invention:
In order to overcome the baroque deficiency of coal-burning boiler contaminated environment and gas boiler, the utility model provides a kind of destructive distillation to spray gas boiler.Low, the characteristic of simple structure of the operating cost that this boiler has coal-burning boiler also has the advantage that the gas fired-boiler pollutant emission is low, the thermal efficiency is high.Can be applicable to miniature boiler, reach higher environment protection emission requirement.
The technical solution of the utility model is:
Gas boiler is sprayed in a kind of destructive distillation, comprises coal bunker, destructive distillation chamber, combustion chamber, secondary air channel, flower arch, coal bulk board, segmentation air compartment, heat convection face.It is characterized in that destructive distillation chamber front end is connected with coal bunker, there is the heat conduction wall to be separated by between rear end and the combustion chamber, heat conduction wall bottom has coke outlet, heat conduction wall top that secondary air channel is arranged, the coke outlet bottom is a fire grate, the fire grate upper front end is equipped with coal-pushing plate, be the segmentation air compartment below the fire grate, top of combustion chamber is the flower arch, has through hole that combustion chamber and stream are changed face in the flower arch and is communicated with.
Coal enters the destructive distillation chamber by coal bunker, ignite in the bottom in the coal seam, pyrolysis under the anoxia condition of destructive distillation chamber, the fugitive constituents such as heavy hydrocarbon that will be easy to generate black smoke are separated out gradually, form dry distillation gas, dry distillation gas sprays into combustion chambers burn through spray-hole, the semicoke carbon of fugitive constituent is sloughed in bottom, destructive distillation chamber, is pushed combustion chambers burn by coal-pushing plate, gaseous state and solid-state semicoke mixed combustion in the combustion chamber, and there is hot secondary wind to sneak into stirring, and the reflection of flower arch is arranged at top, burning indoor temperature height, and the burning gases time of staying is long, so the semicoke thermal efficiency height (greater than 95%) of burning does not have black smoke to produce.Reach thermal efficiency height, pollutant emission is low, operating cost is low purpose.
Description of drawings:
Fig. 1 is a concrete structure schematic diagram of the present utility model.
(1) segmentation air compartment (2) fire grate
(3) coal-pushing plate (4) destructive distillation chamber
(5) combustion chamber (6) heat conduction wall
(7) coal bunker (8) secondary air channel
(9) flower arch (10) heat convection face
(11) spray-hole (12) fire door
(13) controllable register (14) blast pipe
The specific embodiment:
By steel plate welding and refractory material casting manufacturing, coal bunker (7) is welded by steel plate by body of heater shown in Figure 1; There is seal cover the upper end, prevents that fugitive constituent gas from overflowing.Coal is ignited in the bottom by coal bunker (7) the destructive distillation chamber (4) of packing into, the coal seam is subjected to heat conduction wall (6) and the underfired hot generation destructive distillation of being heated of transmitting, the volatilizations such as heavy hydrocarbon that will be easy to generate black smoke are separated out gradually, forming dry distillation gas is sprayed by spray-hole (11), lighted by the hot semicoke on the grate furnace (2), because sufficient oxygen supply, the abundant oxidizing fire of fugitive constituent are arranged this moment, the formation condition of not heavy carbon compound and carbon black is not discharged so boiler has black smoke.The semicoke that fugitive constituent is sloughed in bottom, destructive distillation chamber (4) is shifted onto combustion chamber (5) bottom fire grate (2) by coal-pushing plate (3) and is gone up and feed a large amount of air, it is burnt, like this in main chamber, dry distillation gas and semicoke burn respectively according to separately burning feature and mode and connect each other, mutually promote, and combustible in the flue gas are reached or near completing combustion.The air capacity that controllable register (13) control enters combustion chamber (5) and lining, destructive distillation chamber (4) makes ignition temperature control within the specific limits, can produce dry distillation gas and can produce enough semicoke supply combustion chambers burn again, makes stable operation of the boiler.After-flame gradually after fire grate (2) is gone up combustible to be pushed to stove is discharged out of the furnace by fire door (12) at last.
