Description
Technical field
The utility model relates to a kind of coal gas conversion stove.
Background technology
Coal gas conversion stove is the device that coal gas and burning generation heat energy take place, the principle that its coal gas takes place is that mist with air and water vapour is as vaporization agent, coal from top to bottom, vaporization agent from bottom to top carries out countercurrent movement, produce chemical reaction and exchange heat such as oxidation, reduction, destructive distillation mutually, thereby produce coal gas.Concrete principle is: coal adds in the stove, after drying, becomes coke at 400～550 ℃ after separating out fugitive constituent and other destructive distillation product (CH4 methane, CmHn hydro carbons), coke through peroxidating, carry out reduction reaction, produce coal gas; Coal gas and fugitive constituent and other destructive distillation product (CH4, CmHn) enter the burner of back through gas exit, mix with secondary wind and burn, and produce heat.
Traditional its furnace wall of gas reforming stove is to adopt the monotubular formula, and the water vapour that feeds in the burner hearth is that the outer steam pipework that connects inserts, and the problem of Cun Zaiing is like this: furnace wall possibility Yin Wendu is too high and burn, and security is not high; Body of heater need use refractory materials such as refractory brick, and it is many that material expends; Extraneous steam raising plant and steam pipework, structure burden.
Summary of the invention
In order to solve the problems referred to above that existing coal gas conversion stove exists, the utility model proposes a kind of furnace wall long service life, safe to use, the coal gas conversion stove of saving material, compact conformation.
The utility model adopts following technical scheme:
A kind of coal gas conversion stove comprises body of heater, and described body of heater lower end sets out ash-pit, the inner chamber of body of heater is a burner hearth, described body of heater bottom connects steam pipe and airduct that communicates with burner hearth, and a described airduct connects air blast, on the described airduct butterfly valve is set one time; Described upper of furnace body is provided with gas exit, and described gas exit connects burner, and the secondary air channel that is connected with described air blast feeds in the described burner, and the secondary butterfly valve is set on the described secondary air channel; The furnace wall of described body of heater is provided with water filling port and steam (vapor) outlet for injecting the chuck of demineralized water on the described chuck, described water filling port connects outside inlet pipeline, and described steam (vapor) outlet communicates with an end of described steam pipe.
Further, described body of heater is provided with the water level meter that can detect water level in the described chuck.
Preferably, described burner is a burner.
Technical conceive of the present utility model is: be arranged to jacket type by the furnace wall of coal gas being changed stove, the demineralized water that injects in the chuck has cooling effect to the chuck internal layer of being close to burner hearth, can avoid chuck internal layer Yin Wendu too high and burn, so body of heater long service life, safe; Simultaneously, the heat that the demineralized water in the chuck can fully absorb again in the burner hearth produces steam, and feeds in the burner hearth by steam pipe, to supply with the usefulness that produces the chemical reaction of coal gas in the burner hearth.
The beneficial effects of the utility model are: the use of can lowering the temperature of (1) furnace wall, long service life, safe; (2) body of heater need not to use refractory materials such as refractory brick, saves material cost; (3) can save external steam generation device and steam pipework, compact conformation.

The specific embodiment
With reference to Fig. 1-3: a kind of coal gas conversion stove, comprise body of heater 1, described body of heater 1 lower end sets out ash-pit 2, the inner chamber of body of heater 1 is a burner hearth 3, described body of heater 1 bottom connects steam pipe 4 and airduct 5 that communicates with burner hearth 3, a described airduct 5 connects air blast 6, on the described airduct 5 butterfly valve 7 is set one time; Described body of heater 1 top is provided with gas exit 17, described gas exit 17 connects burner, described burner is a burner 9, and the secondary air channel 10 that is connected with described air blast 6 feeds in the described burner 9, on the described secondary air channel 10 secondary butterfly valve 11 is set; The furnace wall of described body of heater is provided with water filling port 16 and steam (vapor) outlet for injecting the chuck 12 of demineralized water on the described chuck 12, described water filling port 16 connects outside inlet pipeline, and described steam (vapor) outlet communicates with an end 8 of described steam pipe 4.
Described body of heater 1 is provided with the water level meter 13 that can detect water level in the described chuck 12.
Also be provided with fire door 14 and igniting and breast hole 15 on the described body of heater.
This programme is arranged to jacket type by the furnace wall of coal gas being changed stove, and the demineralized water that injects in the chuck has cooling effect to the chuck internal layer of being close to burner hearth, can avoid chuck internal layer Yin Wendu too high and burn, so body of heater long service life, safe; Simultaneously, the heat that the demineralized water in the chuck can fully absorb again in the burner hearth produces steam, and feeds in the burner hearth by steam pipe, to supply with the usefulness that produces the chemical reaction of coal gas in the burner hearth.
Present embodiment only is enumerating utility model design way of realization; protection domain of the present utility model is not limited only to the described concrete form of present embodiment, and protection domain of the present utility model reaches in those skilled in the art according to the thinkable equivalent technologies means of technical conceive of the present utility model.
