Described ash discharge chamber is connected to grate below, and the outer Hymecromone of body of heater inner bag and body of heater is crossed ash discharge chamber and is interconnected; Ash discharge chamber's installing inclined floor, base plate end connects ash discharge spiral, the convenient burning ashes of discharging.
For can be cooling and safeguard that grate, described grate are movable, the cooling room that the position installing of the corresponding grate of the outer courage of body of heater can accommodating grate retraction, this cooling room is communicated with ash discharge chamber; For convenience of movable grate retraction, in this cooling room, be provided with guide rail, guide rail front end installing baffle plate, can scrape ash discharge chamber by grate top ashes.
For preventing the operation of vapourizing furnace continuous high temperature, produce distortion, described body of heater top installing interlayer end socket, this interlayer end socket connects body of heater inner bag and outer courage.
Biomass cracking gasification stove of the present utility model, the sandwich structure of body of heater, when gasifier operation, interlayer blast inlet is introduced cold wind, both for furnace wall and grate cooling, the hot blast after heat absorption can be formed to hot gas flow again and enter movable grate bottom and gas jet, adopt thermal cracking gasification mode from the top down, situation hot gas flow and scission reaction layer at limit oxygen fully merge, and the ashes after gasification do not have carbon granule and ash, reach perfect combustion.This furnace type structure is rationally compact, easy to use, and operating safety is stable.
Accompanying drawing explanation
Fig. 1 is the structure sectional view of embodiment 1 of the present utility model;
Fig. 2 is the structure sectional view of embodiment 2 of the present utility model;
Fig. 3 is the structure sectional view of embodiment 3 of the present utility model.
Embodiment
Followingly by reference to the accompanying drawings the utility model is explained.
As shown in Figure 1, biomass cracking gasification stove of the present utility model, its structure comprises that body of heater 1, body of heater are the sandwich structure of inner bag 11 and outer courage 12; Opening for feed 8 and gas jet 9 are arranged on upper of furnace body, are communicated with body of heater inner bag, and wherein opening for feed is opened in body of heater top, and gas jet is opened in body of heater top sidewall; Blast inlet 10 is communicated with the outer courage of body of heater, and fixed grate 3 is installed in body of heater inner bag bottom, and outer courage is connected with inner bag below grate; Ash discharge chamber 5 is arranged on bottom of furnace body, and bottom of furnace body has ash door 51, conveniently claws larger ashes.
When biomass cracking gasification furnaceman does, from the opening for feed at body of heater top, be fed into inner bag, cold wind enters interlayer heat absorption fast from blast inlet, with temperature in stove, heat up, form hot gas flow and penetrate from grate bottom, under the condition of limit oxygen, adopt trans pyrolysis gasification from the top down.Not yet the hot gas flow intersection of the bed of material of gasification bottom and rising has preheating and drying effect.Complete the layer that once feeds intake, the thick sustainable combustion gasification of bed of material a few hours, aerogenesis is stable.The hot gas flow from interlayer of regulating gas nozzle can be controlled torch firing flame size.
Embodiment 2
Compare with embodiment 1, gas jet 9 is opened in body of heater top, and opening for feed 8 is opened in body of heater top sidewall.Gas jet can be opened in cephalic par or the top sidewall of body of heater.
As relatively large biomass cracking gasification stove, ash discharge chamber 5 is connected to movable grate 3 belows, ash discharge chamber's installing inclined floor 51, and base plate end connects ash discharge spiral 7, the convenient ashes of discharging.
