The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies the utility model.
Shown in accompanying drawing, the gasification coal stove of the utility model, it has the body of heater that is made up of body of heater shell 25, inboard wall of furnace body 26; Gasification cylindrical shell 28 is arranged in the body of heater, be communicated with the end of the lower air conduit 9 on air blast 11 air outlets pass the body of heater bottom whereabouts hawk 3, on fall and be positioned at blast cap 7 behind the hawk 4, mix casing 15 and take the top that is placed on body of heater; Mixing casing top has venthole 36, and the upper side of body of heater is communicated with smoke tube mouth 24, is communicated with end at the upcast ventilation pipe 13 on air blast 11 air outlets near the air inlet 14 that mixes on the casing; Exhaust vent 29 is arranged on the blast cap 7; On fall hawk 4 and can on the terminal whereabouts hawk 3 that rotates of lower air conduit, ash-falling hole 30 and another ash-falling hole 32 be arranged respectively, delivery port 19, water return outlet 31 respectively and the spatial communication between the body of heater shell, inboard wall of furnace body, bell 37 is arranged at the body of heater top.
During use, take off bell earlier, will mix casing again and take out, fine coal is sent in the gasification cylindrical shell, and fine coal is ignited, put into the mixing casing then, cover bell through kindling from upper of furnace body.Because the gasification cylindrical shell is in the state of sealing, coal produces burn incompletely, produces a large amount of CO gas and flue gas.These gases are discharged from venthole 36 through the air inlet 14 that mixes on the casing, burn after lighting, and burn the water in the hot body of heater.The wind-force that air blast produces plays the combustion-supporting effect to fine coal and carbon monoxide gas, flue gas.Can connect handle 2 on the hawk of whereabouts, rotate through handle pulling whereabouts hawk, make the two ash-falling hole alignment that fall on the hawk, the coal ash that pulverized coal friring produces can be discharged through the ash-falling hole of the upper and lower hawk that falls.
Obviously, air blast and upper and lower airduct can be positioned at the casing that separates with water body of heater that be separated out specially of body of heater, and air blast also can be positioned at the outside of body of heater.The air outlet of air blast can be connected with upper and lower airduct respectively through three-way pipe 10.Valve 12 and another valve 8 can be arranged respectively on the upper and lower airduct.Exhaust vent on the blast cap preferably is positioned on the cylinder and is downward-sloping.
The horizontal outgassing groove 35 that communicates with venthole 36 is arranged on described mixing casing 15, above the mixing casing the rotating plate 23 of giving vent to anger is arranged, last venthole 34 is arranged on the plate of giving vent to anger, be fixed with dwang 21 on the plate of giving vent to anger, the dwang upper end is fixed with link 20.Like this, can will mix casing through link takes out; Also can rotate the plate of giving vent to anger through link, dwang, the last venthole above it is alignd with venthole on mixing casing, carbon monoxide and flue gas upwards spray and burn, and can carry out cooking and operate.In the time of need not carrying out the cooking operation, rotate the plate of giving vent to anger again, make it block venthole, carbon monoxide and flue gas will flow out from horizontal outgassing groove 35, and after lighting, the water in the heating furnace body is realized heating.
In described body of heater side fire door tube 5 is arranged, the fire door tube communicates with gasification cylindrical shell 28 after passing body of heater.Like this, can coal be ignited, improve the convenience of using through the fire door tube.After igniting, can be on fire door tube outer end cap enclosing cover, get in the gasification cylindrical shell from the fire door tube to prevent air.Can also smash the slag of sintering through the fire door tube, be convenient to it and fall.
Between described gasification cylindrical shell 28 and inboard wall of furnace body 26, heat-transfer matcrial layer 27 is arranged.The heat-transfer matcrial layer can be processed by SiO 2 powder or other heat-transfer matcrials.Through the heat-transfer matcrial layer, the heat that can improve in the gasification cylindrical shell conducts the efficient to the water in the body of heater.
Under the hawk of whereabouts, ash bucket 1 can be arranged, the ashes that fall with reception.The following of whereabouts hawk has baffle plate 6 to be fixed on the lower air conduit.Mixing casing takes on the upper plate 16 that is placed on inboard wall of furnace body.Giving vent to anger can have support tube 17 above the plate 23, places infrared ray tray for combustion 22 on the support tube.Can be communicated with thermometer 18 on the body of heater.Give vent to anger plate can through bolt 33 with mix casing and link together.
