Put and lime-ash is transported to coal cinder yard.
Preferably, the structure of ash-pan driving gear is so set：Ratchet is provided with the bottom position of ash-pan, in ratchet
Diametrically opposite position is respectively provided with a hydraulic cylinder, and hydraulic cylinder drives ratchet to pull ash-pan to rotate.
Preferably, gas generator is connected with cyclone dust collectors.The crude gas of coming out of the stove of generation is removed by cyclone dust collectors
Dust is removed, is then sent to kiln.
Preferably, disc valve is connected with after cyclone dust collectors.Disc valve is used to cut off gas generator heating gas.
Preferably, it is provided with belljar valve at gas generator gas exit.Belljar valve is risen suddenly in gas pressure
Height, which plays safety when exceeding rated maximum pressure and diffuses and light a fire in gas generator or be used as during the hot brush of hot standby, blowing out, to be put
Dissipate effect.
Preferably, being arranged with water leg in the middle part of gas generator, some vapor uptakes, water folder are provided with the top of water leg
Set bottom is provided with water inlet pipe and blow-off pipe, and furnace chamber hole is provided with the middle part of water leg.The hot water of steam header outflow flows to water leg
Bottom, water in water leg heats up due to being transmitted through the heat that comes by the bed of material in gas generator burner hearth, produces steam
With the mixture of water.Furnace chamber hole is to be used to use when point stove, maintenance.
Preferably, gas generator includes body of heater and bell, body of heater or bell are provided with fire exploring hole, and fire exploring hole is by filling in
Son, shell and nozzle composition.The effect of fire exploring hole is：Fuel layer surface is observed by fire exploring hole, adjusts the working of a furnace in time
And deep layer adjustment is carried out to fuel bed；The temperature and distribution situation of each level in coal gas reacting furnace are visited with hammer drill, to instruct coal
The operation of solid/liquid/gas reactions stove.
Therefore, the utility model has the advantages that：Vapours caused by gas generator can be reclaimed
Utilize, save the energy.
