The invention discloses a gasification heat-accumulation
combustion device for garage. The gasification heat-accumulation
combustion device comprises a
water pipe wall furnace body, wherein a boiler is arranged on the
water pipe wall furnace body; an upper-layer heat-accumulation chamber and a lower-layer heat-accumulation chamber are formed in the
water pipe wall furnace body through a water
pipe partition layer; the lower-layer heat-accumulation chamber comprises a
combustion chamber and shunt-wound heat-accumulation chambers; a fire grate is arranged below the
combustion chamber, and a garbage feeding mechanism is arranged at the side part of the
combustion chamber; the shunt-wound heat-accumulation chambers include a heat-accumulation chamber A and a heat-accumulation chamber B which are communicated with each other, the heat-accumulation chamber A is communicated with the
combustion chamber, and the heat-accumulation chamber B is communicated with the upper-layer heat-accumulation chamber. According to a use method of the gasification heat-accumulation combustion device, garbage is combusted on the fire grate, and hot gas enters the shunt-wound heat-accumulation chambers through a combustion region to warm and remove impurities and simultaneously heat the water
pipe wall furnace body and the water
pipe partition layer; then hot gas enters the upper-layer heat-accumulation chamber to be subjected to heat accumulation and simultaneously heat the water pipe wall furnace body and the water pipe partition layer, and produced
waste heat is used by other equipment.
