The invention discloses a rural small multifunctional
biomass-energy heat-gas coproduction heating device. The rural small multifunctional
biomass-energy heat-gas coproduction heating device comprises a gasification furnace, a
fuel gas dewatering device, a first hot
water collection tank, a
fuel gas decoking device, a second hot
water collection tank, a kitchen hot water device, a bath hot water device, and a plurality of
water heating devices. The
fuel gas dewatering device is of a hollow box structure, and the bottom of the fuel gas
dewatering device communicates with the top of the first hot
water collection tank. The bottom of the first hot water collection tank is connected with a kitchen-bath hot water outlet
pipe, the kitchen hot water device and the bath hot water device are connected with the kitchen-bath hot water outlet
pipe after being connected in parallel, and a filter filtering device is arranged on the kitchen-bath hot water outlet
pipe. The fuel gas decoking device is of a hollow box structure. The rural small multifunctional
biomass-energy heat-gas coproduction heating device is simple in structure, a deep pit does not need to be excavated below a house foundation when the heating device is mounted, and construction is convenient. According to the rural small multifunctional biomass-energy heat-gas coproduction heating device, low-cost biomass fuel which extensively exists in rural areas can be used, clean fuel gas and hot water are produced at the same time, and thus heat-gas coproduction is achieved.
