Abstract

The invention discloses a multifunctional energy-saving biomass semi-gasification furnace capable of preventing ash accumulation. An auxiliary flue can be used for heating a heated brick bed, and a boiler can also be used as a cooking bench, so that the versatility of the boiler is realized; a heating pipe is arranged in a main smoke outlet channel, and the heating pipe is heated by utilizing thewaste heat of flue gas, so that the waste heat of the flue gas is fully utilized, and the utilization rate of the flue gas of the boiler is improved; a hearth water cooling plate is arranged to form two layers of combustion chambers, so that semi-gasification is achieved in the furnace; a secondary air damper realizes complete gasification and combustion of biomass; a grate group and a grate movable wrench are designed, so that left-right shaking of a strip-shaped grate is realized, the gap is enlarged, and the ash can conveniently fall off and is not accumulated; meanwhile, the contact area with air is increased, the fire stirring effect is started, the fuel is fully combusted, and the fuel resources are saved. The multifunctional biomass semi-gasification furnace can be used for heatinga geothermal heating heated brick bed and can also be used as a cooking bench, the utilization rate of the flue gas of the boiler can be improved, and the biomass fuel is fully combusted.

Description

technical field [0001] The invention relates to the technical field of a biomass gasification furnace, in particular to a multifunctional energy-saving biomass semi-gasification furnace capable of preventing soot accumulation. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. Boil...
