Household biomass gasifier

Abstract

The invention relates to a household biomass gasifier comprising a gasifier body, an AC / DC variable speed blower and a fuel gas burner, wherein the furnace body converts fuels into combustible gas with a low heat value, the AC / DC variable speed blower sends air into the furnace body, and the fuel gas burner burns the combustible gas for heat supply; the blower is provided with two air outlet pipelines, wherein one air outlet pipeline is led to the position below a grate bar at the lower part of the gasifier body, the air is sent to a gasification chamber through a plurality of air inlet holes on the grate bar, and the other air outlet pipeline is connected to the rear ends of two-stage purifying devices through air distribution pipelines and is connected with a combustible gas transmission pipe; a fuel gasification chamber at the upper part in the gasifier is connected with the two-stage purifying devices through air output pipes, the combustible gas processed through a first-stage purifying device and a second-stage purifying device and the air transmitted through the blower are mixed at the rear end of the second-stage purifying device for forcible air distribution, wherein the air distribution volume is that 15-20 percent of air is mixed into 1m<3> of combustible gas, and the mixed combustible gas enters a core inside the fuel gas burner in a tangential direction through a mixed fuel gas inlet pipeline; and the gasifier has the advantages of multiple fuels, easy operation and environmental protection.

Description

Technical field: [0001] The invention relates to a household type biomass gasifier. Background technique: [0002] At present, although the existing coal gasifiers and biomass gasifiers can provide coal gas and biomass gas, the types of fuel are single, the purpose is narrow and the gas production is small, it is difficult to ignite, the operation is difficult, and it cannot be used during power outages. A large amount of tar will be produced, which will cause serious environmental pollution. The tar will also damage the furnace itself, and the household biomass gasifier does not have a dedicated burner. The burners used in the current household biomass gasifier are generally for pipeline gas , liquefied petroleum gas, natural gas and other high calorific value gases, the pipes and burners are often blocked by tar during use, which is not conducive to maintenance, short service life, and the air intake and air ratio are not suitable for household biomass gasification Theref...
