Abstract
The utility model provides a household biomass gasification furnace, wherein the fire box is charged with the biomass fuel through a charging hole or the upper part of a burner, the biomass fuel is ignited from the top and starts to flame; at this point, the oxygen needed by the combustion of the biomass is supplied through an air inlet chamber arranged below a furnace bridge, the combustion state of the biomass is controlled by regulating the air output quantity in the air inlet chamber, which makes the biomass reach the gasification state; because the specific gravity of the flammable gas generated by the biomass is relatively small, the flammable gas flows upward under the action of other gases in the furnace and mixes with the air inputted from an air inlet pipe of the burner in one end of the burner, of which the diameter is relatively small, and flames; during the use, only by regulating the height of the furnace bridge and the air output quantity in the air inlet chamber, the effective gasification of the biomass fuel and the sufficient combustion of the flammable gas are guaranteed; obviously, the household biomass gasification furnace of the utility model does not need to collect, purify and convey the flammable gas generated by the combustion and gasification of the biomass, thereby resolving the tar treatment problem and overcoming the defect existing in prior art; moreover, the household biomass gasification furnace of the utility model is simple in function, and a user can know how to operate even at a glance, as a result, the utility model is called as the 'fool' household biomass gasification furnace.
Description
Technical field
The utility model relates to domestic biomass gasification stove because the utility model domestic biomass gasification stove operation is very easy, at a glance can, therefore, be called as " fool " domestic biomass gasification stove.
Background technology
Domestic biomass gasification stove is to utilize living beings (as: agricultural waste material such as stalk, rice husk, branch, weeds or house refuse etc.) to burn under anaerobic condition, make most of combustible species be converted into fuel gas, through cooling, purify after for uses such as cooking, heatings.Common household gasification furnace comprises updraft type fixed-bed gasification furnace and downdraft fixed-bed gasification furnace.Updraft type fixed-bed gasification furnace basic structure is a cylindrical furnace, is lined with refractory material at inboard wall of furnace body, and the body of heater bottom is connected with air intake pipe, and upper of furnace body has the sealing loam cake.During use living beings are put into body of heater, the igniting airtight burning in back is only carried air by air blast in body of heater, and the control air input just can guarantee the anoxycausis of living beings, generates fuel gas.Top at body of heater is provided with the fuel gas gathering-device usually, and the pipeline of outside transporting combustible gases is arranged.At present, household gasification furnace mostly is a split-type structural, be that gasification furnace separates with burner, after gasification furnace is collected the fuel gas of living beings gasification back formation, be transported to cooling device, filter or tar separation device etc. by pipeline, to remove dust in the fuel gas, tar etc., be transported to burner combustion again.And the most unmanageable in this course of conveying be exactly tar in the combustion gas, higher because of its content, in course of conveying, may be deposited in pipeline or cooling device and the filter, cause gas pipeline or device to block, form secondary pollution or the like.In addition,, then may cause fuel gases calorific value lower if tar separation is not thorough, can not effective use of energy sources, phenomenons such as burner collection charcoal obstruction.Therefore, the tar content that how to reduce in the household gasification furnace combustion gas becomes the important topic that it is promoted the use of.
The fuel gas that above-mentioned domestic biomass gasification stove produced need be collected and carry, and therefore, structure is comparatively complicated.And, limited the domestic biomass gasification stove promotion and application to a great extent because the existence of tar makes that collection, purification and the conveying of fuel gas are more complicated and difficult.
Summary of the invention
