During use of the direct-fired biomass gasification furnace, a secondary air supply can be delivered into the combustor on the upper portion of the furnace body, the combustible gas can be gathered to the co-burner of the combustor and then combusted, the combustion flame of the combustible gas is centralized, the firepower is strong, and the heat is released in a centralized mode and is easy to be absorbed and utilized by cookers with a high utilization rate.
Description
Technical field
The utility model relates to solid-fuelled domestic burners such as a kind of employing bavin, coal, specifically relates to a kind of direct-fired biomass gasification furnace.
Background technology
In the known technology; The tar that produces in the biomass gasifying furnace course of work gathers easily and stops up appendix and burner, and for the technical solution problem, the technical scheme that has adopts the cancellation appendix; The combustion chamber is set above vaporizer, and the combustible gas that vaporizer is seen off carries out the direct combustion processing.Like publication number is the patent documentation of CN201368484; A kind of new improved faggot gasification air return stove is disclosed; Comprise furnace shell and core body; Also comprise a stripper loop, said stripper loop is separated into the annular return air chamber on top and the annular secondary air feed chamber of bottom with the toroidal cavity between furnace shell and the core body, and said core body is provided with the secondary air hole; Said core body upper periphery is provided with a connecting ring seat with first interface, and the interior collar extension of said stripper loop is provided with second interface that is complementary with first interface.But this technical scheme remains the deficiency aspect two, the one, and the flame that the combustible gas burning produces is wide, and firepower disperses, and the heat utilization ratio of cooker is not high; The 2nd, it is excessive that the oxygen supply of vaporizer is prone to, and causes combustible gas burning in advance in the system air chamber, and the flame of generation is low, and flame envelope can't arrive the cooker bottom, and heat utilization ratio is low.
Summary of the invention
The utility model provides a kind of direct-fired biomass gasification furnace, can make combustible gas gather cooker bottom concentrated combustion, and the firepower of generation is big, and heat utilization ratio is high.
The technical scheme that the utility model adopts is: a kind of direct-fired biomass gasification furnace; Comprise body of heater, blower fan and adjusting valve, upper of furnace body is provided with the combustion chamber, and the body of heater bottom is provided with vaporizer; Mixed burner is set between combustion chamber and the vaporizer; Vaporizer is communicated with the combustion chamber through the combustion mouth that gathers that mixes burner, mixes on the burner wind hole is set, and wind aperture secondary air road is communicated with adjusting valve.
The air-flow that blower fan produces is after adjusting valve distributes, and a part is sent into vaporizer through main air duct, and another part is sent into through the secondary air road and mixed in the burner; The combustible gas that produces in the vaporizer, with after the air of secondary air mixes, from gathering combustion mouth ejection concentrated combustion, the flame of generation is concentrated in mixing burner, and flame envelope can gather the cooker bottom, and firepower is big, the heat utilization ratio height; Secondary air is admitted to vaporizer top and mixes in the burner; The air of sending into is difficult to backflow downwards to vaporizer; Then the oxygen content in the vaporizer is difficult for excessively, and combustible gas is difficult to burn in advance at vaporizer, and major part is pushed to gathers the place's concentrated combustion of combustion mouth; The heat that produces is prone to absorbed by cooker, and heat utilization ratio is high.
Above-mentioned mixed burner comprises base plate and the shelf that is nested in upper and lower of mozzle respectively, a plurality of wind of mozzle middle part annular spread hole, and the mozzle upper end is provided with gathers the combustion mouth, and gathering the combustion mouth is both ends open and up-small and down-big ducted body.Said base plate sealing covers the vaporizer port, and the combustible gas in the vaporizer can only upwards be flowed out from mozzle; Described shelf is positioned at combustion chamber bottom, and the air of secondary air is got in the mozzle by the wind hole, mixes with combustible gas in the mozzle, and the mixed combustible gas of formation upwards flows, and gets into to gather the combustion mouth and spray concentrated combustion from open upper end.
Above-mentioned vaporizer is provided with and is communicated with outside charge door.Can be under the situation of interrupt cooking not, convenient vaporizer is added biomass fuel, improve gasification furnace continuous operation ability.
The tail gas of above-mentioned combustion chamber enters the waste heat chamber, the indoor reservoir that is provided with of waste heat.The tail gas that discharge the combustion chamber is introduced the waste heat chamber, utilize the waste heat of tail gas, the water in the reservoir is heated, to satisfy living needs.
The utility model is through in the mixed burner of the secondary air feed being sent into vaporizer top, and with combustible gas focus on mix burner gather the place's burning of combustion mouth, the combustion flame of combustible gas is concentrated; Firepower is big; Heat is concentrated and is discharged, and is prone to absorbed by cooker, and heat utilization ratio is high.
