Description
Technical field
The utility model is related to a kind of kitchen range, particularly to a kind of gas with the biomass material such as fuel wood and stalk as fuel
Change combustion stove.
Background technology
China is large agricultural country, has the biomass energies such as fuel wood and the stalk of abundance, in the exploitation of biomass energy
In, conventional mode is direct combustion or gasifying electricity generation, but, need when direct combustion uses often to add fuel wood to cooking stove, using not side
Just, gasifying electricity generation is limited to cost, and economic benefit is not good, and cannot large-scale promotion application.
Traditional cooking stove is with a long history to fuel wood and straw utilization, and traditional cooking stove is because using inconvenience, utilization rate of heat value is low, typically
Only 15% to 20%, big to air pollution.Also gradually abandon in vast rural area, lead to the exploitation amount of biomass energy more next
Less it is impossible to reproducible fuel wood and stalk are effectively utilized in a large number in rural area.
For this reason, the living beings such as fuel wood and stalk are carried out be gasificated into the small-sized biomass downdraft gasification device of combustible gas
Stove core structure arises at the historic moment, and people have invented the uniflow gas stove stove inhaling the combustion gas of generation upwards, but, the gas of updraft type
Change cooking stove and there are some defects：(1) tar content is high, leading to cooking range capable of gasifying short life it is simply that increasing filter, dimension occurs again
The difficult problem of shield；(2) aerogenesis is unstable, and the gasification of living beings is difficult to control to, and leverages the popularization of cooking range capable of gasifying；(3) produce
Gas calorific value is low, and gasification of biomass not fully leads to aerogenesis calorific value not reach routine use requirement.
For this reason, inventor invented the applying date be 2011.11.11, Patent No. CN201120444716.2, entitled
The gasification, and combustion cooking stove of " a kind of Household biomass fuel-efficient stove ".It is included feed bin, is provided with the gas being connected with feed bin below feed bin
Change combustion chamber, the ash-falling chamber connecting under gasification furnace core and with gasification furnace core, and be provided with ash-falling chamber side and connected by conduit
Vigorous fire kitchen range, wherein feed bin include upper and lower opening warehouse, on warehouse upper opening material lid, warehouse surrounding blast pipe
With smoke exhaust pipe it is characterised in that described gasification furnace core include connecting with feed bin lower opening aditus laryngis, aditus laryngis minimum bit
Gasification air intake nozzle is assembled in the cincture that the place of putting is provided with, and the gasification reactor chamber in the middle part of gasification furnace core；Described gasifies around gathering
Air intake nozzle is to tilt 45 degree to be arranged on aditus laryngis, and described is additionally provided with to around poly- on gathering gasification air intake nozzle side
The blower fan of collection gasification air intake nozzle air intake, is provided with the water tank of the waste heat using gasification furnace core gasification reaction in gasification furnace core periphery,
And it is provided with spiral heat exchanger fin between water tank and gasification furnace core, described ash-falling chamber includes ash-pan；Described warehouse lower opening
Being provided with to control fuel to fall and pieced together by two sectors makes fuel intercept, with gasification reactor chamber, the temperature reducing feed bin
Feed bin door.But in the follow-up development of inventor, find that the structure design of gasification furnace core has some as gasification furnace core guarantor
Warm poor performance, anti-poor performance of expanding with heat and contract with cold, gasification not exclusively, the defect such as tar fails all to remove, cause fuel wood and stalk etc.
Biomass fuel aerogenesis is stablized undesirable.
For this reason, inventor improves again, Application No. 201510072598X, a kind of entitled " biology are applied for
The patent of matter gasification stove combustion chamber structure ", its feature be gasification furnace core inside and outside wall between be provided with heat-insulation layer；Inside gasification furnace core
