Description

Wood chip burner

Technical field

the invention belongs to stove and accessory technical field, be specifically related to a kind of wood chip burner.

Background technology

above mentioned wood chip mainly refers to the wood sawdust that woodwork production industry produces, but also such as straw, wheat straw, maize straw, broomcorn straw, soybean stalk and/or cotton stalk can be crushed to the biological straw wood chaff material of wood chip degree, i.e. living beings wood chaff material.

known situation is: the resource that coal, oil and natural gas etc. are non-renewable on the one hand causes price to improve constantly because of increasingly in short supply, and the nervous psychology that the mankind rely on natural resources because the plan temporarily without desirable reply causes and sense of crisis are increasingly sharpened; Utilized biomass energies a large amount of is on the other hand by serious waste.Here said available biomass energy is main but be not limited to above mentioned as rice chaff, straw, wheat straw, maize straw, soybean stalk, jowar stalk and wood chip etc.Especially in rural area, people see the phenomenon of peasant's crop straw burning every now and then, not only undermine environment, and waste resource.Although government and agricultural experts endeavour to advocate peasant by straw-returning, produce little effect.

not accommodating doubtful, the peasant in rural area always has the tradition virtue that Frugality and industry is born hardships and stood hard work, and the caving-in bash belonging in fact and doing something against one's will of why fuel wood being committed to the flames, reason roughly has be the fuel value of farmers' bio-fuel low at four: one, use this fuel can extend undoubtedly and cook the meal time, and Fuel Consumption is superfluous, deficiency thinks that the daily meal that does consumed; Two is lack rational stove and accessory; Three be difficult to directly by industry and business as fuel; Four is collect that cost of transportation is large and price is meagre.

although can play the effect of protection non-renewable resources to the energy exploitation and application of inexhaustible water energy, wind energy and solar energy and so on, because of the restriction by geographical position, this energy only can prove effective in limited area.

in above mentioned four reasons; suitable stove and accessory is the key factor solving biomass energy outlet; because; if there be a kind of biomass fuel can being converted into be suitable for the energy that is industrial and business use; so certainly can play and both save and protected non-renewable resource, can be the effect that this double gain falls in industry and commerce for increasing peasant income again.

biological fuel gasification furnace can by biomass fuel as generated CO(carbon monoxide after straw drying, cracking (pyrolysis), oxidation and reduction) the gas device that supplies such as boiler and so on uses.Such device can be seen in Chinese patent literature, typically as the biological gasification furnace of Chinese invention patent notification number CN101531925B recommendation, this patent formula has the technique effect alleged by Instructions Page 2 the 20 to 22 row, and for example invention patent mandate notification number CN102268298B " Downdraft biomass fuel gasifier " that provide, this patent formula compensate for the shortcoming of aforementioned CN101531925B, the objective technique effect embodied in the technique effect hurdle of description.

but, the patent formula being not limited to exemplify above is not suitable for aforementioned biological matter wood chaff fuel, because living beings wood chaff fuel without the need to through super-dry, split that (heat) separates, oxidation and reduce and can directly burn, for the device of such as heat blower and boiler and so on provides the energy.Living beings wood chaff fuel economy is cheap, and such as the price of diesel oil is 9-10 unit/kg at present, and the price of living beings wood chaff fuel is only 0.25-0.35 unit/kg, is 1/10th of diesel oil cost.Particularly living beings wood chaff fuel has the strong points such as efficiency of combustion is high, caloric value is large, burning-point is low, it is high to generate heat, and the sulfur dioxide produced during burning, ammonia nitriding compound and dust are few and is acknowledged as the New-type fuel of high-efficiency environment friendly.But, all technical information being suitable for stove and accessory to the fuel combustion of living beings wood chaff are showed no in disclosed patent up to now and non-patent literature, the applicant has done positive and useful design for this reason, finally technical scheme described below is defined, and carried out simulated test in the applicant plant area taking under strict secrecy provision, result proves not only safety but also practicable.
