Net surface, level-one igniter start to light a fire, and light biomass fuel under the action of the combustion air of combustion air fan blowout, biology
Matter fuel crushes feed appliance direction towards spiral by level-one igniter direction and successively burns, and the heat for generation of burning passes through tar mistake
Filter position enters in boiler bin, realizes a heat supply, and the tar that biomass fuel combustion generates when tar filtering cabin by passing through
The barrier of helical baffle residual titration can enter to be pyrolyzed in storehouse again, and the cigarette ash that is blown afloat through combustion air or not stopped by helical baffle
It is in negative pressure since the rotation of negative pressure fan to flow back in storehouse, negative pressure flows back storehouse again will be into when tar firmly is entered in boiler bin
Enter tar in boiler bin and ash content resorption into pyrolysis oven, part biological matter is sintered into charcoal in pyrolysis oven, opens storage at this time
The steam of sump bottom emits nozzle, sprays into a small amount of vapor into pyrolysis storehouse, the vapor and charcoal of penetrating react at high temperature
Flammable carbon monoxide and hydrogen are generated, is blown into boiler bin by combustion air fan, is lighted through secondary points firearm and carries out secondary confession
Heat, and in the hydrogen generated in being pyrolyzed storehouse electricity can also be pyrolyzed in oscillation with the tar of the residual titration from tar filtering cabin and reflux storehouse
The reaction was continued under the pyrolysis of resistance net generates flammable methane, is equally blown into boiler bin by combustion air fan, through two level
Igniter, which is lighted, carries out heat supply three times, and in be pyrolyzed storehouse, oscillation pyrolysis resistance net is vibrated in due course by a small amount of ash content of generation from shaking
It swings to shake in the hole of pyrolysis resistance net and fall, and cleared out from cleaning door, so the grease proofing of biomass boiler can be completed in cycle
Dirt sintering.
The beneficial effects of the invention are as follows：The anti-grease boiler of the present invention is divided into pyrolysis storehouse and boiler bin two parts, boiler bin
The heat and fuel received is all that by being pyrolyzed storehouse, treated, and the tar that biomass fuel combustion generates passes through tar
Residual titration can enter to be pyrolyzed in storehouse again by the barrier of helical baffle when filtering cabin, and the cigarette ash that is blown afloat through combustion air or not by
When the tar that helical baffle stops is entered in boiler bin, since the rotation of negative pressure fan in reflux storehouse to be in negative pressure, negative pressure
The tar entered in boiler bin and ash content resorption are further pyrolyzed heat production by reflux storehouse into pyrolysis oven again, will not be sent out in boiler bin
Raw scale formation, and the good antiscale property boiler of the present invention have passed through three-level sintering so that and biomass fuel is fired close to completely burned
85% can be reached by burning efficiency, and the sintering efficiency compared to traditional biomass boiler improves 22%, and ash after incineration only has 1.5
~2.0%, clean and effective has broad application prospects.
