Description

The biomass fuel gasifying incinerator
Technical field
The utility model relates to combustion furnace, and particularly a kind of biomass fuel gasifying incinerator is fit to the equipment use of needs heat supplies such as boiler.
Background technology
At present many users are the fuel saving expense, in the type of furnace of former burning coal, oil firing, change and burn biomass fuel (as wood fragments piece, wood chip, wood powder, the useless plate in discarded family property building site, branch etc.), send fuel mechanism that biomass fuel is directly sent into the burner hearth burning to save the price difference that burns coal, oil firing with artificial and wind.Because the ignition point of biomass fuel is lower, volatile matter is also higher, as long as keep certain temperature in the burner hearth, biomass fuel can burn.But because original type of furnace is to burn coal, oil firing, its chamber design is the condition of possibility adapted biomass fuel completing combustion not, and efficiency of combustion is very low, generally only has about 60%.And biomass fuel is failed after-flame, its emission serious environment pollution, especially its dust contained flue gas very high concentrations, have in addition stop up heating surface, need frequent blowing out deashing to handle.In the prior art, Taiwan has a producer to change the burning biomass fuel on oil burning boiler, remove fuel system, increase expansion furnace, prolong fire stroke, deliver to the burner hearth internal combustion with wind after wood chip is broken into powder, combustion efficiency makes moderate progress, but exists the obstruction smoke pipe equally, and quantity of steam will reduce problems such as 25% use, and this equipment investment is big, occupation of land is many, the preliminary treatment expense height of fuel; Germany adopts the mode of fuel system, and the wood powder after the strict processing is sprayed into the burning of oil burning boiler burner hearth with combustor, and its cost is very expensive; In the biomass gasification technology of section to the biomass material processing of will classifying, adopt fluid bed as wood chip, the wooden form of fixed bed that adopts is handled, and the carbon content of fuel, water content, shape size, inlet amount etc. all there is strict requirement, this technology is mainly used on the small-sized wood gas elelctrochemical power generation equipment, but the tar that produces in service can cause secondary pollution.Just because of the problem of above-mentioned existence, the time up to now, biomass fuel does not also obtain excellent popularization and uses, this is the deficiencies in the prior art part just.
Summary of the invention
In order to solve the problems referred to above that existing bio-fuel burner exists, the utility model provide a kind of ratio of combustion fully, the thermal efficiency is high, pollution is little, to the good and safe and reliable biomass fuel gasifying incinerator of biomass fuel adaptability.
Above-mentioned task realizes by this way: a kind of biomass fuel gasifying incinerator, comprise body of heater, furnace rake, dust collection chamber, exhaust outlet, feed well, air inlet and air blast, it is characterized in that: body of heater is horizontal, fuel Burning Room and fuel gasification chamber will be divided in lower furnace portion with a stock retaining wall before and after the burner hearth, be provided with an observation door in fuel Burning Room bottom, be provided with the fuel storage storehouse of a strap brake door in charging aperture the inner, be provided with bellows in the burner hearth rear end, air inlet is evenly opened on bellows and medial surface that burner hearth is connected, and bellows are connected with air blast.
This burner is like this work: by artificial or plant equipment biomass fuel being sent into the fuel storage logical sequence from charging spout earlier during use, to fall into fuel gasification more indoor, meanwhile, the biomass fuel that adds the less easy burning of a certain amount of volume from the observation door of fuel Burning Room toward the fuel Burning Room, biomass fuel in the first subsequently fire fuel Burning Room, make it be in the naked light fired state, then by the biomass fuel in the fire door fire fuel vaporizer.Because it is to can not get clean-burningly that biomass fuel is deposited in combustion gasification indoor, material is heated chemical reaction just takes place, and discharges unburned volatile matter (being wood gas and tar).Regulate wind supply quantity by control system this moment, these volatile matters raised deliver to fuel Burning Room top to realize fully burning under naked light, and the hot blast of generation is delivered to boiler or other need the equipment of heat supply through exhaust outlet.When this burner moves, biomass fuel is interrupted that to be added to fuel gasification from the fuel storage logical sequence indoor, and regulate air-supply and boiler air inducing and weight of material and lumpiness and make lighter biomass fuel (the wood fragments piece less) be blown into fuel Burning Room internal combustion as wood powder, wood chip and volume, constantly produce naked light, it is indoor to allow wood fragments head rest deadweight heavier or that volume is bigger fall fuel gasification, be heated and produce fuel gas and imperfect combustion thing, be blown into the fuel Burning Room with the wind and fully burn.This shows that the utility model is the light broken biomass fuel of incendivity both, can allow the biomass fuel of heavier or larger volume finish the process of pyrolysis, gasification and burning continuously again in burner hearth, this is the characteristic and the most effective part of the utility model.
The fuel storage logical sequence of this burner and the gate of feed well are carried out one open-one close or two off status when burner hearth burns, can not leak from the fuel storage logical sequence to guarantee the heat in the burner hearth.
From structure of the present utility model and operation principle thereof as can be known, this burner has been compared following advantage with existing biomass combustion device:
1, the utility model can according to biomass fuel characteristic, realize that gasification and combustion technology have complementary advantages, synchronous operation is fully burned biomass fuel, has improved the thermal efficiency greatly, cuts down the consumption of energy;
2, because biomass fuel can fully burn, do not have problems such as temperature instability, dust stratification and coking, discharged flue gas is cleaner, reduces the pollution to environment, helps environmental protection;
3, this burner is relatively good to the adaptability of biomass fuel, do not need biomass fuel is carried out the too strict classification and the preliminary treatment of lumpiness, as long as the maximum lumpiness in the biomass fuel that control mixes surpass 300 millimeters just can, thereby the disposal cost of having saved biomass fuel;
4, this burner security of operation, simple to operate is easy to maintenance, and small investment is taken up an area of and lacked, and operating cost is low, implement easily, and also easy to use.
