The combustion gasification process of the combustion gasification stove of this incineration firing gasification installation is as follows:

According to the air quantity of one, two, three air inlet of combustion case timely adjustment, supply with the air of limiting the quantity of in stove during the operation of this incineration firing gasification installation, the speed and the scope of control incineration firing form the anoxycausis state.After rubbish was lighted, primary air entered fire-through passage through air inlet, a fence, participated in burning with higher speed, made that moisture content is many, calorific value is high, the rubbish of complicated component, went up fire burns rapidly, and the temperature of fire-through passage and burner hearth is rising rapidly also.The primary air that enters flows in fire-through passage draft direction, and the speed and the scope of control incineration firing.Its burning is mainly carried out around each fire-through passage, and then extended, and make it prolong burning time as far as possible, form the anoxic reducing environment.Thereby the rubbish around the fence can very fast in the short period of time after-flame or is enlarged combustion range, unlikely the oxidation gasification appears being unfavorable for burn, burn phenomenons such as sky, perforation, Tower Bridge.

Rubbish around the fire-through passage is when burning, and the heat that burning produces constantly transmits and radiation around burner hearth, make burner and burner hearth from the middle part to the bottom again the temperature to the rubbish on top raise rapidly.Because the rubbish that is installed in of burner hearth is many, thickness is big, the sealed again and secluding air of burner hearth is so rubbish has adequate time evaporation, drying, destructive distillation, pyrolysis in whole burner hearth scope.Along with calory burning transmits continuously, radiation, make many, the organic many rubbish of water content under the reducing atmosphere environment of high temperature anoxic, the steam of overflowing gradually, fugitive constituent, and then generation destructive distillation thermal decomposition, produce a large amount of by fuel gas, steam, tar, the air mixture that flue gas etc. are formed.This process is constantly carried out, until rubbish finally become by destructive distillation carbon residue and collapse downwards fall in the slag chamber after, new rubbish replenishes into again continuously.In the combustion process of rubbish, the auxiliary air of limiting the quantity of and entering from the secondary air mouth as gasifying agent and red-hot carbon residue reaction, is kept and the combustion gasification process of stable rubbish.A large amount of fuel gas that close that mix that burner hearth produces enter whirlwind injection trunnion under the draft effect of combustion-gas flow.When the area of passage of whirlwind injection trunnion during much smaller than the area of passage of the hybrid chamber of burner, air mixture by the whirlwind groove in the whirlwind injection trunnion reverse the guiding become the air mixture of rotation after, enter the hybrid chamber of burner, mix with the tertiary air that enters from three air inlets, burner rotary combustion on the hybrid chamber top becomes cyclone type flame.Simultaneously, because the caliber of whirlwind injection trunnion is little, flow is also little, the time of staying of air mixture in burner hearth is longer, steam in the burner hearth, carbon dioxide and the air of coming in from the secondary air mouth etc. are as the red-hot carbon of gasifying agent and burning, and the carbon residue of fast after-flame, the tar of suspension etc. are the generation reduction fully.Be reduced into carbon monoxide and hydrogen as steam, carbon dioxide is reduced into carbon monoxide, and tar is broken down into hydrocarbon etc.And the not comburant in the air mixture can rest in the burner hearth for a long time as carbon dioxide, nitrogen oxide etc., makes the heat of taking away with burning few.Secondly, the tar in the air mixture and suspension carbon granules etc. also significantly reduces because of reduction reaction.Moreover, in whirlwind injection trunnion air mixture because of fast rotational makes residual oxious components such as suspension carbon granules, tar, heavy metal steam, flue dust and dioxin particulate wherein, come out by centrifugation, fall into burner hearth again, be decomposed once more the gasification or burn.

Air mixture is behind the burner rotary combustion, produce the flue gas (more than 1000 degree) of extreme temperatures, high-temperature flue gas is at the bigger burner hearth of volume, by short stay (greater than 2 seconds), particulates such as the above-mentioned tar that does not thoroughly burn, heavy metal steam, flue dust, dioxin are wiped out burn.After the high-temperature flue gas short stay, enter flue tube.When feed pipe places flue tube, in addition when feed pipe is provided with heat absorbing sheet, rubbish in the feed pipe is by the heat preheating of high-temperature flue gas, thereby the most of organic matter in the rubbish, as useless mould, evaporation drying and destructive distillation thermal decompositions such as scrap rubber, waste paper, wood chip, grease, resin, pericarp, leftovers, pyrolysis becomes fuel gas and carbon granules, when when upper of furnace body is provided with coolant jacket, after fuel gas is condensed, obtain fuel oil and combustion gas, become useful resources, and the carbon granules in the fuel gas falls to the gasification that burns away in the stove.Owing to be provided with cracker, distributing device, agitator in the burner hearth, at first the cracker that is rotated of rubbish of bulk rubbish or coking knot cake is broken into fritter, after falling into burner hearth, evenly distributed by distributing device again, and be unlikely cause leave a blank, Tower Bridge etc. is unfavorable for the phenomenon that gasifies.When these by the rubbish residue of destructive distillation, pyrolysis, when falling into lower furnace portion, be stirred that device stirs, loose, upset, not only with the mixed accelerated combustion gasification of air, and more prevented these rubbish residue cokings knot cakes, and influenced whole gasification, and combustion.

Slag behind the incineration firing, in slag chamber, slag reducing whereabouts, the unburnt carbon residue of minority in the slag by from cooling off the air that inlet pipe enters down, blows combustion and once more up to firing into ash.The hot igloss amount that makes incineration firing is very low and minimizing is very high.

The combustible gas of combustion gasification stove output obtains rough fuel oil through sending into condenser through condensation, is stored in oil storage.And fail the combustion gas composition of condensation in the combustible gas, through the output of combustion gas efferent duct or be stored in the gas holder standby.
