The residue that combustion zone is produced by dump grate mechanical presses, it is broken after arrange to burnt zone and burn away, treat it
Completely after burning and cooling, discharged out of the furnace by helical slag removing machine.The mixed flue gas that a combustion room is produced simultaneously enters dual firing chamber and first
High-temp combustion is carried out in Hou Ge areas thorax.Part water vapour, low boiling fuel gas from dry section, pyrolytic gasification area and
The First air introduced by burnt zone by First air intake and a main feed pipe（Combustion-supporting oxygen）Combustion zone is sent into carry out
Mixed combustion, produces substantial amounts of heat energy, and the water vapour that dry section is produced can as pyrolytic gasification area partial gasification agent.It is vertical
The type of furnace and unique air supply mode meet the temperature and reaction air capacity that rubbish needs in the crucial pyrolytic gasification stage（Oxygen deprivation
And anaerobic）Condition, and the rubbish that can react participation maintains time enough in this environment.
It can thus be seen that rubbish realizes the two-stage distribution of energy after pyrolysis in pyrolytic gasification area, pyrolysis is produced
Mixed flue gas burnt into dual firing chamber, the residue after pyrolysis burns away in the combustion zone of pyrolysis gasification furnace, the heat of rubbish
Decompose, gasify, burning is formd along the dynamic equilibrium for moving downward direction, outer with dreg removing system continuous and steady operation feeding intake

It is few, thoroughly decompose the oxious component in flue gas；
Two are, decomposed polychlorinated biphenyl material is having CuCl2, under conditions of the catalysis of C atoms, the meeting during 250-300 DEG C
Dioxin is synthesized once again, but it is indoor in a combustion, and temperature control is at 850 DEG C to 1000 DEG C, and it is in reducing atmosphere to control to oxygen amount（Anoxic
Or combustion with meagre oxygen state）, copper, aluminium, iron will not be aoxidized, and no CuO etc. is produced and be there will not be CuCl2Generation and presence, also
The catalyst for not making dioxin synthesize again（CuO、CuC12Etc. compound）, without CuCl2With the catalysis of carbon atom, dioxin
Synthesis also just without may.Pyrolytic gasification technology can also reduce NOx and SO simultaneously2Discharge because one combustion room lack
Oxygen burning category reducing atmosphere, N, S are seldom aoxidized and are left in slag.And unique dual firing chamber's design ensures that flue gas is formed
Oxygen in turbulent flow, with air is sufficiently mixed, and required air excess degree is low, correspondingly reduces the N sources from air so that
NOx discharge reductions.In addition, after pyrolytic gasification reaction, the chlorine element overwhelming majority contained in rubbish is transferred to solid product（Bottom
Slag）In so that HCl contents are far below the standard limited value of conventional domestic waste incineration in smoke evacuation.
