（27）Reducing zone is sent by the round tangential air-supply arrangement (22) in reducing zone after waste-heat, as auxiliary gasifying agent；
(3) material gradually decreases down cracking zone by furnace roof dry section, and part flow arrangement is isolated through Y types cracking gas in the gas for cracking generation
(19) above circular hole (19-3) into the interlayer between the device and zoneofoxidation internal protecting wall, not with zoneofoxidation gas, biology
Matter haptoreaction simultaneously tentatively enters reducing zone under the premise of cracking；
(4) combustion gas of zoneofoxidation generation mainly includes the various combustible components such as hydrogen, carbon monoxide, hydrocarbon, tar, with
And unreacted partial oxidation, the carbon dioxide etc. of generation, combustion gas gasify with half after residual coke downwards through upper moving grate (21)
Into reducing zone, residual burnt, combustion gas and the vapor generation reduction reaction for being passed through the area；
(5) gas-solid product passes through lower moving grate (24) downwards, and the tar in combustion gas further decomposes in high-temp solid residue
For gaseous state combustible, solid is residual burnt into ash entrance chamber (27), heats the indoor layer chuck (29) of ash, the vapor in outer layer chuck (28)
And oxygen, gas are upwardly into furnace wall chuck (16) through the isometrical furnace wall jacket inlet (25) above grey room (27), tar is into one
It walks by Pintsch process, and under Irregular shield (18) effect of furnace wall chuck (16) interior welds, in dust and remaining tar
Big drop removed by inertia force, combustion gas is finally brought out through the air accumulator interface (17) above chuck outside stove；
(6) when the residue accumulation in grey room (27) is more, ensuring upper movable flashboard (11) closing above grey room (27), master
Under the premise of reactor is gastight, the lower movable flashboard (12) below grey room (27) is opened, residue is discharged out of the furnace.
