Dryer section, pyrolysis section, gasification section, steam superheater provide heat, and the material outlet of the gasification section connects the combustion furnace, institute
It states pyrolysis section and the gasification section is provided with syngas outlet.
A kind of pyrolytic gasification technique, which is characterized in that it includes the following steps:
(1) material enters preheating and drying section, is preheated and is dried under the action of the heat that combustion furnace provides, generates dried object
Material and saturated steam；
(2) dried material enters pyrolysis section, and saturated steam enters steam superheater, in the effect for the heat that combustion furnace provides
Under, pyrolytic reaction generation synthesis gas occurs for the dried material into pyrolysis section and charcoal, charcoal enter gasification section, into steam superheater
Saturated steam become superheated steam, superheated steam is provided to gasification section；
(3) under the action of the heat that combustion furnace provides, gasification reaction occurs for charcoal and superheated steam into gasification section, generates conjunction
At gas and carbon residue, carbon residue enters combustion furnace as fuel combustion, provides heat for each stage of pyrolytic gasification.
After applying the present invention, the vapor that preheating and drying section generates not instead of not directly release enters synthesis gas, will
Its some or all of collection is used as gasifying medium to be used for gasification reaction using after heat, and the vapor as gasifying medium is not
It is to be generated by additional other devices, and the vapor that spent material pyrolytic gasification preheating and drying section generates is effective to recycle
The heat of material preheating and drying consumption, is used for gasification reaction, improves the material and capacity usage ratio of pyrolysis gasification system.
