two-stage coal gasifier

Abstract of coal gasifier

Double stage coal gasifier is a coal gasification equipment include dry distilation section and gasification section.

It use 40/60mm bitumious coal as raw material,and dry distillation process occurs in the upperstage of the gasifier,then carbocoal is generated and go in to the lower stage of the gasifier for gasification process.The dry distillation and gasification process are finished in the gasifier,and coal gas go through a series of processing steps like dust removal,detarring,cooling and sulpher removal by after treatment equipment.

The purified coal gas is then pressurized and transferred to industrial stoves to use as fuel.Depends on the coal gas quality requirement for different stoves,double stage cold gas station can have double stage hot gas station with electrie detarring precipitator and double stage cold gas station.

The whole system include the coal lifeing system,coal adding system,air supply system,gasification system,dust removel system,cooling system,sulphur removel system,deterring precipitation and collection system,phenol water disposal and inclneration system,automatic control system,gas storage and pressurized gas transfer system.
