Electrical Power from Coal Gassification

Electrical Power from Coal Gassification

Gasification of the coal basically consists of loading these small uniform pieces by conveyor onto a moving grate located about a quarter of the way up the gasifier. The gasifier is a vertical pressure vessel in which the coal is subjected firstly to high temperature in virtually anaerobic conditions in the pyrolysis stage, producing tar, coke particles, and volatiles.
