Gasification - an overview | ScienceDirect Topics
Gasification of coal is a well-understood process, occurring as an intermediate stage in most modern coal power plants. IGCC coal plants gasify coal prior to combustion in gas turbines and recovery of waste heat via steam turbines, resulting in increased efficiencies compared with burning solid fuel in conventional boilers.

Draft Guidelines for the Assessment of Former Gasworks Sites
Coal carbonisation consisted of heating crushed bituminous coal in a sealed, oxygen-deficient chamber (the retort). This process caused coal to decompose into gas, coke, tar and ammonia. These components were then processed in various sections of the gasworks, as shown in Figure 1 (opposite). The main steps in the coal carbonisation process were:
