Coal Gasification an overview ScienceDirect Topics

Gasification of coal is a process in which coal is partially oxidated by air, oxygen, steam or carbon dioxide under controlled conditions to produce a fuel gas. The hot fuel gas is cooled in heat exchangers, with the production of steam, and cleaned before combustion in a gas turbine. The offgases from the turbine are used in a boiler to produce additional steam for a steam

CHOREN Coal Gasification

The gasification of the fuel dust is realized by partial oxidation of the coal within the entrained-flow together with oxygen and water steam at increased pressure. The carbon reacts with the oxygen to form carbon monoxide. The CCG ®-gasifier has a dust burner system optimized for maximum burnout. At the same time, the investment and operating

Gasification of Coal SAGE Journals

Coal gasification generally refers to the reaction of coal with air or oxygen and steam, to yield a gaseous product for use directly as a fuel, or as a feed to synthesis of other gaseous or liquid fuels or chemicals. Gasification in essence is an incomplete combustion. Although the physical and chemical processes are similarto the processes in coal combustion, pollutant formation
