Entrained-flow gasifier is the most successful and widely used type of gasifier for large-scale gasification of coal, petroleum coke, and refinery residues. Entrained-flow gasifier is ideally suited to most types of coal except low-rank coal, which, like lignite and biomass, is not attractive because of its large moisture content.

Coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and …

In conventional power plants, coal is burned in order to heat water to drive steam turbine-generators. Only about 30 percent of the coal's energy value actually winds up producing electricity; the rest is waste heat. By using what's called a combined cycle to produce electricity, gasification plants can ratchet efficiency up to 50 percent or more.
