Coal fleet age distribution. Each of the 1,105 individual coal-fired units was placed into a five-year age category. For example, the category “5” represents plants that are 5 years old or less. The category “10” represents plants that are more than 5 and less than or equal to 10 years old.

Chemistry of coal gasification (Conference) OSTI.GOV

Gasification is the conversion of solid coal to combustible gases by combining the carbon with additional oxygen and/or hydrogen. Although thermal decomposition (pyrolysis) can produce gaseous fuels, they are usually produced by reaction with oxygen, hydrogen, steam and carbon dioxide.

Coal Gasification and Its Applications ScienceDirect

Underground coal gasification (UCG) involves the unmined coal seams that are reacted underground, with insufficient oxygen for complete combustion, to create syngas. An oxidant, usually air, flows through an injection well and into a cavity in a coal seam. The oxygen and water within the coal seam react with the coal to produce syngas, which is

Coal Gasification Encyclopedia

2021-1-13  Coal gasification The term coal gasification refers to any process by which coal is converted into some gaseous form that can then be burned as a fuel. Coal gasification technology was relatively well known before World War II, but it fell out of favor after the war because of the low cost of oil and natural gas .
