A gasifier operates at greater temperatures and pressures than a coal boiler — about 2,600 degrees Fahrenheit (1,427 degrees Celsius) and 1,000 pounds per square inch (6,895 kilopascals), respectively. This causes the coal to bear completely different chemical reactions. First, partial oxidation of the coal’s carbon releases heat that helps feed the gasification reactions. The first of these is pyrolysis, which occurs as coal’s risky matter degrades into a number of gases, leaving behind char, a charcoal-like substance. Then, reduction reactions transform the remaining carbon within the char to a gaseous mixture often known as syngas.
