Integrated gasification combined cycle - Wikipedia
An integrated gasification combined cycle (IGCC) is a technology that uses a high pressure gasifier to turn coal and other carbon based fuels into pressurized gas—synthesis gas ()It can then remove impurities from the syngas prior to the power generation cycle Some of these pollutants, such as sulfur, can be turned into re-usable byproducts through the Claus process

Gasification as incomplete combustion Gasification is most simply thought of as choked combustion or incomplete combustion It is burning solid fuels like wood or coal without enough air to complete combustion, so the output gas still has combustion potential The unburned gas is then piped away to burn elsewhere as needed Gas produced by this method goes by a variety of names: wood gas .
