Solid fuel is gasified in a fixed bed at pressures of 5 to 150 bar using a gasifying agent containing oxygen, water vapor, and/or carbon dioxide. The non-combustible mineral residues remaining after gasification are discharged as liquid slag. Powdered fuel and fine-grained fuel are injected into the lower part of the fixed bed along with a carrier gas stream. The particle size of the powdered fuel and fine-grained fuel can be up to about 6 millimeters; at least 50% (by weight) of the fuel particles have a size of less than 3 millimeters. It is preferable to use a high-methane gas as the carrier gas, with at least 30% (by volume) methane contained in it. The carrier gas stream also includes methane-rich waste gases from synthesis plants, such as those from methanol or ammonia synthesis plants

The process by which solid fuel is artificially converted into combustible gas at high temperatures through the action of air, water vapor, or oxygen is called solid fuel gasification.

The process of reacting solid fuels (such as coal and coke) at high temperatures with gasifying agents (such as air, oxygen, and water vapor) to produce gas is called solid fuel gasification. 　　The raw materials used in the gasification process can be lignite, bituminous coal, anthracite, subbituminous coal, and coke, among others. The gasifying agent is oxygen or oxygen-containing compounds, such as air, water vapor, carbon dioxide, etc. The equipment used for gasification is called a gas generator or gasifier.
