Role of Gasifier in Gasification

Gasifier is the heart and soul of a gasification process. The equipment converts haydrocarbon

feedstock into gaseous components. The conversion takes place by applying heat under pressure in presence of steam. 

It is often seen that people get confused between gasifier and combuster. In case of gasifier, there is limited supply of oxygen inside the equipment so that only certain amount of fuel burns completely. The partial oxidation process provides heat. Instead of complete burning, most of the carbon containing feed material is chemically broken apart by the gasifier's heat and pressure, setting into motion chemical reactions that produce syngas. 

In Gasifier, the carbon dioxide produced by the process is in a concentrated gas steam, making it easier and less expensive to separate and capture.
