Gasification agent

In order to convert solid biomass into inflammable gas, a substance to promote the chemical reaction is necessary. This substance is called the gasification agent, and mainly air (N2, O2), oxygen (O2), H2O, or CO2 are applied as an appropriate mixture. Air (only O2 reacts) and O2 generate heat by oxidation, and increased O2 decreases the effective amount of inflammable gas.
