Downdraft Gasifier. Biomass gasification consists in the decomposition of a solid, for example, wood, by a reactive gas, for example, air, to obtain a gaseous fuel. During this process, biomass is subjected to four successive thermochemical phenomena: drying, pyrolysis, oxidation, and reduction. Drying: The fuel moisture is removed by evaporation.
