Abstract
A method for controlling the output composition from a gasification device for use in the gasification of biomass using a gasifier in which the biomass and gas both flow in a downward direction. The method combines the use of steam and oxygen as a mixed oxidation stream to control the processes occurring within the gasifier. The oxidants are introduced into the gasifier using a number of injection rings. Each injection ring is comprised of a number of injection nozzles each radially distributed at the same vertical height and possibly connected to the same supply source. Particularly satisfactory results can be achieved through the use of three injection rings, one at the top of the gasifier, one at the interface of the oxidation and reduction zone and one a small distance below the grate assembly. The produced syngas also contains extremely low concentrations of tar and low molecular weight hydrocarbons.
