METHOD FOR BIOMASS GASIFICATION IN A FLUIDIZED BED

摘要

The invention relates to a method for the gasification of a biomass in a fluidized bed, wherein the biomass is first pre-dried and fed to the fluidized bed gasifier, the raw gas from the gasifier then charges a recycling cyclone and subsequently at least one raw gas cooler. The aim of the invention is to improve the yield of such a process and lower the initial cost. This is achieved by the fact that the dusts forming in the hot-gas filter mounted downstream of the raw gas cooler are fed back into the inlet system of the biomass.
