BIOMASS GASIFICATION SYSTEM AND METHOD, FOR THE PRODUCTION OF COMBUSTIBLE GAS

摘要

A method and a system (1) for the gasification of biomasses for the production of combustible gas are described. The system comprises a fixed-bed gasifier (10) in which the biomass undergoes a controlled combustion in oxygen deficiency, which provides sufficient energy to trigger a pyrolysis process in which the tars contained in the biomass come to the boil, releasing hydrocarbons and combustible gases, so as to obtain a gaseous fuel. The system (1) comprises oxygen supply means (2) to feed air enriched with oxygen (O2) into the gasifier (10) to promote the controlled combustion of the biomass and to obtain a combustible gas having a greater heating value.
