The invention applies to the renewable energy sector, in particular to the syngas production in gasification process. Innovation in technological equipment is connected with increase of heat value of syngas and production of higher quality this flammable gas. The offered gasification unit is based on the acquisition of splitting of air flows in two or three zones in gasification process, by installation of additional air supply nozzles for air supply in secondary and/or terciary zones of pyrolysis 6 and oxidation 7.
