Device for producing a product gas from biomass

摘要

A device for producing a product gas from biomass includes a reactor which is delimited by a base part and reactor walls. The reactor walls include a circumferential wall and an upper wall. The reactor includes a supply opening for the supplying of biomass, and also at least one riser for the chemical conversion of supplied biomass to a product gas and a solid substance. The riser is attached within the circumferential wall and includes an upper end and a lower end. The reactor also has a discharge opening for the discharging of the product gas. The riser is fastened to at least one reactor wall. The base wall of the reactor has a through-opening through which the lower end of the riser movably extends.
