Abstract (en)

Method to produce a product gas with low tar and dust contents from solid biomass, biogenic residues and/or organic waste fractions with a gas production device (100), the gas production device (100) comprising: a fuel conversion reactor (1a, 1b), which is an updraft gasification reactor (1a) or a pyrolysis reactor (1b); and a gas treatment reactor (2) located downstream the fuel conversion reactor (1a, 1b); wherein the fuel conversion reactor (1a, 1b) is close-coupled with the gas treatment reactor (2); wherein the fuel conversion reactor (1a, 1b) comprises a space to contain a fuel bed (3) above a grate (4); wherein the gas treatment reactor (2) comprises the following: a POX zone (12), and at least one POX nozzle (22) for supplying an oxidiser into the POX zone (12); and a gas heating zone (10) fluidic located between the space to contain the fuel bed (3) and the POX zone (12); wherein the method comprises the following steps: Creating an initial product gas (VI) in the fuel conversion reactor (1a, 1b); Heating the initial product gas, which is created in the fuel conversion reactor (1a, 1b), in the gas heating zone (10); Combusting the heated initial product gas in the gas treatment reactor (2) partially in the POX zone (12) of the gas treatment reactor (2) by injecting or supplying an oxidiser through the POX nozzles (22) into the POX zone (12).
