Abstract
An equipment for carrying out a process for producing synthesis gas (S) from biomass, includes a storage unit (1) for biomass and means (3; 5, 6) to carry out pyrolysis and combustion of the biomass. The equipment further includes first or second heat exchanging means (7, 9; 15) to receive outgoing gases (CO2, N2 and H2O) from the means (3; 5, 6) to carry out pyrolysis and combustion of the biomass, a gas purification unit (10) to receive the outgoing gases (CO2, N2 and H2O) that are cooled in the first or second heat exchanging means (7, 9; 15), means (11) to supply a process gas (P) from the gas purification unit (10) to the first heat exchanging means (7, 9), and a reduction shaft (12) to carry out reduction of the process gas (P) discharged from the first heat exchanging means (7, 9).
