摘要

The steam generator (1) proposed uses biomass as fuel (S) to achieve particularly high efficiency. It includes a first combustion chamber (24) in which a gaseous working fluid (A) is produced by burning a first fuel (K) and a second combustion chamber (26) in which a second fuel (S) is burnt. The second combustion chamber (26) is downstream, relative to the direction of flow of the working fluid (A), from the first combustion chamber (24). The fuel (K) fed to the first combustion chamber (24) is coal and/or the fuel (S) fed to the second combustion chamber (26) is biomass, in particular straw. The working fluid (A) produced in the first combustion chamber (24) when the steam generator (1) is in operation is used as combustion air in the second combustion chamber (26).
