ABSTRACT:
A steam generator achieves an especially high efficiency when biomass is used as a fuel. The steam generator contains a first combustion chamber for generating a gaseous working medium by burning a first fuel and a second combustion chamber for burning a second fuel. The second combustion chamber is connected downstream of the first combustion chamber in flow direction of the working medium. Bituminous coal may be fed as the first fuel to the first combustion chamber and/or biomass, in particular straw, may be fed as the second fuel to the second combustion chamber. The working medium generated in the first combustion chamber during operation of the steam generator serves as combustion air in the second combustion chamber.
