<p>An apparatus for generating electrical and/or mechanical energy from at least a low-grade fuel comprises a closed circuit in which steam is formed in a steam boiler (10 fired with low-grade fuel, the steam formed is superheated in a superheater (5) with the aid of heat originating from a heat source (6) in which high-grade fuel is burned, the superheated steam is fed to a steam turbine (2) in which the steam is expanded, thereby delivering work, the expanded steam is condensed in a condensor (3) and the condensed steam is fed back to the steam boiler (1) via a condensate degasser (4). The combination of forming steam with the aid of heat originating from low-grade fuel and superheating said steam with the aid of heat originating from high-grade fuel provides a process for converting fuel into electrical and/or mechanical energy with a relatively high overall efficiency.</p> |
