ABSTRACT:
The invention concerns a combined gas-turbine and steam-turbine power plant, which comprises heat transfer members which interconnect a pressurized dryer (26) and waste-heat recovery members (22), by means of which the recovered thermal energy of the exhaust gases from the gas turbine (20) can be transferred directly or through the steam turbine into the dryer (26) for the drying of a water-containing material, advantageously fuel, and for the passing of the steam produced as injection steam to the gas turbine (20). The invention also concerns a method for improving the efficiency of a power-plant process.
