ABSTRACT:
This publication discloses a method and an apparatus for the utilization of the heat value of a water-bearing fuel in a gas turbine power plant. The apparatus comprises a high-pressure combustion unit (7), a gas turbine (15), a generator (16), and heat recovery units, the latter connected the system close to the gas turbine (15) outlet. According to the invention the water-bearing fuel is dried in a high pressure by the heat energy of the turbine exhaust gases, and the steam generated in the dryer stage is fed to the high-pressure section of the combustion process, at a point between a compressor (9) and the turbine (15), that is, for instance, into the combustion or gasification unit (7). The system in accordance with the invention provides for the utilization of the heat value of fuels having a high moisture content.
