US 5,111,662 A · Gas/steam power station plant

Abstract

In a gas/steam power station plant, which consists essentially of at least one fossil-fired internal combustion engine (2), at least one steam circuit (1) and at least one heat exchanger (3), the heat exchanger (3) connected downstream of the internal combustion engine (2) is fed with exhaust gases (27) from the internal combustion engine (2). Together with a number of steam turbines (12, 13), the steam circuit 1 has a generator (14), a series of other auxiliary units (15, 16) and a water-cooled reactor (11) which produces an amount of saturated steam (B) from an amount of preheated feed water (C) treated in the heat exchanger (3) and fed to it. This amount of saturated steam is thereupon fed to a superheat stage (A) in the heat exchanger (3), where the actual final treatment of the steam takes place.

Dependent claims

A gas/steam power station plant comprising:

at least one fossil fuel circuit producing electric power and at least one steam circuit producing electric power;
said fossil fuel circuit having turbine means receiving combustion gases for operating an electric generator;
said steam circuit having reactor means for producing saturated steam from feed water and turbine means receiving said saturated steam for operating an electric generator;
at least one heat exchanger means for heating said feed water and said saturated steam of said steam circuit with exhaust gases of said fossil fuel circuit;
said at least one heat exchanger means including preheat stage means for preheating at least a portion of said feed water prior to introduction of said feed water to said reactor means;
and,
said at least one heat exchanger means including superheat stage means for superheating at least a portion of said saturated steam prior to introduction of said saturated steam to said turbine means.
