ABSTRACT:
A steam raising apparatus for a gas turbine driven powerplant in which fuel and water are introduced into a heat exchanger at multiple pressures and steam/fuel mixtures are removed from the heat exchanger at multiple pressures, some of which are above the desired pressure for combustion and some of which are below. The higher pressure flows are reduced in pressure by using them to drive a steam turbine coupled to a steam compressor, and the lower pressure flows are increased in pressure by means of the compressor. The resultant flows are then be combined into a single flow at the required pressure and routed to the combustor. Alternatively, multiple steam jet ejectors forming a thermocompressor assembly are used instead of the steam turbine/steam compressor assembly.
