Abstract
A power plant includes a prime mover for burning fuel and producing work and hot exhaust gases, and heat exchanger apparatus that is responsive to the hot exhaust gases and to pre-heated steam condensate for converting the latter into high-pressure steam and for producing heat depleted exhaust gases. A combustor, preferably, a fluidized bed combustor, is responsive to burning fuel for supplying additional heat to a product of the heat exchanger apparatus, and producing combustion products. The combustion products are supplied to a superheater for producing superheated, high pressure steam from the high pressure steam supplied from the heat exchange apparatus. A high pressure steam turbine expands the superheated, high pressure steam and produces power and exhaust steam that is condensed to steam condensate in a condenser. Finally, the power plant includes an economizer that is responsive to the heat-depleted combustion products and to the steam condensate for producing the pre-heated condensate used by the heat exchange apparatus.
