Abstract
A combined cycle cogeneration power plant includes a combustion turbine formed by an inlet for receiving fuel, an inlet for receiving air, a combustor for burning the combustion fuel and the air, and an outlet through which hot gaseous combustion product is released; a regenerative fuel heating system formed by a plurality of heat exchangers for transferring heat to combustion fuel for heating the combustion fuel, and modulating control valves for controlling temperature of the combustion fuel; a heat recovery steam generator (HRSG) connected to the outlet of the combustion turbine for receiving the gaseous combustion product. The HRSG is formed by a plurality of heat exchangers including steam/water drums, each having a surface blowdown connection, and evaporators connected to the steam/water drums, a water inlet connected with the heat exchangers of the HRSG, a steam outlet, and a stack for releasing the exhausted gaseous combustion product. A steam turbine is provided, and has a steam inlet for receiving steam from the steam outlet of the HRSG, and an exhaust steam outlet; a condenser is connected to the exhaust steam outlet of the steam turbine for condensing steam to a liquid condensate; at least one pump is provided for supplying the liquid condensate from the condenser to the HRSG; and at least one pump is provided for supplying feed water from at least one drum to the HRSG. A conventional-type power plant with a regenerative fuel heating system is also disclosed.
