International Classification:
F01K 23/06
US Classification:
60 39182, 60653
Abstract:
A combined cycle (CC) power plant comprises a gas turbine; a steam turbine; a condenser; a heat recovery steam generator (HRSG), the HRSG comprising an attemperator and a high pressure superheater and attemperator, the high pressure superheater and attemperator disposed at a discharge terminal of the high pressure superheater and attemperator and at a discharge terminal of the HRSG reheater; a generator, and a fuel supply. The steam turbine is connected by multiple conduits to the heat recovery steam generator (HRSG) and the steam turbine exhaust is connected to the condenser wherein support multiple ancillary and reserves to load follow, execute regulation, and meet intermediate power generation service needs in an expedited start process.

International Classification:
F02C 6/18, F02C 7/26
US Classification:
60778, 60 39182, 60786
Abstract:
Methods and apparatus for fast starting and loading a combined cycle power system are described. In one example embodiment, the method includes loading the gas turbine at up to it's maximum rate, and loading the steam turbine at its maximum rate with excess steam bypassed to the condenser while maintaining the temperature of steam supplied to the steam turbine at a substantially constant temperature from initial steam admission into the steam turbine until all steam generated by the heat recovery steam generator is being admitted to the steam turbine while the gas turbine operates at up to maximum load.
