Title:
COMBINED CYCLE POWER PLANT
Document Type and Number:
WIPO Patent Application WO/2012/116980
Kind Code:
A3
Abstract:
A combined cycle power plant (1) with a gas and steam turbine system (GT, ST) arranged on a single shaft (2) and integrated with a cogeneration plant (100) having a heat consumer such as a district heating system or industrial plant, comprises one or more steam extractions at an intermediate-pressure steam turbine (7) that are arranged at the upper casing half-shell (7) of the turbine and extraction steam lines (11, 12) that lead the extracted steam to heat exchangers (31, 32) of the cogeneration plant (100). The steam extraction outlets are arranged either singly at or near the uppermost point of the casing or in pairs to either side of the uppermost point of the casing. The specific arrangement of the extractions allows a floor-mounting of the single-shaft combined cycle power plant (1) and as such a cost and space efficient realization of the power plant.
