Abstract

A combined- cycle plant for the production of electric and thermal energy is provided with: a gas turbine unit (2); a steam turbine unit (3) comprising a low-pressure steam turbine (18); a boiler (4); and a district -heating unit (6), which is provided with a heat exchanger (46) for transferring heat to a district-heating fluid and with a flash tank vessel (48). The heat exchanger (46) is provided with a condensate collecting vessel (46) and the flash tank vessel (47) is designed to receive condensate from the condensate collecting vessel (46), generate steam and supply the generated steam to a first point upstream of the inlet of the low-pressure steam turbine (18).
