摘要： The present invention concerns an integration construction between a steam boiler provided with a combustion chamber and a steam turbine. The steam is conducted from the steam boiler (10) along a connector to the steam turbine (11) for rotating an electric generator (K) producing electricity. The supply water circulated via the steam boiler (10) is vaporized in a vaporizer (190) located in the steam boiler (10) and superheated in a superheater (120). The supply water is conducted into the boiler through an economizer (20) acting as a heat exchanger, where heat is transferred from the flue gases of the boiler into the supply water. The economizer (20) is provided with at least two sections, comprising at least one first economizer section (20a1) and at least one second economizer section (20a2). The supply water is conducted from the first economizer section (20a1) to a supply water preheater formed from a heat exchanger (14), where thermal energy is transferred from bled steams of the steam turbine either directly or via a medium, advantageously water, into the supply water. The supply water preheated with bled steams of the steam turbine is conducted in the steam boiler (10) to the second economizer section (20a2) and further to the vaporizer (190) and the superheater (120) and therethrough, in the form of steam, to the steam turbine. In the integration construction, the temperature of the supply water is raised continuously as the supply water is flowing in the first economizer section (20a1) and from the first economizer section (20a1) to the supply water preheater (14) and threthrough, to the second economizer section (20a2). The connector (13a1.1) leading to the supply water preheater (14) comprises a valve (21) for controlling the bled-steam.

摘要： In a combined cycle power plant operable on either gas or liquid fuels maximum design efficiency is achieved at the lowest HRSG stack temperatures. This can be optimized for operation on natural gas but for liquid fuel operation consideration must be given to sulfur cold end corrosion. A feedwater recirculation loop is shown which allows for selectively heating feedwater during liquid fuel operation and for non-heating during gas operation. Economizer recirculation is also introduced to prevent economizer steaming.
