摘要： A method for operating a combined-cycle power plant includes utilizing heat contained in an expanded working medium of an associated gas turbine operable with both gas and oil as fuel, to generate steam for an associated steam turbine having at least one high-pressure stage. After a change of the operation of the gas turbine from gas to oil, feed water to be supplied to the high-pressure stage is divided into a first and a second partial stream, and only one of the partial streams is preheated. Particularly high plant efficiency may be achieved with the method, irrespective of the fuel being used for the gas turbine, at a low outlay in terms of apparatus and operational requirements. A combined-cycle power plant that is particularly suitable for carrying out the method includes a bypass line connected in parallel with a feed-water preheater associated with the high-pressure stage.

摘要： A steam generator, in particular a waste-heat steam generator, includes first and second evaporator heating surfaces located in an elongate gas flue for hot gas. A first supply line for feed water is throughflow-connected on an inlet side to the first evaporator heating surface, while the second evaporator heating surface is throughflow-connected on an inlet and an outlet side to a low-pressure drum. The low-pressure drum is provided with a second supply line for feed water. The first supply line has a first treatment point and the second supply line a second treatment point. Each of the treatment points serves for adding and/or extracting chemicals for water treatment, so that each evaporator heating surface can receive only feed water which is conditioned according to regulations applying to that evaporator heating surface. A method for operating the steam generator is also provided.
