A device is for preheating combustibles in combined gas and steam turbine installations. The device includes at least one steam generator for heating, evaporating and superheating feed water, which has a feed water preheater, an evaporator and a superheater. At least part of the heated feed water is used for preheating combustibles in a combustible preheater, which can be supplied with feed water of a predetermined temperature by a feed water supply line. Once the combustible has been heated, the cooled feed water can be drained using a feed water drain line. The device is configured so that it can be used in different gas turbine installations and its heating capacity can be rapidly and cost-effectively adapted to predetermined combustible preheating requirements. To achieve this, the combustible is preheated in stages, which can be activated individually as required and through which the combustible can successively pass.

The invention relates to a method for operating a steam power station and a power plant as well as a corresponding steam power station. According to the invention, essentially all of the water that is drained from at least one pressure stage of the steam power station is collected, stored, and recirculated into the water circuit of steam power station.

The invention relates to a method and a device for treating contaminated water in a steam power installation, and to a corresponding steam power installation. According to the invention, steam and water are separated between a first steam-collecting drum of a pressure level and a second steam-collecting drum of a lower pressure level.

A method is provided for connecting at least one further steam generator to a first steam generator in a power plant. The power plant includes at least two steam generators and a steam turbine, in which a fluid used to drive the steam turbine is conveyed in a fluid circuit having a plurality of steam systems. The steam systems are assigned individual steam generators and are able to be separated from one another by shut-off valves. The fluid of at least the first steam generator is connected to the steam turbine. The method involves opening the shut-off valve of at least one first steam system of the at least one further steam generator before the steam of the at least one further steam generator has reached approximately the same steam parameters as the steam of the first steam generator, so that steam can flow into the further steam generator.
