Anfahren eines Abhitzekessels mit wenigstens zwei getrennten Drucksystemen

摘要

The invention relates to a method for starting a waste-heat boiler (10), in particular in a gas turbine combined cycle power plant, having at least two separate pressure systems (12, 14) at different pressure levels. The steam generated is not used until after a prescribed pressure and temperature parameters have been reached for operating a steam turbine. Until the prescribed pressure and temperature parameters have been reached, the steam generated in the pressure system (12) at higher pressure is fed to the at least one pressure system (14) at lower pressure for the purpose of heating it. The invention also relates to an arrangement for carrying out this method.
