Abstract: A method for making a flow conducting unit cool down more slowly where the flow conducting unit has a holding unit and is penetrated by a heat transfer medium, the temperature of the heat transfer medium is reduced such that a wall of the flow conducting unit cools down, and the holding unit dissipates thermal energy such that the wall cools down more slowly.

Abstract: A method for operating a combined cycle power plant, wherein the combined cycle power plant has a gas turbine and a steam turbine and also a shutting-down device, and wherein, for shutting down the gas turbine and the steam turbine, the gas turbine and the steam turbine are operated within a time window that extends from the beginning of the shutting-down procedure at a first time to the falling of the steam temperature to a lower limit value at a second time by the shutting device in such a way that the gas turbine and the steam turbine are relieved substantially at the same time and the block power falls to zero, thermal energy that is stored in the combined cycle power plant preventing immediate falling of a steam temperature to operation below a minimum power output of the gas turbine within the time window.

Abstract: A method for operating a combined cycle power plant includes additional burners being arranged in the waste heat boiler, the burners being supplied with secondary air from the gas turbine, the gas turbine is operated without a supply of fuel, and driving is effected by means of a start-up inverter. A plant includes a waste heat boiler, additional burners for generating thermal energy being arranged within the waste heat boiler, a gas turbine designed such that the necessary air mass flow for the additional burners can be supplied by the gas turbine, wherein the gas turbine is operated without a supply of fuel, the plant further including a start-up inverter, wherein driving is effected by means of the start-up inverter.
