The invention relates to a heat shield arrangement for a hot gas (m)-guiding component, which comprises a number of heat shield elements arranged side-by-side on a supporting structure while leaving a gap there between. A heat shield element can be mounted on the supporting structure whereby forming an interior space which is delimited in areas by a hot gas wall to be cooled, with an inlet channel for admitting a coolant into the interior space. According to the invention, a coolant discharge channel is provided for the controlled discharge of coolant from the interior space and, from the interior space, leads into the gap. Coolant can be saved and efficiently used by the specific coolant discharge via the coolant discharge channel, and reduction in pollutant emissions can also be achieved. The heat shield arrangement is particularly suited for linking a combustion chamber of a gas turbine.

The invention relates a method for improving the hot-starting behavior of a turbomachine. By virtue of the setting of a radial gap formed between a brushing edge of a blade profile and a guide face lying opposite this, in which setting a guide ring forming the guide face can be acted upon with a coolant, the hot-starting behavior can be improved, in that the guide ring is cooled before the start of the machine.

A method for generating heat by flameless combustion of a fuel in a gas flow having an oxygen content, includes passing a gas flow through at least one heating device, along at least one delivery device for fuel, and along at least one catalytically active element. A predominant part of the gas flow is passed through a loop while passing through a feed apparatus and along the at least one catalytically active element. A gas having an oxygen content is fed into the loop, and some of the gas flow is discharged from the loop. Fuel is admixed with the gas flow only to such an extent that a resultant fuel-gas mixture is not itself ignitable. An apparatus for introducing heat into a component, includes a gas carrying system for conducting a gas flow carrying heat produced by flameless combustion of a fuel. The gas carrying system has at least one loop, a delivery device for delivering fuel, a gas inlet, and a gas outlet. Disposed in the loop are a component for heat absorption from the gas flow flowing around and/or through the component, a feed device for maintaining the gas flow in the loop, a heating device, and a catalytically active element.
