Abstract

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.
