ABSTRACT:
A flameless combustion burner and method for operating the device. The burner includes an ignition zone with a starting device, a catalyst zone, and a plenum. To obtain flameless combustion, a fuel and a combustion supporting gas is introducted into the ignition zone from the plenum and a flame is initiated by means of the starting device. The products of combustion flow over the catalyst to heat it to a temperature where it can initiate flameless combustion. Then the flow of either the fuel or the combustion supporting gas or both is momentarily stopped and the flame is extinguished. The flow is then resumed while the catalyst is still hot and flameless combustion will start in the catalyst zone. The products of combustion are withdrawn from the catalyst zone and the heat is utilized in the burner.
