Abstract

Method for burning fuel, wherein in order to obtain temperature T necessary for initializing the F2 operating mode, first the combustion chamber is preheated with burning products from the F1 operating mode to temperature Tk and the air supplying the burner is preheated in the heat exchanger to temperature TAIR, which can range from the ambient temperature to 450°C, and maximally to 600°C. This relationship is defined by T = 1/2(Tk + TAIR), after meeting this condition the secondary fuel is supplied at the F2 operating mode. At the F2 operating mode, the fuel is supplied through one lance with a nozzle, from which a stream flows parallel to the stream of burning mixture of the air and fuel from the first burning segment and exhaust gases, mixes and burns together causing the extension of the flame, extension of the burning time, even distribution of temperatures in the combustion chamber and low emission of toxic compounds.
