In a combustion plant, which is operated with fossil fuels, the waste gases (A) from the combustion chamber (22) are cooled in a heat exchanger (X). A portion of these cooled waste gases (A') is mixed with fresh air (L) and conducted via a blower (D) in the direction of the burner (Z). This waste gas/fresh air mixture forms the combustion air (15) for the burner (Z). Before this combustion air (15) is introduced into the burner (Z), it is heated again in the heat exchanger (X'). The combustion air (15) thus preheated guarantees complete evaporation of a liquid fuel (12) and counteracts the high flame temperature peaks in the combustion chamber (22), directly after the burner (Z), which are responsible for the formation of nitrogen oxide. The burner (Z) can be operated with liquid and/or gaseous fuel. …<IMAGE>… |
