Abstract
A method and firing equipment for burning solid, liquid, or gaseous fuels, especially pulverized coal. The method includes the steps of tangentially introducing main fuel via main burners into a combustion chamber, where the fuel is burned, introducing reducing fuel via reduction burners into the combustion chamber to reduce the nitrogen oxides produced during the combustion of the main fuel, with the reducing fuel being burned under partial stoichiometric conditions, and, to ensure the burning-out of the fuel introduced into the combustion chamber, introducing burn-air above the feed of the main fuel and the reducing fuel, with a helically rising flow being provided in the combustion chamber. The reducing fuel of a given reduction burner is mixed, at a given distance from the opening of the associated main burner, with the curved afflux leaving that main burner for helical flow about the center of the combustion chamber.
