Abstract

The process for the combustion of fuels, particularly waste, in combustion installations with grate firing, wherein primary air is fed underneath the grate firing into the fuel bed and secondary air is fed above the fuel bed, is controlled in such a way that the intensity of combustion of the fuel on the firing grate is enhanced by increasing the oxygen content of the primary air and the intensity of combustion in the secondary combustion zone is restricted by reducing the oxygen content of the secondary air, and that an exhaust gas recycled from the combustion process is preferably used for reducing the oxygen content in the secondary air. <IMAGE>
