ABSTRACT:
The method for regulating the furnace output in incineration plants, particularly waste incineration plants, in which the O.sub.2 moist content measured in the flue gas is used as an overriding reference value regulating variable for regulating the combustible material feed and the measured steam mass flow is used as a subordinate reference value regulating variable (10) for regulating the primary air supply, provides, according to a first variant, that the preselected O.sub.2 moist reference value (7) is changed as a function of the furnace temperature (6) measured in the flue gas. This changed regulating variable (9) is fed to a regulator (13l ) which influences the combustible material feed and/or the grate drive.
