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.

Abstract: For the purpose of regulating the furnace output of incineration plants with a combustion grate, the primary air supply is variously regulated by zones along the length of the grate as well as in the transverse direction of the combustion grate. A monitoring device in the form of a video camera, which monitors the different burning behavior in the individual combustion zones, serves this purpose. In so doing, the recorded picture which is displayed on a monitor is resolved into individual picture lines and picture points by means of a freely programmable computer and the digital values obtained in this way, which represent a measurement for the combustion temperature, the flame radiation or the brightness on the respective combustion zone, are compared with preselected standard values. During a deviation, a corresponding regulation is carried out via a regulator, wherein regulating flaps in the air supply pipes, which guide the combustion air to the individual combustion zones, are adjusted for this purose.
