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.
