Abstract

Zur Regelung der Feuerleistung von Verbrennungsanlagen mit einem Verbrennungsrost (1) wird die Primärluftzufuhr sowohl über die Rostlänge als auch in Querrichtung des Verbrennungs­ rostes zonenweise unterschiedlich geregelt. Hierzu dient eine Überwachungseinrichtung in Form einer Videokamera (17), die das unterschiedliche Abbrandverhalten in den einzelnen Verbren­ nungszonen überwacht. Dabei wird das aufgenommene und auf einem Monitor (21) aufgezeigte Bild mittels eines frei program­ mierbaren Rechners (22) in einzelne Bildzeilen und Bildpunkte aufgelöst und die so erhaltenen Digitalwerte, die ein Maß für die Brenntemperatur, die Flammenstrahlung oder die Helligkeit auf der jeweiligen Verbrennungszone darstellen, mit vorgegebenen Richtwerten verglichen. Bei Abweichung wird über einen Regler (23) eine entsprechende Regelung durchgeführt, wobei zu diesem Zwecke Regelklappen (17) in Luftzuführungsrohren (16) verstellt werden, welche die Verbrennungsluft zu den einzelnen Verbrennungs­ zonen leiten. To control the fire performance of incinerators with A combustion grate (1) is the primary air supply both over the grate length as well as in the transverse direction of the combustion rust is regulated differently in zones. This is served by a Monitoring device in the form of a video camera (17), the the different burning behavior in the individual burns monitored. The recorded and on a monitor (21) displayed image using a free program mable computer (22) into individual image lines and pixels resolved and the digital values thus obtained, which is a measure for the firing temperature, the flame radiation or the brightness display on the respective combustion zone, with given Benchmarks compared. If there is a deviation, a controller is used (23) a corresponding regulation is carried out, with regard to this Purpose control flaps (17) in air supply pipes (16) adjusted the combustion air to the individual combustion lead zones.
