Abstract

Das Verfahren zur Regelung der Feuerleistung bei Verbrennungsanlagen, insbesondere Abfallverbrennungs­ anlagen, bei dem der im Rauchgas gemessene O2-feucht-­ Gehalt als übergeordnete Sollwert-Regelgröße für die Regelung der Brennstoffzufuhr und der gemessene Dampfmassenstrom als untergeordnete Sollwert-Regelgröße (10) für die Regelung der Primärluftzufuhr verwendet wird, sieht nach einer ersten Variante vor, daß der vorgegebene O2-feucht-Sollwert (7) in Abhängigkeit von der im Rauchgas gemessenen Feuerraumtemperatur (6) verändert wird. Diese veränderte Regelgröße (9) wird einem Regler (13) zugeführt, der Einfluß auf die Brennstoffbeschickung und/oder den Rostantrieb nimmt. The process for controlling the fire output in incineration plants, in particular waste incineration plants, in which the O 2 moisture content measured in the flue gas as the higher-level setpoint control variable for controlling the fuel supply and the measured steam mass flow as lower-level setpoint control variable (10) for the control the primary air supply is used, provides according to a first variant that the predetermined O 2 wet setpoint (7) is changed depending on the combustion chamber temperature (6) measured in the flue gas. This changed control variable (9) is fed to a controller (13) which influences the fuel feed and / or the grate drive.
