Abstract

Zur Einhaltung einer konstanten Regelgröße insbesondere der Bettemperatur einer Wirbelschichtfeuerung dient ein Regelorgan (24), das in einer Zuführungsleitung (20) für die Zuführung von Fluidisierungsluft zu einem Siphon (15) angeordnet ist, über den aus dem Rauchgas der Wirbelschichtfeuerung abgeschiedener Feststoff in das Wirbelbett (5) zurückgeführt wird. Der Stellantrieb (23) des Regelorgans (24) ist mit einem in dem Wirbelbett (5) angeordneten Temperaturfühler (27) in der Weise gekoppelt, daß die Menge der Fluidisierungsluft erhöht wird, wenn die gemessene Bettemperatur einen vorgegebenen Wert überschreitet. Die Menge der Fluidisierungsluft wird verringert, wenn die gemessene Bettemperatur den vorgegebenen Wert unterschreitet.
