Abstract

Bei einer Kesselanlage für eine Wärmeerzeugung, welche im wesentlichen aus einem Brennraum (17) und aus einem kopfseitig des Brennraumes wirkenden Vormischbrenner besteht, wird abströmungseitig dieses Vormischbrenners eine Begrenzungsvorrichtung (103, 104, 105) angeordnet. Diese hat die Aufgabe, die Ausbreitung einer vom Vormischbrenner gebildeten Rückströmzone (24) zu verhindern, dergestalt, dass eine zu starke Abkühlung der reagierten Rückströmgase innerhalb des Brennraumes verhindert wird.
