Abstract

Die Erfindung betrifft ein Verfahren zur Verbrennung min­ derwertiger Brennstoffe, insbesondere auf Braunkohlenbasis. Das Verfahren wird ohne Veränderung an den jeweils vorhan­ denen, vorher verwendeten Hochdruckdampferzeugern einge­ setzt. The invention relates to a method for combustion min of such fuels, in particular based on lignite. The procedure is carried out without changing the existing those previously used high pressure steam generators puts.

Es besteht die Aufgabe, minderwertige Brennstoffe in herkömmlichen Hochdruckdampferzeugern unter Verwen­ dung entsprechender Vorfeuerungen nach dem Prinzip der Schwelgasnachverbrennung zu verbrennen, wobei die Schwelgasverbrennung weitestgehend im Dampferzeuger stattfindet. The task is to inferior fuels conventional high pressure steam generators under use appropriate pre-firing according to the principle of Burn carbonization afterburning, the Smoldering gas combustion largely in the steam generator takes place.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Brennstoffe bei geregelter Zuführung von primärer Ver­ brennungsluft verschwelen. Dazu wird zunächst in der Vor­ feuerung eine reduzierend wirkende Atmosphäre erzeugt. Da­ nach erfolgt die Beschleunigung der einzelnen Schwelgas­ ströme in Flammenrohren und ihre Verwirbelung mit Sekundär­ luft beim Eintritt in den Hochdruckdampferzeuger. The object is achieved in that the fuels with regulated supply of primary Ver burn the combustion air. This will be done first in the pre combustion creates a reducing atmosphere. There after the acceleration of the individual carbonization gas takes place flows in flame tubes and their swirling with secondary air when entering the high pressure steam generator.
