Abstract

Bei einem Turmkessel oder Einzug-Dampferzeuger (1) mit einem oberhalb der Wärmetauscherheizflächen angeordneten, zumindest abschnittsweise vorzugsweise als Querzug ausgebildeten Rauchgaskanal (4) mit anschließender Rauchgasleitung (5) und mit mindestens einer oberhalb des Feuerraums (2) im Rauchgaszug (3) angeordneten und sich bis in den Bereich des Rauchgaskanals (4) hineinerstreckenden, mindestens einen Regelzug mit mindestens einer zugeordneten Regelklappe (22,23) abgrenzenden Trennwand (9,19), soll eine Lösung geschaffen werden, die es ermöglicht, den Turmkessel oder Einzug-Dampferzeuger mit einem Regelzug auszustatten, der unter Beibehaltung einer zumindest im Wesentlichen unveränderten Kesselbauhöhe eine Temperaturregelung der Dampfaustrittstemperatur von Zwischenüberhitzerheizflächen ermöglichend ausbildbar ist. Dies wird dadurch erreicht, dass die mindestens eine Trennwand (9,19) den Rauchgaszug (3) in mindestens zwei getrennte Regelzüge (10,11) aufteilt, die jeweils zumindest abschnittsweise den Rauchgaskanal (4) ausbildende Bereiche aufweisen, wobei mindestens einem Regelzug (10,11) mindestens eine Regelklappe (22,23) zugeordnet ist.

In a tower boiler or intake steam generator (1) arranged above the Wärmetauscherheizflächen, at least partially preferably designed as a transverse flue flue gas duct (4) with subsequent flue gas line (5) and at least one above the combustion chamber (2) in the flue (3) arranged and A solution is to be created which extends into the region of the flue gas duct (4), at least one control draft with at least one associated control flap (22, 23) delimiting the tower boiler or intake steam generator to equip a rule train, while maintaining an at least substantially unchanged boiler construction height, a temperature control of the steam outlet temperature of reheater heating surfaces can be formed feasible. This is achieved in that the at least one partition wall (9, 19) divides the flue gas duct (3) into at least two separate control ducts (10, 11), each of which has sections forming the flue gas duct (4) at least in sections, whereby at least one control pass ( 10,11) is associated with at least one control flap (22,23).
