Abstract

Es wird ein Dampfblaskasten (50) zum Aufbringen von Dampf auf eine über eine Walze (30) einer Papiermaschine geführte Papierbahn angegeben, mit einer sich quer zur Bahnlaufrichtung (53) entlang der Walze (30) erstreckenden, abgeschlossenen Dampfblaskammer (60), der Dampf zuführbar ist und deren der Walze zugewandte Vorderwand (62) eine Mehrzahl von Dampfaustrittsöffnungen (74) aufweist. Zwischen der Vorderwand (62) des Dampfblaskastens (50) und der Walze (30) ist ein Dampfausbreitungsraum (76) gebildet. Zur Temperaturregelung bzw. zur Regelung der im Dampfausbreitungsraum (76) auf die Papierbahn übertragenen Wärmemenge ist ein sich quer zur Bahnlaufrichtung erstreckender Austrittskanal (96) zur Zumischung von Luft vorgesehen. Auf diese Weise läßt sich eine feinfühlige, zonenweise getrennte Steuerung der Erwärmung der Papierbahn erreichen. Der Dampfausbreitungsraum (76) ist durch Zuführung von Luft auf der Einlaufseite (92) zonenweise kühlbar.

Figure 00000001
A steam blower box (50) for applying steam to a paper web guided over a roller (30) of a paper machine is specified, with a closed steam blowing chamber (60), which extends transversely to the web running direction (53) along the roller (30), the steam can be fed and the front wall (62) facing the roller has a plurality of steam outlet openings (74). A steam expansion space (76) is formed between the front wall (62) of the steam blow box (50) and the roller (30). To regulate the temperature or to regulate the amount of heat transferred to the paper web in the steam spreading space (76), an outlet duct (96) extending transversely to the web running direction is provided for admixing air. In this way, sensitive, zone-by-zone control of the heating of the paper web can be achieved. The steam spreading space (76) can be cooled zone by zone by supplying air on the inlet side (92).
