EMI1.1
Die Erfindung bezieht sich auf eine Vorofenfeuerung, die einen Vorofen und einen Dampfkessel ausweist und bei der diese beiden Teile durch ein gemauertes Übergangsstück miteinander verbunden sind, das verfahrbar sein kann und das zum Überleiten der Feuergase aus der Vorfeuerung in den Dampfkessel dient.
Bei den bekannten Bauarten solcher Übergangsstücke besteht der Übelstand, dass das Mauerwerk des Übergangsstückes durch Abbrand einem sehr starken Verschleiss unterworfen ist und dass durch die starke Abstrahlung an dessen Aussenseite an diesem, den höchsten Feuerraumtemperaturen

ist durch eine Rohrleitung 11 mit dem Dampfraum des Kessels 7 und die Verteilerrohre 9 sind durch Rohrleitungen 12 mit dem Wasserraum des Kessels 7 verbunden. Zur Verstärkung der Dampfentwicklung sind noch Steigrohre 13 in die Rohre 8 eingeschweisst. Die Vorderwand 4 a des Übergangsstückes 4 ist gemauert und von abzuschirmenden Rohren freigehalten, um eine zu grosse Abkühlung der Feuergase und damit die Gefahr der Rauchbildung zu vermeiden.
Am Übergangsstück 4 sind Rollen 14 gelagert, mittels denen es auf unterzuschiebende Schienen 15 aufgesetzt und weggefahren werden kann, nachdem die an den Leitungen 11, 12 vorgesehenen Flanschverbindungen 16, 17 gelöst und das Übergangsstück von seinem Sitze 18 auf der Mauerung etwas abgehoben worden ist. Die Aussenseite der Rohrreihen 8 und des Dampfsammlers 10 sind gegen Abstrahlung durch eine Isolation 19 geschützt.

EMI1.1
The invention relates to a pre-furnace which has a pre-furnace and a steam boiler and in which these two parts are connected to one another by a bricked transition piece which can be moved and which serves to transfer the fire gases from the pre-furnace into the steam boiler.
In the known types of transition pieces of this type, there is the disadvantage that the masonry of the transition piece is subject to very strong wear due to burning and that the highest combustion chamber temperatures due to the strong radiation on its outside

is connected by a pipeline 11 to the steam space of the boiler 7 and the distribution pipes 9 are connected by pipelines 12 to the water space of the boiler 7. To increase the development of steam, riser pipes 13 are also welded into the pipes 8. The front wall 4 a of the transition piece 4 is bricked up and kept free of pipes to be shielded in order to avoid excessive cooling of the fire gases and thus the risk of smoke formation.
Rollers 14 are mounted on the transition piece 4, by means of which it can be placed on rails 15 to be pushed under and moved away after the flange connections 16, 17 provided on the lines 11, 12 have been loosened and the transition piece has been lifted slightly from its seat 18 on the masonry. The outside of the rows of tubes 8 and of the steam collector 10 are protected against radiation by insulation 19.
