摘要: The invention relates to a continuous steam generator (1) comprising a combustion chamber (2) having a number of burners for fossil fuel and an outside wall (12) composed of steam generator pipes (20) that are welded to each other gas-tight, wherein a vertical gas flue (8) is connected downstream of the combustion chamber (2) on the hot gas side in an upper area (4) through a horizontal gas flue (6), wherein a part of the outside wall (12) facing the vertical gas flue (6) and below the horizontal gas flue (6) is inclined inward and thus forms a nose (14) projecting into the combustion chamber (2) with the bottom (16) of the adjacent horizontal gas flue (6), wherein the continuous steam generator should have a simplified design and a particularly high reliability in operation. For this purpose, a number of support pipes (26) are connected downstream of at least one part of the steam generator pipes (20) of the nose (14) at the upper end thereof on the flow medium side, wherein said support pipes are guided substantially vertically to the lower end of the nose (14).

摘要: The invention relates to a continuous evaporator (1) for a horizontally constructed waste heat steam generator (2), which comprises a first evaporator heating surface (8) having a plurality of essentially vertically arranged first steam generator tubes (13) through which a flow medium can flow from bottom to top, and a second evaporator heating surface (10) which is mounted downstream of the first evaporator heating surface (8) on the flow medium side. Said second evaporator heating surface comprises a plurality of additional essentially vertically arranged second steam generator tubes (14) through which a flow medium can flow from bottom to top. The aim of the invention is to produce a continuous evaporator which is simple to construct and which has a long service life. As a result, the second steam generator tubes (14) are designed in such a manner that the average mass flow density which can be controlled in the full load operation does not fall below a predetermined minimum mass flow density in the second steam generator tubes (14).

摘要: Ein Durchlaufdampferzeuger (1) mit einer Brennkammer (2) mit einer Anzahl von Brennern für fossilen Brennstoff und einer aus gasdicht miteinander verschweißten Dampferzeugerrohren (20) gebildeten Umfassungswand (12), wobei der Brennkammer (2) heizgasseitig in einem oberen Bereich (4) über einen Horizontalgaszug (6) ein Vertikalgaszug (8) nachgeschaltet ist, wobei ein dem Vertikalgaszug (6) zugewandter Teil der Umfassungswand (12) unterhalb des Horizontalgaszuges (6) einwärts geneigt ist und dadurch mit dem Boden (16) des angrenzenden Horizontalgaszuges (6) eine in die Brennkammer (2) hineinstehende Nase (14) bildet, soll bei einer besonders hohen Zuverlässigkeit im Betrieb eine vereinfachte Konstruktion aufweisen. Dazu ist zumindest einem Teil der Dampferzeugerrohre (20) der Nase (14) an deren oberen Ende eine Anzahl von Tragrohren (26) strömungsmediumsseitig nachgeschaltet, die im wesentlichen vertikal zum unteren Ende der Nase (14) geführt sind.
