Description

Dampfkesselanlage mit Düsen- oder Rostfeuerung, wobei die Anlage aus zwei oder mehreren nebeneinanderliegenden.Verbundkesselsystemen besteht. Die Erfindung betrifft eine Dampfkesselanlage, die besonders für Kohlenstaubfeuerung oder aber auch für Rostfeuerung Anwendung finden kann. Die Anlage ist als Verbundanlage gedacht, in dem zwei oder mehrere Kesselsysteme nebeneinanderliegen und einen gemeinsamen Wasserumlauf besitzen. Das Kennzeichen zur Ermöglichung dieses gemeinsamen Wasserumlaufes ist dadurch gegeben, daB die untersten Rohrreihen der beiden Teilkammersysteme sich kreuzen und mit den Teilkammern des jeweils gegenüberliegenden anderen Kesselsystems verbunden sind.Steam boiler system with nozzle or grate firing, whereby the system is off consists of two or more adjacent composite boiler systems. The invention concerns a steam boiler system, which is particularly suitable for pulverized coal combustion or else can also be used for grate firing. The system is intended as a compound system, in which two or more boiler systems are side by side and one is shared Have water circulation. The mark to enable this common water circulation is given by the fact that the lowest rows of tubes of the two sub-chamber systems meet cross and with the sub-chambers of the other opposite boiler system are connected.

In der Zeichnung ist die Erfindung beispielsweise bei einem Dampfkessel mit Düsenfeuerung dargestellt, hierbei ist über dem Brennraum a in symmetrischer Anordnung ein Verbundwasserrohrkessel als Zweiheit gebaut. Jede Einheit davon besteht aus einem unteren und oberen Wasserrohrbündel b, b1 und Teilkammern c. Zwischen den beiden Rohrbündeln ist der Dampfüberhitzer d mit außenliegenden Sammelkästen e eingeschaltet. Über dem Überhitzer d befindet sich in paralleler Lage hierzu der Zwischenüberhitzer f. Die eine der oberen Teilkammern c" ragt über die Höhe des Wasserspiegels der Obertrommel g hinaus und nimmt die Überleitungsrohre h von der Obertrommel g auf. Oberhalb, und zwar in der Mitte der Gesamtanlage, befindet sich ein jeder Einheit gemeinsamer Dampfsammler i, von dien seitlich die Lufterhitzer k liegen.In the drawing, the invention is for example in the case of a steam boiler shown with nozzle firing, here is over the combustion chamber a in symmetrical Arrangement of a composite water tube boiler built as a binary. Every unit of it exists from a lower and upper bundle of water tubes b, b1 and sub-chambers c. Between The two tube bundles are the steam superheater d with external collecting tanks e switched on. The is located above the superheater d in a parallel position to this Reheater f. One of the upper sub-chambers c ″ protrudes above the height of the Water level of the upper drum g and takes the transfer pipes h from the Top drum g on. Above, in the middle of the entire system, is each unit has a common steam collector i, from which the air heater is located on the side k lie.

Die unterste Rohrreihe l stellt die Verbindung zwischen den beiden Kesseleinheiten her, indem die sich kreuzenden Rohre l mit der jeweils gegenüberliegenden Teilkammer c2 der anderen Kesseleinheit verbunden sind.The bottom row of tubes l provides the connection between the two Boiler units by placing the intersecting tubes l with the opposite one Partial chamber c2 of the other boiler unit are connected.
