Description

Dampfkesselanlage mit zwischen den der Feuerung zunächstliegenden Wasserrohrgruppen angeordnetem Überhitzer, einem dahinterliegenden Zwischenüberhitzer und hinter dein Kessel angeordnetem Luftvorwärmer.. Die Erfindung bezieht sich auf einer#anilifkesselanlage mit zwischen den der Feuerung zunächstliegenden Wasser:-ohn,ruppen angeordnetem tiberhitzer, einem dahinterliegenden Zwischenüberhitzer und hinter dem Kessel angeordnetem Luftvorwärmer.Steam boiler system with between those closest to the furnace Superheater arranged in groups of water pipes, an intermediate superheater behind and air preheater located behind the boiler .. The invention relates to a # anilifkesselanlage with between the water lying next to the furnace: -ohn, ruppen arranged superheater, an intermediate superheater behind and behind air preheater arranged in the boiler.

Das Neue der Erfindung besteht darin, daß durch Fortlassung eines Teiles der hinter den ersten Rohrgruppen mit überhitzer liegenden M'asserrohre ein durch eine Scheidewand von den Wasserrohren getrennter Raum zur Aufnahme eines Zwischenüberhitzers gebildet ist und der Durchgang der Gase durch zwei miteinander gekuppelte, gegenläufig sich bewegende Schieber bekanntt-@r Art derart geregelE wird, daß die Heizgase in besonderer Weise durch die einzelnen Rohrgruppen geleitet werden können.The novelty of the invention is that by omitting one Part of the M'asserpipes lying behind the first pipe groups with superheaters Space separated from the water pipes by a partition to accommodate a reheater is formed and the passage of the gases through two mutually coupled, opposite directions moving slide is known- @ this type is regulated in such a way that the heating gases in can be routed through the individual pipe groups in a special way.

Die Erfindung ist auf den Zeicbnun-en dargestellt, und zwar zeigen Abb. i und 2 Schnitte im rechten Winkel zueinander und Abb.3 und 4. die Anordnung der Schieber. Zwischen den oberen und unteren Rohrbänken des Kessels i ist der Ü berhitzer 2 bekannter Bauart angeordnet. An. einer Seite der Kesselrohre und isoliert von einem Teil dieser Rohre durch eine Wand 23 befindet sich ein Dampfzwisciienüberliitzer 3. Hinter dem Kessel i, dem L`berhitzer 2 und dein Niedererhitzer 3 befindet sich der Lufterhitzer q.. 5 und 6 zeigen bewegliche Schieber, die zur Steuerung der Kanäle 5a und 6,1 am oberen Teile der Kesselummantelung dienen. Die Schieber werden von Hubketten ; getragen, die auf Kettenrädern S laufen, die auf den Wellen g und ga sitzen und durch ein Getriebe io in entgegengesetzter Richtung umlaufen.The invention is shown on the drawing, namely show Fig. I and 2 sections at right angles to each other and Fig. 3 and 4 the arrangement the slide. Between the upper and lower tube banks of the boiler i is the Ü Superheater 2 of known type arranged. At. one side of the boiler tubes and insulated from a part of these tubes through a wall 23 there is an intermediate steam superlayer 3. Behind boiler i, the overheater 2 and your low heater 3 are located the air heater q .. 5 and 6 show movable slides that are used to control the ducts 5a and 6.1 are used on the upper part of the boiler casing. The sliders are from Lifting chains; that run on sprockets S that run on shafts g and ga sit and rotate through a gear io in the opposite direction.

Es ist zu ersehen, daß bei geöffnetem Schieber 6 der Schieber 5 geschlossen ist, so daß die ganzen Gase über einen Teil des Kessels i, den Überhitzer 2 nach dem Lufte rliitzer 4. strömen, während bei geschlossenem Schieber 5 und geöffnetem Schieber 5 die Gase über einen Teil des Kessels, des fiberhitzers in den Zwischenüberhitzer und von diesem nach dem Lufterhitzer gelangen.It can be seen that when the slide 6 is open, the slide 5 is closed is so that all the gases over part of the boiler i, the superheater 2 after the Lufte rliitzer 4. flow, while with the slide 5 closed and open Slide 5 the gases over part of the boiler, the superheater in the reheater and from there to the air heater.

In den Zwischenstellungen der Schieber können die Gase in regelbaren Mengen durch den Kessel r, Überhitzer 2 und Wiedererhitzer 3 und von diesem aus nach dem Lufterhitzer 4. gelangen. Die Pfeile beirrt Zwischenüberhitzer 3 (Abb. i) zeigen den Dampfweg an.The gases can be regulated in the intermediate positions of the slide Quantities through and from boiler r, superheater 2 and reheater 3 reach the air heater 4.. The arrows confuse reheater 3 (Fig. i) indicate the steam path.
