Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft einen Speisewasservorwärmer im Flammrohr eines Flammrohrkessels und besteht darin, daß miteinander verbundene kegelförmige Hohlkörper, welche zur Aufnahme des Speisewassers dienen, in einer zerlegbaren Reihe so hintereinander in das Flammrohr des Dampfkessels eingebaut sind, daß die größere Endfläche der Hohlkörper nach der Feuerstelle hin gerichtet ist,The invention relates to a feed water preheater in the flame tube of a flame tube boiler and consists in that conical hollow bodies connected to one another, which are used to receive the feed water, in a row that can be dismantled so one behind the other built into the flame tube of the steam boiler are that the larger end surface of the hollow body is directed towards the fireplace,

ίο so daß die heißen Feuergase, welche sonst das Bestreben haben, möglichst schnell in der Mitte des Flammrohres zu entweichen, besser ausgenutzt werden.ίο so that the hot fire gases, which otherwise endeavor to escape as quickly as possible in the middle of the flame tube, better be exploited.

Der Erfindungsgegenstand ist in Fig. ι im Längsschnitt und in Fig. 2 in der Vorderansicht eines Zweiflammrohrkessels dargestellt, während Fig. 3 einen Schnitt nach A-B der Fig. ι zeigt.The subject of the invention is shown in Fig. 1 in longitudinal section and in Fig. 2 in the front view of a two-flame tube boiler, while Fig. 3 shows a section according to AB of Fig.

Wie aus Fig. 1 zu ersehen ist, sind zur Aufnahme des vorzuwärmenden Speisewassers innerhalb des Flammrohres im Kessel kegelförmige Hohlkörper a in einer zerlegbaren Reihe so hintereinander angeordnet, daß die größere Endfläche der Hohlkörper nach der Feuerstelle hin gerichtet ist. Diese Hohlkörper α ruhen auf Böcken b, die auf zwei Schienen c und C1 fahrbar angeordnet sind (Fig. 3)· As can be seen from Fig. 1, conical hollow bodies a are arranged one behind the other in a dismountable row so that the larger end surface of the hollow body is directed towards the fireplace to receive the feed water to be preheated within the flame tube in the boiler. These hollow bodies α rest on brackets b, which are arranged to be movable on two rails c and C 1 (Fig. 3).

Das Kesselspeisewasser tritt durch das Rohr d ein und verteilt sich bei einem Zweiflammrohrkessel nach den Rohren e und βΛ. Vor dem Kessel sind ein Rückschlagventil f und darüber ein Absperrventil g angeordnet (Fig. 2). Diese Ventile sind auch hinter dem Kessel angebracht.The boiler feed water enters through pipe d and is distributed in a two-flame pipe boiler to pipes e and β Λ . A check valve f and above it a shut-off valve g are arranged in front of the boiler (FIG. 2). These valves are also located behind the boiler.

Die Wirkung ist folgende: Die Feuerungsgase prallen voll gegen die Stirnfläche des ersten Hohlkörpers a, gehen sodann gleichmäßig verteilt auseinander und bestreichen dabei die innere Wandung des Flammrohres, schließen sich darauf hinter dem Hohlkörper wieder mehr zusammen und treffen so den zweiten Hohlkörper auf seiner Stirnfläche usf. Es ist somit erreicht, daß die Gase, anstatt schnell durch die Mitte des Flammrohres zu entweichen, in möglichst gleichmäßiger Verteilung aufgehalten und wiederholt an die innere Wandung des Flammrohres geführt werden. Dabei wird einerseits das Speisewasser in den Hohlkörpern schnell erwärmt, andererseits wird die Ausnutzung der Gase zur Verdampfung befördert.The effect is as follows: The combustion gases collide fully against the end face of the first hollow body a, then spread evenly apart and brush the inner wall of the flame tube, then close again behind the hollow body and thus hit the second hollow body on its end face, etc. It is thus achieved that the gases, instead of escaping quickly through the center of the flame tube, are stopped in as uniform a distribution as possible and are repeatedly guided to the inner wall of the flame tube. On the one hand, the feed water is quickly heated in the hollow bodies, on the other hand, the use of the gases for evaporation is promoted.
