Description

Feuerung für Heizrohrkessel mit Teile der Kesselstirnwand überdeckenden Umkehrkammern zur Umführung der Heizgase. Den Gegenstand der Erfindung bildet eine Vorrichtung an Heizrohrkesseln zum Umkehren der Rauchgase und Vermischen derselben mit zugeführter Frischluft zwecks vollkommenerer Verbrennung und besserer Ausnutzung der Gase.Firing for heating tube boilers with parts of the boiler front wall covering Reversing chambers for bypassing the hot gases. The subject of the invention is a Device on heating tube boilers for reversing the flue gases and mixing them with fresh air supplied for more complete combustion and better utilization of the gases.

Das Neue der Erfindung besteht darin, daß an den Stirnwänden des Kessels in der Feuerkiste und in der Rauchkammer gegeneinander versetzte Kammern angeordnet sind in welche jeweils etwa zwei. Drittel der Kes.selheizrohre einmünden, wodurch eine Umkehrung der die. Heizrohre durchziehenden Rauchgase und Mischung mit Frischluft stattfindet, so daß die nach der Beschickung unvollkommen verbrannten Gase und Brennstoffteilchen durch die sich im Brennraum erhitzendeFordere Umkehrkammer und durch vom Rost her durch Bodenöffnungen eintretende Flammen entzündet und verbrannt; werden. Die für die Verbrennung der Rauchgas in der vorderen Umkehrkammer erforderliche Frischluft wjxd durch von außen in dieselbe eingeführte Rohrstutzen eingesaugt. Beide Umkehrkaihmern sind zwecks Reinigung der innerhalb dieser Kammern liegenden Kesselheizrohre mit aufklappbaren Vorderwänden versehen.The novelty of the invention is that on the end walls of the boiler Staggered chambers are arranged in the fire box and in the smoke chamber are each about two. Third of the Kes.selheizrohre open out, whereby a reversal of the. Flue gases passing through the heating pipes and mixing with fresh air takes place so that the gases and fuel particles incompletely burned after charging through the forward reversing chamber, which heats up in the combustion chamber, and through the grate ignited and burned flames entering through openings in the floor; will. The for the combustion of the flue gas in the front reversing chamber required fresh air wjxd sucked in through pipe sockets introduced into the same from the outside. Both reverse embarkers are included for the purpose of cleaning the boiler heating pipes located within these chambers hinged front walls.

Auf der Zeichnung ist der Erfindungsgegenstand in einer beispielsweisen Ausführungsform dargestellt: es zeigt: Abb. i einen Längsschnitt durch einen Lokomotivkessel, Abb. a einen Querschnitt nach A-B der Abb. i -und Abb.3 einen Querschnitt nach C-D der Abb. i.The subject of the invention is shown in an exemplary manner in the drawing Embodiment shown: it shows: Fig. I a longitudinal section through a locomotive boiler, Fig. A is a cross section according to A-B of Fig. I - and Fig. 3 is a cross section according to C-D of fig. i.

In der Feuerkiste a und in der Rauchkammer b sind an den Stirnseiten des Kessels etwa -zwei Drittel der Rauchrohre von unten bzw. oben an einschließende Umkehrkammern c und d vorgebaut, deren Vorderwände e, f aufklappbar bzw. jalousieartig ausgebildet sind. Diese Umkehrkammern sind gegeneinander in der Höhe versetzt, so daß die Kammer in der Feuerkiste zwei Drittel des Kesselheizrohrbündels von Unterkante Kessel gerechnet und die Kammer ;in der Rauchkammer zwei Drittel des Heizrohrbündels von Oberkante Kessel gerechnet einnimmt. In die Rauchkammer c in der Feuerkiste sind Rohrstutzen g, g1 von außen eingeführt, durch welche während des Betriebes Frischluft eingesaugt wird. Der Zustrom kann reguliert werden.. Der einen Feuerschirm bildende Boden der Umkehrkammer c besitzt eine oder mehrere D.urchbrechungen h, durch welche Flammen vom Verbrennungsraum in die Umkehrkammer hineinzüngeln. Die klappbaren Vorderwände der Umkehrkammern c und d werden durch Handhebel i oder durch ein gemeinsames Gestänge bewegt. Die Rauchgase ziehen. von Tier Feuerkiste in den freiliegenden oberen. Teil der Heizrohre, .kehren ihre Richtung in der Umkehrkammer d um und strömen durch die eingeschlossenen Heizrohre in die Umkehrkammer c der Feuerkiste. Hier vermischen sie sich mit Frischluft, und die noch unverbrannten Gase werden einmal durch das -erhitzte Mauerwerk des Feuerschirms und weiterhin durch die in die Umkehrkammer eintretenden Flammen, welche durch die Durchbrechungen h im # Feuerschirm hindurchschlagen, entzündet. Die nun völlig verbrannten. Gase strömen dann durch das untere Drittel der Heizrohre zur Rauchkammer b und durch den Auspuff ins Freie.In the fire box a and in the smoke chamber b, about two-thirds of the smoke tubes from below and above are built in front of enclosing reversing chambers c and d, the front walls e, f of which can be opened or are louvred-like. These reversing chambers are offset from one another in height so that the chamber in the fire box takes up two thirds of the boiler heating tube bundle from the lower edge of the boiler and the chamber in the smoke chamber takes up two thirds of the heating tube bundle from the upper edge of the boiler. In the smoke chamber c in the fire box pipe sockets g, g1 are introduced from the outside, through which fresh air is sucked in during operation. The inflow can be regulated. The bottom of the reversing chamber c, which forms a fire screen, has one or more openings h through which flames from the combustion chamber lick into the reversing chamber. The foldable front walls of the reversing chambers c and d are moved by hand levers i or by a common linkage. Draw the fumes. of animal fire box in the exposed top. Part of the heating tubes. Reverse their direction in the reversing chamber d and flow through the enclosed heating tubes into the reversing chamber c of the fire box. Here they mix with fresh air, and the still unburned gases are ignited once by the heated masonry of the fire screen and then by the flames entering the reversal chamber, which break through the openings h in the fire screen. The now completely burned. Gases then flow through the lower third of the heating pipes to the smoke chamber b and through the exhaust into the open air.

Bei einer Reinigung der Herzrohre werden die Umkehrkammern, c und d vom Kessel abgenommen oder deren Vorderwand wird hochgeklappt.When cleaning the heart tubes, the reversal chambers, c and d removed from the boiler or its front wall is folded up.

Auf diese Weise ist es möglich, den Brennstoffverbrauch, insbesondere bei gasreicher englischer Kohle, herabzusetzen.In this way it is possible to reduce fuel consumption, in particular in the case of gas-rich English coal.
