Description

Schüttfeuerung für Dampfkessel o. dgl. mit im Brennstoffschachte eingebauten, nach unten offenen Auffangkanälen für Schwelgase, die dem Roste zugeführt werden. Die Erfindung betrifft eine Schüttfeuerung für Dampfkessel o. dgl., insbesondere für Niederdruckdampferzeuger, bei denen im Brennstoffschacht Auffangkanäle für Schwelgase, ,die dem Rost zugeführt werden, angeordnet sind.Bulk firing for steam boilers or the like with built-in in the fuel shaft, Downwardly open collecting channels for carbonization gases, which are fed to the grate. The invention relates to bulk firing for steam boilers or the like, in particular for low-pressure steam generators with collecting channels for carbonization gases in the fuel shaft, which are fed to the grate are arranged.

Von den bekannten Feuerungen dieser Art unterscheidet sich der Gegenstand .der Erfindung durch die besondere Anordnung des Brennstoffschachtes und der die Schwelgase auffangenden Kanäle, welche die Erhitzung des Brennstoffes vor seinem Zutritt zum Rost erhöht und dadurch eine verstärkte Entschwelung des Brennstoffes herbeiführt.The object differs from the known firings of this type .The invention by the special arrangement of the fuel shaft and the Smoldering gases collecting channels, which the heating of the fuel before his The access to the grate is increased and this means that the fuel is degreased more intensely brings about.

Die Erfindung besteht darin, daß .die Auffangkanäle im Schwelschacht oberhalb eines die Brennstoffzuführung zum Rost regelnden Sattels angebracht sind.The invention consists in that .the collecting channels in the smoldering shaft are attached above a saddle regulating the fuel supply to the grate.

Die Zeichnung stellt den Erfindungsgegenstand in einem Ausführungsbeispiel dar, und zwar zeigt Abb. i einen Längsschnitt, Abb. 2 einen Querschnitt nach Linie A-B in Abb. i.The drawing represents the subject matter of the invention in one embodiment Fig. 1 shows a longitudinal section, Fig. 2 shows a cross-section along the line A-B in Fig. I.

Über dem aus einem mittleren ebenen Teil a und zwei seitlichen treppenförmigen Teilen b bestehenden Roste ist ein Schacht c angeordnet, welcher einen Brennstoffvorrat aufnimmt. Im unteren Teil -d-es Schachtes c befindet sich der Sattel d.Above that from a central flat part a and two lateral step-shaped Parts b existing grates is a shaft c is arranged, which a fuel supply records. In the lower part -d-es shaft c is the saddle d.

Der zunächst oberhalb des Sattels d befindliche Teil des Brennstoffes wird entschwelt und die Schwelgase werden durch Rohre e aufgefangen, die unten Schlitze f für .den Eintritt .der Schwelgase besitzen. Die Rohre e sind nachdem, an der Vorderseite des Brennstoffschachtes c liegenden Raum g hin offen; an ihren Mündungen ist ein Rohr 1a entlanggeführt, welches an der unteren Seite Öffnungen besitzt und mit einem zur Zuführung von Luft :dienenden Rohr i verbunden ist. Die durch das Rohr i zugeleitete Luft strömt durch Öffnungen des Rohres h aus und bewirkt -die Verbrennung,der aus den Rohren e austretenden Schwelgase. Die bei der Verbrennung gebildeten Gase treten in den Raum k oberhalb des Rostes ein und vereinigen sich mit den dort entwickelten Verbrennungsgasen.The part of the fuel initially located above the saddle d is removed and the smoldering gases are caught by pipes e, the slits below f for .the entry of the carbonization gases. The tubes e are after, at the front of the fuel shaft c lying space g open; at their mouths is a Pipe 1a guided along, which has openings on the lower side and with a for the supply of air: serving pipe i is connected. The fed through the pipe i Air flows out through openings in the tube h and causes the combustion, the out the pipes e escaping carbonization gases. The gases formed during combustion occur into the space k above the grate and unite with those developed there Combustion gases.

Der obere Teil des Raumes g ist von dem Schacht c durch eine Wand in getrennt, die mit Öffnungen n versehen ist, welche gleichfalls Schwelgase in den Raum g eintreten lassen.The upper part of the room g is from the shaft c through a wall in separated, which is provided with openings n, which also smolder gases in let the room g enter.

Der zunächst über dem Sattel d liegende Teil des Brennstoffschachtes c ist nach oben verengt und besitzt in seiner Wandung Einbuchtuagen 1, die nach unten offene zu den Rohren e parallele Kanäle bilden, durch welche gleichfalls ein Teil der über dem Sattel d gebildeten Schwelgase aufgefangen und in den Verbrennungsraum g geführt wird.The part of the fuel shaft that is initially above the saddle d c is narrowed towards the top and has indentations 1 in its wall that follow At the bottom open to the tubes e form channels parallel through which also a Part of the carbonization gases formed above the saddle d are captured and fed into the combustion chamber g is performed.
