Description

Gliederheizkessel mit unterem Abbrand für Rohbraunkohlenfeuerung. Die Erfindung bezweckt, das Verbrennen von Rohbraunkohle in gußeisernen Gliederkesseln auf wirtschaftlichste Art zu ermöglichen, und besteht in der Vereinigung einer Reihe von Maßnahmen. Ein Gliederkessel nach der Erfindung ist in der Abbildung im senkrechten Schnitte gezeigt.Sectional boiler with lower combustion for raw lignite combustion. The invention aims to burn raw lignite in articulated cast iron boilers in the most economical way and consists in the unification of a number of measures. A sectional boiler according to the invention is in the figure in the vertical Sections shown.

Die Verteilung des Brennstoffes auf die notwendige Schichthöhe erfolgt durch einen im Winkel nach oben gerichteten Treppenrost, so daB die Brennstoffschicht von dem Luftstrom gut durchdrungen werden kann. Die Vorbereitung des Brennstoffes zur endgültigen Verbrennung geschieht durch Vertrocknung und die Absaugung der Wasserstoffgase durch nach oben gerichtete Durchbrechungen der Abschlußrippe der unteren Einschnürung des Füllschachtes. Unter Schaffung eines Grundfeuers, Ausnutzung der Verbrennungsgase durch möglichst lange Kesselzüge sowie Absaugung der Schwelgase im Endglied vom oberen Füllraum nach dem Aschenfall werden die Verbrennungsbedingungen für Braunkohle geschaffen.The fuel is distributed to the required layer height by a step grate pointing upwards at an angle, so that the fuel layer can be penetrated well by the air flow. Preparation of fuel final combustion takes place through drying out and the extraction of the hydrogen gases through upwardly directed openings in the end rib of the lower constriction of the hopper. By creating a basic fire, using the combustion gases through the longest possible boiler passes and suction of the carbonization gases in the end link from the The combustion conditions for lignite are determined by the upper filling space after the ash falls created.

Die Kohle wird in den Füllschacht des Kessels ca eingeworfen; sie wird hier durch die seitlich hochziehenden Rauchgase erwärmt und durch diese Erwärmung für die Verbrennung vorbereitet. Der entstehende Wasserdampf wird durch nach oben gerichtete Unterbrechungen h in, dem unteren eingezogenen Teil der Füllschachtrippe dem Verbrennungsraum g zugeführt. An der Spitze des angegossenem ,oder .eingelegten dachförmigen Rostes b wird die nach unten fallende Kohle in zwei Kohlenströme geteilt, wovon jeder nur eine ganz bestimmte, durch die Form des Kessels bedingte Höhe erreichen kann. Die seitlichen in der Fallrichtung des Brennstoffes stark nach unten geneigten Ansätze c des Treppenrostes lassen die Hauptluft zur Kohle hinzutreten, um hier die restlose Verbrennung der Kohle selbst durchzuführen. über das Ende d des Treppenrostes fallen die Rückstände nach dem Aschenraum e. Durch hochgezogene Zusatzluftkanäle f tritt die zusätzliche Verbrennungsluft aus dem Aschenfall e in den Verbrennungsraum g ein. Die Schwelgase werden durch Kanäle i im Endglied des Kessels nach dem Aschenraum c abgesaugt.The coal is thrown into the hopper of the boiler approx; she is heated here by the flue gases pulling up from the side and by this warming prepared for incineration. The resulting water vapor is through to the top directed Interruptions h in, the lower retracted part the filling chute rib is fed to the combustion chamber g. At the top of the molded one , or. inlaid roof-shaped grate b divides the falling coal into two Streams of coal divided, each of which is only a very specific one, due to the shape of the boiler conditional height can reach. The lateral ones in the direction of the fall of the fuel steeply downward sloping approaches c of the step grate allow the main air to Coal to come in to carry out the complete combustion of the coal yourself. The residues fall over the end d of the step grate to the ash chamber e. By raised additional air ducts f the additional combustion air emerges from the ash fall e into the combustion chamber g. The carbonization gases are released through channels i in the end link of the boiler to the ash chamber c.

Der Rost b kann als wassergekühlt an die Glieder angegossen oder als Einlegerost ausgebildet werden.The grate b can be cast onto the links as water-cooled or as Insert grate are formed.
