Description

Vorfeuerung für Flammrohrkessel aus Treppen- und Planrost. Die Erfindung betrifft eine Vorfeuerung für Flammrohrkessel mit Treppenrost und Planrost. Sie kennzeichnet sich darin, daß der an den die Flammrohre beheizenden Treppenrost anschließende Planrost unterhalb des Kessels eingebaut ist und einen Unterzug beheizt, der nach einer rückwärtigen, auch von den Flammrohren gespeisten Rauchkammer führt, die anderseits an die Seitenzüge angeschlossen ist.Pre-firing for flame tube boilers made of step and plan grate. The invention relates to a pre-firing system for flame tube boilers with a step grate and plan grate. she is characterized by the fact that the step grate adjoining the grate that heats the flame tubes Plan grate is installed below the boiler and a beam is heated, which after a rear smoke chamber, also fed by the flame tubes, leads to the other is attached to the sidecuts.

Die Zeichnung veranschaulicht eine beispielsweise Ausführung der Erfindung, und zwar ist Abb. i eine Draufsicht, teilweise aufgerissen, Abb. 2 ein Mittellängsschnitt und Abb.3 ein Längsschnitt durch die Seitenkanäle.The drawing illustrates an example embodiment of the invention, namely Fig. 1 is a plan view, partially broken away, Fig. 2 is a central longitudinal section and Fig.3 shows a longitudinal section through the side channels.

Die Seitenwände a, Stirnwände b und w und Bett d bilden das Mauerwerk. e ist der mit zwei Flammrohren f sowie Mannloch u und Auslauf v vorgesehene Kessel. Im Mauerwerk sind zwei an der Unterhälfte des Kessels hinlaufende Kanäle n gebildet und zwei an der Oberhälfte hinlaufende Kanäle o. Vorn ist eine Rauchkammer p gebildet und hinten ein Raum mit Rückwand w, der durch eine Zwischendecke in Oberraum r und Unterraum s geteilt ist. t ist eine Zwischendecke. Die Flammrohre führen von der Feuerluke zum Unterraum s, die Kanäle n vom Unterraum s bis in die Kammer p und die Kanäle o von der Kammer p bis in den Oberraum r. The side walls a, end walls b and w and bed d form the masonry. e is the boiler provided with two flame tubes f as well as manhole u and outlet v . In the masonry, two channels n running down the lower half of the boiler are formed and two channels o running down the upper half. A smoke chamber p is formed at the front and a room with a rear wall w at the back, which is divided into upper room r and lower room s by an intermediate ceiling. t is a false ceiling. The flame tubes lead from the fire hatch to the lower room s, the channels n from the lower room s to the chamber p and the channels o from the chamber p to the upper room r.

Der Planrost h liegt in einem unterhalb des Kessels befindlichen, durch Türen y zugängigen Raum g; unter dem Rost befindet sich der Ascheraum k; eine durch Hebel na von außen zu regierende Klappe 1 verdeckt den Spalt für den Schlackenabfall.The plan grate h lies in a room g located below the boiler and accessible through doors y; the ash box k is located under the grate; a flap 1 to be controlled from the outside by lever na covers the gap for the slag waste.

Unter Auflagerung auf die abgesetzten Ausläufer der Seitenwände und auf einen Eisenträger z ist ein Schacht 2 gebildet, in dessen Stirnwand 3 sich zwei Türenpaare 4 und 5 befinden. Auf der Schachtsohle lagert stufenweise zusammengesetzt der Treppenrost 6. Jede Stufe ist am Hinterrand ausschwingbar. Der Treppenrost endet vor der Feuerluke in einen Kanal ß, unter welchem der Anfang des Planrostes liegt.With support on the stepped foothills of the side walls and a shaft 2 is formed on an iron girder z, in the end wall 3 of which there are two Door pairs 4 and 5 are located. On the bottom of the shaft, it is gradually assembled the step grate 6. Each step can swing out at the rear edge. The stair grate ends in front of the fire hatch in a channel ß, under which the beginning of the plan grate is located.

Zuerst kommt die Kohle auf den Treppenrost; ist sie etwas durchgebrannt, so wechselt sie selbsttätig oder durch Rütteln der Stufen auf den Planrost über, und nun brennen zwei Feuer. Das Unterfeuer beheizt den Kessel direkt mittels Strahlung. Die Heizgase vom Treppenrost ziehen in die Flammrohre hinein und treten ebenso wie die Heizgase der Unterfeuerung im Raum s aus. Danach ziehen sie gemeinsam in :den Kanälen n wieder nach vorn, treten in die Kammer p und wandern zurück durch die Kanäle o in den Oberraum r, an welchen der Schornstein anschließt. Der Kessel wird also ständig sowohl von innen als. von unten, von außen an der Unterhälfte und von außen an der Oberhälfte beheizt und ergibt dadurch d.ie höchste Leistung bei begrenztem Brennstoffverbrauch.First the coal comes on the step grate; has she blown a little it changes automatically or by shaking the steps to the plan grate, and now two fires are burning. The underfire heats the boiler directly by means of radiation. The heating gases from the step grate pull into the flame tubes and occur as well the heating gases from the underfiring in room s. Then they move into: the Channels n forward again, enter chamber p and migrate back through the Channels o in the upper room r, to which the chimney connects. The boiler will so constantly from within as. from below, from outside on the lower half and from heated on the outside of the upper half and thus results in the highest performance with limited Fuel consumption.
