Description

Feuerungsrost Die Erfindung bezieht sich auf jene Art von Feuerungsrosten, bei .denen quer liegende, mit Öffnungen versehene Roststäbe derart aneinandergereiht sind,- daß sie Längskanäle mit zur Feuerung führenden Schlitzen bilden.Firing grate The invention relates to that type of firing grate, in the case of the transverse grate bars provided with openings lined up in this way are - that they form longitudinal channels with slots leading to the furnace.

Das Wesen der Erfindung besteht darin, daß die Roststäbe kurz vor der Feuerbrücke an Höhe zunehmen, und daß die von diesen Roststäben gebildeten Schlitze dem Zuge der Feuergase entgegen gerichtet sind. Hierdurch wird die an sich bei anderen Rosten bekannte Einführung von den Rauchgasen entgegen wirkenden Dampfluftstrahlen in einfacher Weise bei Rosten der erwähnten Gattung mit quer liegenden Roststäben erreicht.The essence of the invention is that the grate bars shortly before the fire bridge increase in height, and that the slots formed by these grate bars are directed against the course of the fire gases. This becomes the in itself with others Rust known introduction of the smoke gases counteracting steam air jets in a simple way for grates of the type mentioned with transverse grate bars achieved.

Auf der Zeichnung ist ein Ausführungsbeispiel der neuen Einrichtung in Verbindung mit einem Zweiflammrohrkessel in Abb. t in Stirnansicht und in Abb. z im Längsschnitt dargestellt.In the drawing is an embodiment of the new device in connection with a two-flame tube boiler in Fig.t in front view and in Fig. z shown in longitudinal section.

Der Rost besteht aus den bekannten, quer zur Längsrichtung der Feuerung aneinandergereihten Roststäben d, die Gruppen von Luftkanälen b bilden, wobei zweckmäßig fächerförmige Schlitze c ' nach der Oberfläche des Rostes führen. Gemäß der Erfindung sind die in der Nähe der Feuerbrücke d liegenden Roststäbe so ausgebildet, daß sie nach der Feuerbrücke zu ansteigen. Die in diesem Teil des Rostes liegenden Schlitze c sind so gekrümmt, daß die durch sie hindurchgehenden Dampf- oder Luftstrahlen von der Feuerbrücke weg, also den Rauchgasen entgegen gerichtet sind.The grate consists of the well-known, transverse to the longitudinal direction of the furnace lined up grate bars d, which form groups of air ducts b, with expedient fan-shaped slots c 'lead to the surface of the grate. According to the invention the grate bars lying in the vicinity of the fire bridge d are designed so that they to go up after the fire bridge. The slots in this part of the grate c are curved so that the steam or air jets passing through them away from the fire bridge, i.e. in the opposite direction to the smoke gases.

Um die Luft- oder Dampfzuführung zum Rost zu regeln oder Teile des Rostes ganz von der Luftzuführung absperren zu können, sind in das Dampfzuleitungsrohr e vor jedem Kanal b Regeldüsen feingebaut, durch welche die Dampf- oder Luftzuführung den Brennstoffverhältnissen entsprechend geändert werden kann.In order to regulate the air or steam supply to the grate or to be able to shut off parts of the grate completely from the air supply, control nozzles f are built into the steam supply pipe e in front of each channel b , through which the steam or air supply can be changed according to the fuel conditions.
