Description

Schüttfeuerung mit über den Rosten angeordneten, von den Füllschachtwänden begrenzten Gaskammern, insbesondere für Rohbraunkohle Die Erfindung betrifft Schüttfeuerungen mit über den Rosten angeordneten, von den Füllschachtwänden begrenzten Gaskammern, insbesondere für Rohbraunkohle. Das Wesen der Erfindung besteht darin, daß in der Querrichtung des Feuerraumes mechanisch bewegbare Treppen- oder Sattelroste mehrreihig übereinander und versetzt zueinander eingebaut sind, wobei jeder Rost durch ein eine Brennkammer bildendes Gewölbe überdeckt ist und die Seitenwände der Brennkammergewölbe gesonderte Füllschächte für die einzelnen Roste bilden.Bulk firing with over the grates arranged from the hopper walls limited gas chambers, especially for raw lignite. The invention relates to bulk firing systems with gas chambers arranged above the grates and delimited by the filling shaft walls, especially for raw lignite. The essence of the invention is that in the Mechanically movable stair or saddle grates in multiple rows across the combustion chamber are installed one above the other and offset from one another, with each grate through a a vault forming a combustion chamber is covered and the side walls of the combustion chamber vault Form separate filling shafts for the individual grids.

Durch diese Ausbildung der Feuerung wird die Anzahl der Brennstellen erhöht, ohne daß eine Verbreiterung der Feuerung nötig wird. Man erzielt also bei gleicher Raumbeanspruchung eine höhere Rostleistung als bei den bekannten Feuerungen.This design of the furnace increases the number of burners increased without the need to broaden the furnace. So you get at the same space requirement, a higher grate capacity than with the known furnaces.

Auf der Zeichnung ist der Gegenstand der Erfindung beispielsweise dargestellt.In the drawing, the subject of the invention is for example shown.

Fig. i ist ein senkrechter Querschnitt, Fig.2 ein senkrechter Längsschnitt nach Linie A-B in Fig. i.Fig. I is a vertical cross section, Fig. 2 is a vertical longitudinal section according to line A-B in Fig. i.

In dem Ausführungsbeispiel sind über zwei nebeneinanderliegenden Sattelrosten, die aus je zwei Schrägrosten a bestehen, gleichartige Sattelroste b angeordnet. Die Roste b sind gegenüber den Rosten a versetzt. jeder Schrägrost ist durch ein Gewölbe c überdeckt, welches eine Brennkammer bildet.In the exemplary embodiment, there are two adjacent saddle grids, which each consist of two inclined grids a, arranged similar saddle grates b. The grids b are offset from the grids a. each inclined grate is through one Vault c covers, which forms a combustion chamber.

Der Brennstoff wird den Rosten a durch die Kanäle d, den Rosten b durch die Kanäle e zugeführt. Diese Kanäle werden von den Seitenwänden der Brennkammergewölbe gebildet. Der Abschluß eines jeden Schrägrostes besteht aus einem drehbaren, geteilten Schlakkenrost f.The fuel is fed to the grate a through the channels d and the grate b through the channels e. These channels are formed by the side walls of the combustion chamber vault. The conclusion of each inclined grate consists of a rotatable, split slag grate f.

Die zu den oberen Rosten b strömende Verbrennungsluft wird durch die Gewölbe c vorgewärmt, wodurch die Verbrennung günstig beeinflußt wird. Andererseits strahlen die Gewölbe Wärme auf den auf den Rosten liegenden Brennstoff aus.The combustion air flowing to the upper grids b is through the Vault c preheated, whereby the combustion is favorably influenced. on the other hand the vaults radiate heat to the fuel lying on the grates.

Die Verbrennungsrückstände der oberen Roste werden über die unteren Roste der Schlackenkammer zugeführt. Hierdurch wird auch die Verbrennung derjenigen Brennstoffteile gewährleistet, die etwa unverbrannt die oberen Roste verlassen haben sollten.The combustion residues from the upper grates are transferred to the lower grids Grids fed to the slag chamber. This also causes the burning of those Guaranteed fuel parts that have left the upper grates unburned should.

In der Zeichnung sind zwei Rostreihen übereinander angeordnet, man kann aber auch mehr als zwei übereinanderliegende Rostreihen verwenden.In the drawing, two rows of grids are arranged one above the other, man but can also use more than two rows of grids on top of each other.
