Description

Vorschubrost mit zwischen festen Roststufen beweglichen Schürstufen. Bei Verbrennung insbesonders stark schlakkender Brennstoffe hat sich gezeigt, daß ein starkes Schüren und Wälzen des Brennstoffes schon am Rostanfang zu störenden Zusammenballungen des Brennstoffes und unerwünscht früher Schlackenbildung führt.Moving grate with poking steps that can be moved between fixed grate steps. In the case of burning particularly strongly lazy fuels it has been shown that a strong stoking and rolling of the fuel at the start of the grate to disturb Accumulation of the fuel and undesirably earlier slag formation leads.

Gegenstand der Erfindung ist ein Rost mit zwischen festen Stufen liegenden beweglichen Stufen, bei dem am Rostanfang die Schür-und Wälzarbeit gering, dabei die Förderwirkung verhältnismäßig groß ist, während auf dem übrigen Rost die Förderwirkung klein und die Schür- und Wälzarbeit verhältnismäßig groß ist. Diese, unterschiedliche Wirkung der Rosctteile ist durch entsprechende Anordnung der Roststufen zu erreichen.The invention relates to a grate with between fixed steps movable steps, where the stoking and rolling work is low at the start of the grate the conveying effect is relatively large, while the conveying effect is on the rest of the grate small and the stoking and rolling work is relatively large. These, different ones The effect of the rose parts can be achieved by arranging the grate steps accordingly.

In der Zeichnung ist ein Längsschnitt durch eine Dampfkesselfeuerung widergegeben. Die an die Beschickungsvorrichtung anschließende Stufenreihe mit den gegenläufig beweglichen Schürstufen a liegt und arbeitet in anderer-Richtung als die übrigen, den Hauptrost bildenden Stufen, zwischen welschen ebenfalls gegenläufig bewegliche Schürstufen b angeordnet sind, und. zwar bewegen sich die Schürstufen a in wagerechter Richtung, während die Schürstufen b und die zwischen ihnen liegenden festen Stufen schräg gegen den Feuerraum zu ansteigen.The drawing shows a longitudinal section through a steam boiler reproduced. The series of steps following the loading device with the oppositely movable poking stages a lies and works in the other direction than the other steps, which form the main grate, between which also run in opposite directions movable poking stages b are arranged, and. although the stoves move a in the horizontal direction, while the stoking levels b and between fixed steps lying on them to rise diagonally towards the combustion chamber.

Im ersten Teil des Rostes mit den Schürstufen a findet ein Vortrocknen und Anbrennen des frisch zugeführten Brennstoffes statt unter gleichzeitigem Vorschieben desselben gegen den Hauptverbrennungsros.t zu. Ein wesentliches Schüren und Wälzen des Brennstoffes ist durch die Lage der Stufen und Schürroste a vermieden. Die Größe dieses Vorrostes wird so gewählt, daß an seinem Ende ungefähr die Verschlackung beginnt. In diesem Zeitpunkt ist zur Vermeidung großer zusammenhängender Schlackenbrocken ein starkes Wälzen der Brennstoffschicht notwendig, was durch den zweiten Teil des Rostes erzielt wird. Die schräg ansteigenden und bewegten Stufen b bewirken im Zusammenhang mit der rückwärts gerichteten Böschungstendenz des Brennstoffes ein starkes, insbesondere rückwärts gerichtetes Wälzen der Massen., so daß die Schlacken kleinkörnig ausgetragen werden. Durch die Wahl der gegenseitigen Stufen am Vor- und Hauptrost hat man es in der Hand, die `Virkung jeder Brennstoffart anzupassen.Pre-drying takes place in the first part of the grate with stoking levels a and burning the freshly supplied fuel instead of simultaneously advancing it the same against the main combustion engine. An essential stoking and rolling of the fuel is avoided by the position of the steps and poking grates a. The size this pre-grate is chosen so that approximately the slagging at its end begins. At this point it is important to avoid large, contiguous lumps of cinder a strong rolling of the fuel layer is necessary, which is caused by the second part of the Rust is achieved. The inclined and moving steps b cause in connection with the backward slope tendency of the fuel a strong, in particular backward rolling of the masses, so that the slag is discharged in small grains will. You have it by choosing the mutual steps on the front and main grating in hand to adapt the effect of each type of fuel.

Der Antrieb der Schürstufen. kann in bekannter Weise durch Zahnstangen und Zahnräder oder Zahnsegmente oder aber auch durch Hebelübersetzuüg bewirkt werden..The drive of the stoves. can in a known manner by means of racks and gearwheels or toothed segments or also by lever transmission.
