Description

Kühlbalken für Wanden- und Kettenroste bei Hochdruckkesseln Bei Wanden- und Kettenrosten werden zum Schutze des seitlichen Mauerwerks Balken oder Rohre gelegt, durch welche zur Kühlung Wasser hindurchigdleitet wind. Dieses Kühlwasser wird vielfach dem Oberkessel entnommen und ihm nach Durchgang durch die Kühlbalken wieder zugeführt; die seitlichen Balken stehen also dann unter Kesseldruck.Chilled beams for wall and chain gratings in high-pressure boilers. and chain gratings are used to protect the lateral masonry beams or pipes laid through which water winds for cooling. This cooling water is often taken from the upper boiler and after passing through the cooling beams fed back; the bars on the side are then under boiler pressure.

An sich sind Kühlbalken quadratischen, runden oder annähernd runden Querschnitts bekannt. Den runden Kühlbalken fehlt aber ein Abschluß gegen den Rost, durch den das Hindurchfallen von Brennstoff verhindert wird, und eine solche Ausbildung, durch die ein wirksames Tragen und Festhalten des darüberliegenden seitlichen Mauerwerkes bewirkt wird.As such, chilled beams are square, round or approximately round Cross-section known. The round chilled beams lack a seal against the grate, which prevents fuel from falling through, and such a design, through the effective carrying and holding of the overlying masonry on the side is effected.

Gemäß der Erfindung ist dagegen der im Querschnitt runde Kühlbalken mit Längsrippen versehen, die einen Abschluß der Brennbahn und eine Stützung des darüberliegenden Mauerwerkes herbeiführen.According to the invention, on the other hand, the cooling beam is round in cross section provided with longitudinal ribs that terminate the focal path and support the bring about the overlying masonry.

Die Erfindung ist in der Zeichnung im Schnitt dargestellt; es bezeichnet z den Wanderrost, 2 das seitliche Mauerwerk des Rostes, 3 dien runden Kühlbalken, q. die Längsrippen an demselben und 5 Anker, mit denen der Kühlbalken befestigt ist.The invention is shown in section in the drawing; it denotes z the traveling grate, 2 the brickwork on the side of the grate, 3 the round chilled beams, q. the longitudinal ribs on the same and 5 anchors with which the chilled beam is attached is.

Der im Querschnitt runde Kühlbalken ist, wie bekannt, außerordentlich widerstandsfähig gegenüber den hohen Drücken der Hochdruckkessel; en ist aber an sich noch nicht geeignet, die Stelle des Vierkantbalkens voll auszufüllen. Erst die erfindungsgemäß an ihm vorgesehenen Längsrippen q. befähigen ihn hierzu. Die untere Rippe soll einen dichten Abschluß gegenüber :dem Rost schaffen, damit Kohle nicht zwischen Rost und Rohr hindurchfallen kann, während die obere Rippe zur Auflagerung des Mauerwerkes dienen und ihm einen Halt ,geben soll. Abgesehen hiervon halben die Rippen noch die weitere Aufgabe zu erfüllen, den Rohrbalken zu versteifen, und zwar derartig, daß eine Verankerung nicht mehr unbedingt nötig ist. Werden jedoch aus Sicherheitsgründen dennoch Anker vorgesehen, dann werden sie auf der Rückseite des Rohrbalkens angeordnet, ohne @daß sie in das Rohrinnere eindringen und dadurch Undichtigkeiten herbeiführen können.The chilled beam, which is round in cross section, is, as is known, extraordinary resistant to the high pressures of high pressure vessels; en is on are not yet suitable to completely fill the place of the square bar. First the longitudinal ribs q provided on it according to the invention. enable him to do so. the The lower rib should create a tight seal against the grate, so that coal cannot fall through between the grate and the pipe while the upper rib is used to support it of the masonry and to give it a hold. Apart from that, half the ribs still fulfill the further task of stiffening the pipe beam, and in such a way that anchoring is no longer absolutely necessary. Will however for safety reasons anchors are still provided, then they are on the back of the pipe beam arranged without @ penetrating into the pipe interior and thereby Can cause leaks.
