Description
Roststab für die Seitenwände bei Zentralbeizungskesseln. In dem Patent 342925 ist ein Zentralheizungskessel mit Feuerkorb beschrieben, bei dem an den Seiten des Feuerraumes Roststäbe bzw. Schutzstäbe angeordnet sind, welche den Brennstoffklotz vor der ummittelbaren Berührung mit den wassergekühlten Heizflächen schützen. Diese Einrichtung hat den Zweck, eine hohe Verbrennungstemperatur zu gewährleisten, wodurch die Verbrennung vollkommener und die Ausnutzung des Brennstoffes besser wird. Um nun die Verbrennungstemperatur möglichst hoch und die Verbrennung so vollständig wie möglich zu gestalten, sind nach dem vorliegenden Zusatzpatent die an den Seiten des Feuerraumes befindlichen Roststäbe, die aus einem mit feuerfester Masse umhüllten Metallkern bestehen, hohl ausgeführt und mit seitlichen Durchbrechungen versehen, damit Sekundärluft zugeführt werden kann, die in den heißen Stäben vorgewärmt und durch die in verschiedener Höhe ausmündenden Durchbrechungen dem Feuer gleichmäßig verteilt zugeführt werden kann. In der Zeichnung ist ein seitlicher Roststab dargestellt. a ist der rohrförmige Metallkern, b die Umhüllung mit feuerfester Masse; c sind seitliche Durchbrechungen. Die Sekundärluft kann von unten entweder aus dem Kesselraum d oder dem Aschenfall c oder von beiden Stellen zutreten. Die Stäbe können, wie punktiert angedeutet ist, leicht eingesetzt bzw. ausgewechselt werden.Grate bar for the side walls of central pickling boilers. In the patent 342925 describes a central heating boiler with a fire basket, in which on the sides of the combustion chamber grate bars or protective bars are arranged, which the fuel block Protect against direct contact with the water-cooled heating surfaces. These The purpose of the facility is to ensure a high combustion temperature, which means combustion is more perfect and fuel utilization is better. Around Now the combustion temperature is as high as possible and the combustion is so complete as possible are, according to the present additional patent, those on the sides grate bars located in the combustion chamber, which are covered with a refractory mass Consist of a metal core, made hollow and provided with lateral perforations, so that secondary air can be supplied, which is preheated and in the hot rods through the breakthroughs opening out at different heights, the fire evenly can be supplied distributed. A lateral grate bar is shown in the drawing. a is the tubular metal core, b is the refractory coating; c are lateral openings. The secondary air can either come from below from the boiler room d or the ash fall c or from both places. The rods can, like is indicated by dotted lines, can be easily inserted or exchanged.
