Description

Gaserzeuger-Treppenrost mit Ringplatten. Der Treppenrost gemäß der Erfihdung ist eine weitere Ausbildung des durch Patent 31399.4 geschützten Gaserzeuger-Treppenrostes. Es hat sich herausgestellt, daß bei der Ausbildung dieses Rostes mit flachen Ringplatten, insbesondere init nur einer einzigen Ringplatte und darunterliegender Vollplatte gemäß Abb. :2 des genannten Patentes, die Kohlensäure im Kern zu geringe Glut aufwies und das Feuer an den Seiten zu leicht hochbrannte. Der Übelstand wurde erkannt als herrührend von den verschiedenen Widerständen, die die Luft beim Eintritt zwischen der Rin- latte und der Unterkante des .,p Schachtes einerseits und zwischen den beiden Platten anderseits zu überwinden hatte. Gemäß Abb. i, die die alte Ansführting wiedergibt. bestimmt sich der Widerstand der in die Oberschicht eintretenden Luftsäule ans der Länge a, der Widerstand der unten eintretenden Luft ans der Länge b unter Zu-Mindelegung eines mittleren Austrittsquerschnitts der Luft ans der oberen Kohlenscbicht unterhalb des Fülltrichters. Gemäß der vorliegenden Verhesserting wird die durchlochte Rostplatte C (Abb. 2) in ihrem mittleren Teil so weit erhöht., daß die Oberkante der Kohlenböscbung zwischen dieser Platte und der unteren Vollplatte D ganz oder nahezu die Höhe der Oberkante der Kohlenböschung zwischen Schachtunterkante und oberer Ringplatte erreicht. -Man erkennt sofort, daß auf diese Weise die -Masse a. b ganz oder nahezu gleich geworden sind. Tatsächlich hat sich gezeigt, daß diese Änderting der Gestalt von günstigem Einfluß auf die Verbrennung im Gaserzeu-er ist, so (laß nuntnehr die Kohlenschicht gleichmäßig durchglüht niedersinkt.Gas generator step grate with ring plates. The step grating according to the invention is a further development of the gas generator step grating protected by patent 31399.4. It has been found that when this grate was designed with flat ring plates, in particular with only a single ring plate and a solid plate underneath according to Fig . The inconvenience was recognized as originating from the various resistances which the air had to overcome when entering between the lath and the lower edge of the., P shaft on the one hand and between the two plates on the other. According to Fig. I, which reproduces the old listing. the resistance of the air column entering the upper layer is determined by length a, the resistance of the air entering below is determined by length b, with a mean outlet cross-section of the air being reduced to the upper carbon layer below the filling funnel. According to the present Verhesserting, the perforated grate plate C (Fig. 2) is increased in its middle part so much that the upper edge of the coal slope between this plate and the lower solid plate D is completely or almost the height of the upper edge of the coal slope between the lower edge of the shaft and the upper ring plate achieved. You can see immediately that in this way the mass a. b have become completely or almost the same. In fact, it has been shown that this change in shape has a favorable influence on the combustion in the gas generator, so now let the coal layer sink down, evenly glowing through.
