Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Nach der Erfindung soll dadurch eine rauchfreie Verbrennung herbeigeführt werden, dafs die zur Verbrennung erforderliche Luft nicht nur von unten durch die Rostspalten, sondern auch oberhalb der Rostfläche von der Seite her der Brennstoffschicht zugeführt wird. Zu diesem Zwecke wird die Rostfläche seitlich und gegebenenfalls auch hinten von durchbrochenen Wänden oder Kästen begrenzt, durch deren Oeffnungen die von aufsen zugeführte Luft seitlich in die Brennstoffschicht eingeführt wird.According to the invention, smoke-free combustion is to be brought about by the fact that the air required for combustion not only from below through the grate gaps, but is also fed to the fuel layer from the side above the grate surface. to For this purpose, the grate surface is perforated laterally and possibly also at the rear Walls or boxes, through whose openings the one supplied from the outside Air is introduced laterally into the fuel layer.

In den Fig. 1 bis 6 sind verschiedene Ausführungsformen einer derartigen Feuerungsanlage veranschaulicht, deren erste eine Innenfeuerung für kleinere Flammrohre darstellt.In FIGS. 1 to 6 there are different embodiments illustrates such a furnace, the first of which is an internal furnace for smaller flame tubes.

Der Rost wird hierbei durch am unteren Theil waagerecht gestaltete, nach oben hin schräg ansteigende Roststäbe α gebildet, welche jedoch nicht die ganze Breite des Flammrohres einnehmen. Der untere waagerechte Theil der Rostfläche wird durch eine aufrecht stehende, gitterförmig durchbrochene Platte b begrenzt, die an dem Rostträger c ihre Auflage findet und von einer theilweise über die Rostfläche vorspringenden Platte d überdeckt wird. Die letztere bewirkt, dafs die durch die Oeffnungen der Platte b seitlich eintretende Luft nicht nach oben entweichen kann, sondern die Brennstoffschicht nahe der Oberfläche durchziehen mufs. Diese Luft trägt infolge dessen nicht nur dazu bei, die Verbrennung zu fördern, sondern sie ruft auch oberhalb der Rostfläche eine Nachverbrennung hervor, die eine wirksame Rauchverzehrung bedingt. The grate is formed here by grate bars α which are horizontally designed on the lower part and rise obliquely towards the top, but which do not occupy the entire width of the flame tube. The lower horizontal part of the grate surface is delimited by an upright, lattice-shaped perforated plate b which is supported on the grate support c and is covered by a plate d which partially protrudes over the grate surface. The latter has the effect that the air entering laterally through the openings in the plate b cannot escape upwards, but has to pass through the fuel layer near the surface. As a result, this air not only helps to promote combustion, but also causes post-combustion above the grate surface, which causes effective smoke consumption.

Bei der in den Fig. 4 bis 6 dargestellten, für gröfsere Flammrohre bestimmten Ausführungsform ist der Rost als,sogenannter Sattelrost ausgeführt, der beiderseits von durchbrochenen Platten b begrenzt und durch vorspringende Platten d überdeckt ist.In the embodiment shown in FIGS. 4 to 6 intended for larger flame tubes, the grate is designed as a so-called saddle grate, which is delimited on both sides by perforated plates b and covered by protruding plates d .
