 geringen Luftmenge (mit der sogenannten theoretischen Luftmenge) vollkommene Verbrennung zu erreichen. In der Tat haben vergleichende Versuche ergeben, dass eine Rostplatte der vorstehend beschriebenen Art   bei   nur 2% freier Durchgangsfläche bei einfachem Schornsteinzug nicht nur die mit   Unterdruck funktionierende Kudlicz-Feuerung,   sondern auch einen Rost, welcher   450/0   freie Durchgangsfläche hat, in ökonomischer Hinsicht und in Rauchfroiheit der Verbrennung selbst unter sehr ungünstigen Verhältnissen wesentlich übertrifft.'

Zugleich ist es wahrscheinlich empfehlenswert die unteren Kanten zwischen den einzelnen Düsen möglichst schmal (scharfkantig) zu machen, damit die Luft sich daran möglichst

   Besonders vorteilhaft erscheint es, die Düsengruppe in besondere Einsatzplättchen a' (Fig. 4 und 4a) zu vereinigen, welche sich mittelst einiger schmaler Ansätze c gegen

   PATENT-ANSPRÜCHE : 
1.   Filr   einfachen Schornsteinzug bestimmter Rost, in welchem durch grössere undurchbrochene Flächen voneinander getrennte kleine Roststellen je eine Gruppe von mehrfach um je einen Mittelpunkt herum angeordneten, annähernd düsenförmigen Öffnungen besitzen.

 low air volume (with the so-called theoretical air volume) to achieve perfect combustion. In fact, comparative tests have shown that a grate plate of the type described above with only 2% free passage area with a simple chimney draft not only the Kudlicz furnace, which works with negative pressure, but also a grate which has 450/0 free passage area, in economic terms and in terms of smoke-free combustion, even under very unfavorable conditions, is considerably superior.

It is important to carry out

   the individual narrow through openings
 EMI2.2
 this is easily possible with direct penetrations of the entire plate thickness; in the case of thicker panels, however, there is the need to reduce the panel thickness at the group points themselves, as is indicated in FIGS. 2, 3 and 4 at a and a '. At the same time, it is probably advisable to make the lower edges between the individual nozzles as narrow as possible (sharp-edged) so that the air can be as possible
 EMI2.3
 or uneven distribution of the nozzles - with crowding towards the center - as indicated in FIG. 2, probably more advantageous than an even distribution of the nozzles according to FIG. 3.



   It appears to be particularly advantageous to combine the group of nozzles in special insert plates a '(FIGS. 4 and 4a), which counteract by means of a few narrow extensions c

   PATENT CLAIMS:
1. A grate defined for a simple chimney draft, in which small grate areas separated from one another by larger uninterrupted surfaces each have a group of approximately nozzle-shaped openings, which are arranged several times around a center point.
