Description

Feuerung mit mehreren Kohlenzuführungsschächten Die Erfindung, erstreckt sich auf Muldenrostfeuerungen, bei welchen der Gesamtfeuerraum in einzelne parallel zueinander liegende Brennkammern mit zwischengeschalteten Kohlenzuführungsschächten unterteilt ist.Multiple coal feed duct furnace The invention extends on hollow grate firing, in which the entire firebox is divided into individual parallel Combustion chambers lying opposite one another with interposed coal supply shafts is divided.

Von den bekannten Feuerungen dieser Art unterscheidet sich die den Gegenstand der Erfindung bildende Feuerung dadurch, daß in den einzelnen Brennkammern durch Einbau einer mittleren Längswand zwei voneinander unabhängige Feuerräume gebildet werden. Hierdurch wird der Vorteil erreicht, daß diese Trennwand die von ihr aufgenommene Wärme auf die ihr gegenüberliegenden feuerfesten Wände der Zuführungsschächte ausstrahlt und somit die Vortrocknung des den Rosten zufließenden Brennstoffes begünstigt.The den differs from the known firing systems of this type The subject of the invention forming furnace characterized in that in the individual combustion chambers By installing a central longitudinal wall, two independent combustion chambers were created will. This has the advantage that this partition is the one received by it Radiates heat on the opposite refractory walls of the feed shafts and thus favors the pre-drying of the fuel flowing into the grates.

In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt.In the drawing, the subject matter of the invention is in one embodiment shown.

Hiernach besteht die Rostfeuerungsanlage aus mehreren sattelförmigen, nebeneinanderliegenden Treppenrosten a, die durch über ihren Scheiteln angeordnete trichterförmige Zuführungsschächte d, e mit Brennstoff beschickt werden. Zwischen den einzelnen Zuführungsschächten sind Brennkammern b vorgesehen, die durch je eine mittlere Längswand c in zwei voneinander unabhängige Brennräume unterteilt werden. Die Trennwände c strahlen dann die aus den Feuergasen aufgenommene Wärme auf die feuerfesten Schachtwände aus und unterstützen hierdurch wesentlich die Vortrocknung der durch die Schächte niederrieselnden Kohle, so daß auch minderwertige Brennstoffe, wie Braunkohle o. dgl. bei größtmöglicher Ausnutzung der Heizfläche verfeuert werden können.According to this, the grate firing system consists of several saddle-shaped stepped grates a lying next to one another, which are fed with fuel through funnel-shaped feed shafts d, e arranged above their apexes. Combustion chambers b are provided between the individual feed shafts, each of which is subdivided into two independent combustion chambers by a central longitudinal wall c. The partition walls c then radiate the heat absorbed from the fire gases onto the refractory shaft walls and thereby significantly support the pre-drying of the coal trickling down through the shafts, so that even inferior fuels such as lignite or the like can be burned with the greatest possible utilization of the heating surface.

Die verwendeten Sattelroste a können naturgemäß in beliebiger Weise ausgebildet werden. Zweckmäßig wird man sogenannte Vorschub-, Schüttel- oder Kipptreppenroste einbauen.The saddle grids used a can of course in any way be formed. So-called feed, shaking or tilting stair gratings are expedient build in.
