Description

Verfahren und Einrichtung zum Anlassen von 14ohlenstaubfeuerungen. Beim Anlassen von Kohlenstau.bfeuerungen ergeben sich häufig dadurch Schwierigkeiten, daß die noch kalten Wände des Feu.erungsraumes einen großen Teil der durch eine Zündflamme zugeführten @Värme aufnehmen, so daß der Brennstoff schwer zum Zünden zu. bringen ist.Method and device for starting coal dust firing systems. When starting dammed coal fires, this often results in difficulties that the still cold walls of the furnace room made up a large part of the Ignition flame supplied @ absorb heat so that the fuel is difficult to ignite to. bring is.

Dieser Nachteil wird durch die Erfindung vermieden. Erfindungsgemäß wird die Düse so mit schirmenden Wänden umgeben, daß ein Abstrahlen der durch die Zündflamme zugeführten Wärmne auf die Heizflächen verhindert wird. Die Wärme wird dadurch in einem kleinen Raum zusammengehalten und der Verbrennungsraum in kurzer Zeit auf die zur Zündung des Brennstoffes erforderliche Temperatur gebracht.This disadvantage is avoided by the invention. According to the invention the nozzle is so surrounded with shielding walls that the radiation through the Ignition flame supplied heat is prevented on the heating surfaces. The heat will thus held together in a small space and the combustion chamber in a short time Time brought to the temperature required to ignite the fuel.

Zur Durchführung des Verfahrens ist zwischen der Brennstoffdüse und der Heizfläche ein verstellbares Wehr angeordnet, das beim Zünden heruntergelassen wird und im Verein mit den Wänden des, Verbrennungsraumes eine besondere kleine Zündkammer bildet, die sich schnell erwärmen läßt. Man kann an Stelle des beweglichen. auch ein festes Wehr anordnen und die Düse beweglich machen. Sie wird dann, beim Zünden in die von dem festen Wehr abgegrenzte Kammer zurückgezogen und später, wenn sich die Flamme voll entwickelt hat, weiter vorgeschoben, so daß die Heizfläche von der strahlenden Wärme der Flamme voll getroffen wird.To carry out the process is between the fuel nozzle and the heating surface arranged an adjustable weir, which when Ignite is lowered and in conjunction with the walls of the combustion chamber a Forms a special small ignition chamber that can be heated up quickly. One can at Place of the movable. also arrange a fixed weir and make the nozzle movable. When it is ignited, it is then withdrawn into the chamber delimited by the fixed weir and later, when the flame has fully developed, further advanced so that the heating surface is fully hit by the radiant heat of the flame.

Die Erfindung ist m einer Ausführungsform in der Zeichnung veranschaulicht.The invention is illustrated m one embodiment in the drawing.

i ist der Verbrennungsraum der Kohlenstaubfenerumg, 2 die Heizfläche, z. B. ein Wasserrohrkessel; 3 ist das verstellbare Wehr und q. die Brennstoffdüse.i is the combustion chamber of the coal dust furnace, 2 the heating surface, z. B. a water tube boiler; 3 is the adjustable weir and q. the fuel nozzle.

'Die Anordnung kann gleichzeitig dazu verwendet werden, die Temperatur in gewissen Grenzen zu regeln, indem man die Flamme mehr oder weniger gegen die Heizfläche abschirmt.'The arrangement can also be used to measure the temperature to regulate within certain limits by placing the flame more or less against the Shields the heating surface.
