BESCHREIBUNG Heat generator
DESCRIPTION

Die Neuerung betrifft einen Vlärmeer zeuger mit einer Feuerung, einem von der Feuerung befeuerten Flammrohr, mindestens einem Rohrzug zum Abziehen der Verbrennungsgase sowie einem Außenmantel. The innovation concerns a noise generator with a firing system, a flame tube fired by the firing system, at least one pipe pass for extracting the combustion gases and an outer casing.

Bekannt ist, die Rauchgasrückführung in einem vom Wärmeerzeuger getrennt verlaufenden Kanal vorzunehmen. Dies hat den Nachteil, daß einmal umständliche und teure Kanäle erstellt werden müssen und der rückgeführte Abgasstrom in seiner Temperatur nicht abgesenkt werden kann, cbwohl eine verminderte Temperatur dieser rückgeführten Abgase ebenfalls zur Reduzierung des NO -Gehal-It is known that the flue gas recirculation takes place in a channel that runs separately from the heat generator. This has the disadvantage that complicated and expensive channels have to be created and the temperature of the recirculated exhaust gas flow cannot be reduced, although a reduced temperature of these recirculated exhaust gases also helps to reduce the NO content.

tes der Verbrennun^sgase beitragen würde.tes of the combustion gases.

Um diesen Nachteil zu beseitigen, wird erfindungsgemäß vorgeschlagen, den Abgaskanal zur Rückführung der Abgase so anzuordnen, daß dieser innerhalb des Wärmeerzeugers oder entlang seiner Wandung auf kurzem Weg zur Feuerung und so verläuft, daß Wärme der Abgase an den Wärmeträger - vornehmlich Wasser - abgegeben und damit die Temperatur der vor Eintritt in die Feuerung abgesenkt wird.In order to eliminate this disadvantage, it is proposed according to the invention to arrange the exhaust gas duct for returning the exhaust gases in such a way that it runs within the heat generator or along its wall on a short path to the furnace and in such a way that heat from the exhaust gases is transferred to the heat carrier - primarily water - and thus the temperature is lowered before entering the furnace.

In Fig. 1 und Fig. 2 wird ein Beispiel einer derartigen Anordnung dargestellt.An example of such an arrangement is shown in Fig. 1 and Fig. 2.

Die Verbrennungsgase, herrührend von der Feuerung 1 gelangen in den Abgaskasten 2. Ein Teilstrom der Abgase wird über das Rohr 3, welches innerhalb des WasserraumesThe combustion gases, originating from the furnace 1, enter the exhaust box 2. A partial flow of the exhaust gases is discharged via the pipe 3, which is located within the water chamber
