Description

Kühleinrichtung für die Brennkammer von Kohlenstaubfeuerungen Die Erfindung betrifft eine Kühleinrichtang für die Brennkammer von Kohlenstaubfeuerung@en. Kühleinrichtungen dieser Art, bei denen gleichzeitig Luft- und Wasserkühlung angewendet wird, sind an sich bekannt. Nach der Erfindung wird als Kühleinrichtung eine Luft- und Wasserkühlung in der Weise verwendet, daß die den zwischen der Innenwand der Brennkammer und ihrer Außenverkleidung gebildeten Schacht durchströmende Kühlluft gleichzeitig die in Kanälen des Mauerwerks eingebauten Wasserrohre allseitig umspült; ermöglicht wird dies dadurch, daß die die Wasserrohre enthaltenden Kanäle nach der Schachtseite zu of .en sind.Cooling device for the combustion chamber of pulverized coal furnaces Die The invention relates to a Kühleinrichtang for the combustion chamber of coal dust firing systems. Cooling systems of this type, in which air and water cooling are used at the same time are known per se. According to the invention, an air is used as the cooling device and water cooling used in such a way that the between the inner wall of the Combustion chamber and its outer cladding formed shaft cooling air flowing through at the same time, the water pipes installed in the masonry channels were washed around on all sides; this is made possible by the fact that the channels containing the water pipes after Shaft side to be open.

In der Zeichnung ist die Erfindung in zwei Ausführungen dargestellt, und zwar veranschaulichen Abb. i einen Längsschnitt der Brennkammer und Abb. z einen Querschnitt einer Mauerwand. Die Wandungen der Brennkammer a bestehen- in bekannter Weise aus einer aus Mauerwerk gebildeten Innenwand 4 sowie einer durch einen Luftschacht 6 getrennten Stahlummantelung 5 als Außenverkleidung. Zwischen der Innenverkleidung 4 und dem Stahlmantels sind in Kanälen des Mauerwerks 4 Wasserrohre i eingebaut, die durch Wasserkammern 3 gespeist werden. Die Kanäle -des Mauerwerks stehen mit dem Luftschacht 6 in Verbindung, so daß die Rohre von der die Wandung durchströmenden Kühlluft allseitig umspült werden.In the drawing, the invention is shown in two versions, namely, Fig. i illustrate a longitudinal section of the combustion chamber and Fig. z a Cross section of a wall wall. The walls of the combustion chamber a are known Way from an inner wall 4 formed from masonry and one through an air shaft 6 separate steel cladding 5 as external cladding. Between the interior trim 4 and the steel jacket 4 water pipes i are installed in channels of the masonry, which are fed by water chambers 3. The channels of the masonry are with the air shaft 6 in connection, so that the pipes from the wall flowing through Cooling air are flushed around on all sides.
