Description
Feuerung mit durch Feuergase beheiztem Zusatzlufterhitzer. Die Erfindung erstreckt sich auf eine Verbesserung der Feuerung mit durch Feuergase beheiztem Zusatzlufterhitzer nach Patent 4z 5 5 59, bei welcher hinter der Feuerbrücke in Abstand davon ein ,gemauerter Schlangenweg # für die Feuergase angelegt ist, durch welchen dünnwandige Luftrohre gelegt sind, die teils in der Vorderwand der Feuerbrücke, teils in den Seitenwänden und der Decke des Feuerraumes ausmünden.Firing with an additional air heater heated by fire gases. The invention extends to an improvement of the combustion with heated by fire gases Additional air heater according to patent 4z 5 5 59, in which behind the fire bridge in Distance from this is a brick snake path # for the fire gases is laid through which thin-walled air pipes are placed, some of which are in the front wall of the fire bridge, partly open into the side walls and the ceiling of the firebox.
Es hat sich als notwendig erwiesen, die durch den Zusatzlufterhitzer erzeugte Heißluft zum größten Teil vor dem Rost und dort ausblasen zu lassen, wo sich der frische Brennstoff mit dem in Glut befindlichen Brennstoff berührt. Zu diesem Zweck ist in der Feuerbrücke ein Sammelkanal für die Heißluft angeordnet, der durch Mauerwerkskanäle mit einem quer über der FeuertüröffnunZ. in der Feuerraumvorderwand verlegten und mit Düsen in den Feuerraum mündenden Kanal verbunden ist.It has been found necessary to use the auxiliary air heater to let the generated hot air blow out for the most part in front of the grate and wherever the fresh fuel comes into contact with the ember fuel. to For this purpose, a collecting duct for the hot air is arranged in the fire bridge, through masonry ducts with a cross over the fire door opening. in the front wall of the combustion chamber laid and connected to the duct opening into the combustion chamber with nozzles.
In der Zeichnung ist eine Ausführungsform der Erfindung dargestellt, und zwar zeigt Abb. i die .neue Feuerung im Längsschnitt und Abb. z einen Schnitt durch den quer vor dem Rost liegenden Kanal.In the drawing, an embodiment of the invention is shown, Fig. i shows the new furnace in a longitudinal section and Fig. z shows a section through the canal lying across in front of the grate.
In der Feuerbrücke e ist ein Hohlraum 'angeordnet, in welchem sich die Heißluft ansammelt. Diese strömt dann zu beiden Seiten des Rostes a durch Mauerwerkskanäle hl, welche mit einem quer vor dem Rost und über der Feuertüröffnung in der Feuerraumvorderwand verlegten und mit in den Feuerraum mündenden Düsen f versehenen Kanal h2 in Verbindung stehen.In the fire bridge e is a cavity 'arranged in which the hot air accumulates. This then flows on both sides of the grate a through masonry channels hl, which with a cross in front of the grate and above the fire door opening in the front wall of the combustion chamber The channel h2 laid and provided with nozzles f opening into the combustion chamber stand.
Um mittels hoher Glutschicht hohe Temperaturen zu erzeugen, läßt man etwas Heißluft aus der hohlen Feuerbrücke durch die Düsen f 1 unter den Rost blasen, wodurch über der Glut heiße Kohlenoxydgase entstehen, welche mit der heißen Oberluft zusammen bei der Verbrennung Temperaturen bis zu zooo° C erzeugen,. Die Düsen /l können durch eine Klappe p geregelt werden.In order to generate high temperatures by means of a high layer of embers, one leaves blow some hot air from the hollow fire bridge through the nozzles f 1 under the grate, whereby hot carbon dioxide gases arise over the embers, which with the hot upper air together generate temperatures of up to zooo ° C during combustion. The nozzles / l can be regulated by a flap p.
Um die Oberluft aus mehr oder weniger Düsenreihen austreten zu lassen, sind im Innern des Luftkanals hl (Abb. z) walzenartige Verschlüsse drehbar gelagert.In order to let the upper air exit from more or less rows of nozzles, are rotatably mounted inside the air duct hl (Fig. z) roller-like closures.
Da sich bei dieser Feuerung ein Abschlacken des Rostes erübrigt, liegt er unterhalb der Sohle der Feuertür, damit Platz für .den mit Düsen versehenen Luftkanal quer vor dem Rost geschaffen wurde.Since slagging off the grate is unnecessary with this type of firing, this is the case it is below the bottom of the fire door, so there is space for the air duct with nozzles was created across in front of the grate.
