Description

Verfahren zur Nutzbarmachung des in Sammelräumen der Rauchgaszüge aufgefangenen Flugkokses @ durch Rückführung in den Feuerraum Bei Feuerungen ist es bereits bekannt, Rauchgase in den Feuerraum zurückzuführen. Ferner ist es vorgeschlagen worden, Flugkoks und andere brennbare Rückstände aus einem Sammeltrichter durch einen Druckluftstrom in die Feuerkammer zurückzuführen.Process for utilizing the in the collecting areas of the flue gas ducts caught flycoke @ by returning it to the combustion chamber it is already known to return flue gases to the combustion chamber. It is also proposed fly coke and other flammable residues from a collecting hopper return a stream of compressed air to the firebox.

Der Erfindung gemäß werden zur Rückführung und damit zur Nutzbarmachung des Flugkokses an Stelle des Druckluftstromes als ausschließliches Treibmittel heiße Rauchgase benutzt, die mittels eines Gebläses aus den Rauchzügen angesaugt und den Sammelräumen durch eine Blasdüse zugeführt werden. Dies hat zweierlei Vorteile: Die heißen Flugkoksteile, welche in den Sammeltrichtern der Kesselanlage zur Abscheidung gelangen, werden hierbei nicht wie bei dem Einblasen mit kalter Luft abgekühlt. Sie sind daher im Feuerraum schneller brennfähig und gelangen dadurch zur vollkommenen Verbrennung, ehe sie wieder mit den Siederohren des Kessels in Berührung kommen. Ferner wird beim Einblasen mit Rauchgasen ein zu großer Luftüberschuß im Feuerraum vermieden. Man ist nicht an eine bestimmte Mindestmenge des Fördermittels für den Flugkoks gebunden, und man kann eine so große Menge von Rauchgasen einblasen, daß der Rauchgasstrom gleichzeitig eine Durchwirbelung des Feuergases im Feuerraum bewirkt, wodurch der gesamte Verbrennungsvorgang verbessert wird.According to the invention are for recycling and thus for utilization hot air coke instead of the compressed air flow as the exclusive propellant Flue gases are used, which are sucked in from the flues by means of a fan and the Collection spaces are fed through a blower nozzle. This has two advantages: The hot parts of the fly coke, which are deposited in the collecting hoppers of the boiler system are not cooled down with cold air as they are when blown in. They are therefore more quickly combustible in the combustion chamber and thus achieve perfect Burn before they come into contact with the boiler pipes again. Furthermore, when the flue gases are blown in, there is too much excess air in the furnace avoided. One is not required to have a certain minimum amount of funding for that Aircraft coke bound, and you can blow in such a large amount of flue gases that the flue gas flow simultaneously causes the fire gas to be swirled in the combustion chamber, whereby the entire combustion process is improved.

In der Zeichnung ist eine Ausführungsform einer Einrichtung zur Ausführung des Verfahrens in Verbindung mit einer Wanderrostkesselfeuerung beispielsweise dargestellt.In the drawing is an embodiment of a device for execution of the method in connection with a traveling grate boiler, for example.

a ist der Wanderrost, an dessen Stelle natür-]ich auch eine andere Rostfeuerung vorgesehen sein könnte. b ist der unterhalb der Feuerbrücke angeordnete Schlackenstauer, c der Feuerraum. In dem Kesselzug ist ein Sammeltrichter d für die aus den Rauchgasen anfallenden Flugkoksteile eingeschaltet. Es können auch mehrere solcher Trichter, beispielsweise auch noch ein Trichter in dem Raum e vorgesehen sein. Der Sammeltrichter d ist unten mit einem Absperrschieber f versehen, der durch eine Zugstange g von außen eingestellt werden kann.a is the traveling grate, in its place of course I also have another Grate firing could be provided. b is the one below the fire bridge Cinder block, c the combustion chamber. In the boiler pass is a collecting funnel d for switched on the flycoke particles arising from the flue gases. There can be several such funnel, for example also a funnel, is provided in space e be. The collecting funnel d is provided at the bottom with a gate valve f, which through a pull rod g can be adjusted from the outside.

Durch ein Rohr,h ist jeder Trichter an eine zur Druckseite eines Gebläses k führende Leitung i angeschlossen, an dessen. Saugseite sich ein Saugrohr x anschließt. Dieses mündet in dem hinteren Teil des Kesselzuges, jedenfalls aber dort, wo heiße, bereits von dem Flugkoks befreite Rauchgase vorhanden sind. Mittels des Gebläses werden die heißen Rauchgase durch das Rohr i in den Sammeltrichter geblasen, um den, gesammelten Flugkoks durch eine oder mehrere vorzugsweise flache Düsen na in den Feuerraum c mitzureißen.Through a pipe, each funnel is connected to the pressure side of a blower k leading line i connected to its. A suction pipe x is connected to the suction side. This ends in the rear part of the boiler pass, but in any case there where hot, There are already flue gases freed from the flying coke. By means of the fan the hot flue gases are blown through the pipe i into the collecting funnel to the collected flycoke through one or more preferably flat nozzles na in to entrain the combustion chamber c.
