Description
Verfahren zur Nutzbarmachung des im Sammelräumen der Hauchgäszüge aufgefangenen Flugkokses durch Rückführung in den Feuerraum Bei Feuerungen ist es bereits bekannt, Rauchgase in den Feuerraum zurückzuführen.. Ferner ist es'vorgeschlagen worden,.Flugköks und andere brennbare . Rückstände aus _ einem Sammeltrichter durch einen Druckluftstrom in die Feuerkammer zurückzuführen.Process for utilizing the gas in the collecting areas of the Hauchgäszüge caught flycoke by returning it to the combustion chamber already known to return flue gases to the combustion chamber. It is also proposed been, .Flugköks and other flammable. Residues from _ a collecting funnel through return a stream of compressed air to the firebox.
Der Erfindung gemäß werden zur Rückführung und damit zur Nutzbarmachung des Flugkökses. 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 Zem'Einblasen mit kalter Luft abgekühlt. Sie sind daher im Feuerraum schneller brennfahi und elan en adurch zur vollkonvn6nenVerbrennung, ehe sie wieder -mit Sieäeröhren=es Kessels in Berührung kommen: Ferner wird beim Einblasen mit Rauchgasen ein zu großer Luftüberscbuß 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, the return and thus the utilization of the Flugköks are used. Instead of the compressed air flow, hot flue gases are used as the exclusive propellant, which are sucked in from the flues by means of a fan and fed to the collecting spaces through a blower nozzle. This has two advantages: The hot Flugkoksteile which come into the hoppers of the boiler plant for separation are, this is not cooled as Zem'Einblasen with cold air. They are therefore more quickly combustible in the furnace and elan to fully convince combustion before they come into contact again with the boiler: Furthermore, when blowing in flue gases, an excessive excess of air in the furnace is avoided. You are not tied to a certain minimum amount of the conveying means for the fly coke, and you can blow in such a large amount of flue gases that the flue gas flow simultaneously causes a swirling of the flue gas in the furnace, 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, beispielsvieise 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 that arranged 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 provided in the 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 k 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 z in den Sammeltrichter geblasen, um den gesammelten Flugkoks durch eine oder. mehrere vorzugsweise flache Düsen m in den Feuerraum c mitzureißen.Each funnel is connected to the pressure side through a tube k. one Fan k leading `line i connected, on the suction side of which there is a suction pipe x connects. This ends in the rear part of the boiler train, but anyway where there are hot flue gases that have already been freed from the flying coke. Means of the blower, the hot flue gases are fed through the pipe z into the collecting funnel blown to the collected flight coke through an or. several preferably flat ones Drag nozzles m into the combustion chamber c.
