Description
Flammrohreinbauten. Es ist bekannt, die Flammrohre von Dampfkesseln mit einem Futter aus feuerfestem Stoff zu versehen, um die Flugaschenbildung zu vermindern. Die feuerfesten Einbauten werden beim Betrieb der Feuerung glühend und bewirken eine Nachverbrennung der Flugasche, sobald diese mit ihnen in Berührung kommt.Flame pipe internals. It is well known, the flame tubes of steam boilers to be provided with a lining made of fireproof material to prevent the build-up of fly ash Reduce. The refractory fixtures are glowing and glowing when the furnace is in operation cause the fly ash to burn afterwards as soon as it comes into contact with it comes.
Bisher bestehen die Einbauten aus zylindrischen oder kegelförmigen Körpern, die entweder als Futter unmittelbar auf der Wandung des Flammrohres angeordnet oder aber freistehend hintereinander eingebaut sind. Diese Vorrichtungen erfüllen ihren Zweck nur unvollkommen, weil sie die durch <lie Verbrennungsgase unmittelbar bestrichene Heizfläche des Flammrohres vermindern und anderseits nur ein Teil der mitgeführten Flugasche mit ihnen in Berührung kommt. Nach der Erfindung werden diese Einbauten wesentlich dadurch verbessert, daß sie trichterförmig ausgebildet sind. Dadurch wird der die Flugasche und andere brennbare Teilchen enthaltende Verbrennungsgasstrom wieclerholt in gute Berührung mit den glühenden Einsatzkörpern gebracht, weil deren Wandung schräg in das Flammrohr hineinragt und weil durch diese trichterförmigen Einbauten eine Mischung des Verbrennungsgasstromes bewirkt wird. Es kommen infolgedessen alle noch brennbaren Flugaschenteile einmal mit einer Stelle der glühenden Einbauten in Berührung, so daß vor dem Verlassen -des Flammrohres eine vollkommene Verbrennung stattgefunden hat.So far, the internals have been cylindrical or conical Bodies that are either arranged as a lining directly on the wall of the flame tube or they are installed free-standing one behind the other. These devices meet Their purpose is only imperfect, because they let the combustion gases through directly Reduce coated heating surface of the flame tube and on the other hand only part of the carried fly ash comes into contact with them. According to the invention, these Internals significantly improved in that they are funnel-shaped. This causes the flue gas flow containing the fly ash and other combustible particles wieclerholt brought into good contact with the glowing insert bodies because of their Wall protrudes obliquely into the flame tube and because of this funnel-shaped Internals a mixture of the combustion gas stream is effected. It comes as a result all still flammable fly ash parts once with a spot of the glowing fixtures in contact, so that a complete combustion before leaving the flame tube has taken place.
In der Zeichnung ist eine Ausführungsform der Vorrichtung dargestellt. Es zeigen: Abb. z einen Längsschnitt, Abb. 2 einen Querschnitt.In the drawing, an embodiment of the device is shown. They show: Fig. Z a longitudinal section, Fig. 2 a cross section.
In das Flammrohr a sind die trichterförmigen Körper b, c, d aus feuerfestem Stoff so eingebaut, daß sie das Flammrohr nur mit ihrer Abstützung e berühren, im übrigen aber das Bespülen der Flammrohrwände durch die Verbrennungsgase gestatten. Beim Durchströmen durch das Flammrohr kommen infolge der trichterförmigen Anordnung der Einbaukörper alle in den Verbrennungsgasen nc;ch enthaltenen brennbaren Teilchen mit den glühenden Körpern in Berührung, so daß eine vollkommene Nachverbrennung stattfindet. Man könnte gegebenenfalls die Einlauten auch umgekehrt, also mit der engen Öffnung nach dem Rost hin gerichtet einsetzen.In the flame tube a, the funnel-shaped bodies b, c, d made of refractory material are installed in such a way that they only touch the flame tube with their support e, but otherwise allow the flame tube walls to be flushed with the combustion gases. When flowing through the flame tube, due to the funnel-shaped arrangement of the built-in bodies, all the combustible particles contained in the combustion gases come into contact with the glowing bodies, so that complete afterburning takes place. If necessary, the entrances could also be used the other way around, i.e. with the narrow opening directed towards the grate.
