Description
Wirbel- oder Zyklonfeuerung Die Erfindung bezieht sich auf eine Wirbel- oder Zyklonfeuerung für die Verfeuerung stark .asche-und/oder sandhaltiger Brennstoffein einer mit Kühlrohren ausgekleideten Brennkammer runden oder stark abgerundeten Querschnittes, tangentialer Einblasung von Brennstaub und Verbrennungsluft sowie Anfall :der Brennstoffrückstände in staubförmigem Zustand.Vortex or cyclone combustion The invention relates to a vortex or cyclone firing for firing fuels containing a lot of ash and / or sand a combustion chamber lined with cooling tubes with a round or strongly rounded cross-section, tangential injection of fuel dust and combustion air as well as accumulation: the fuel residues in a dusty state.
Die bekannten Feuerungen dieser Art haben den Nachteil, daß bei Verfeuerung stark asche- und/oder sandhaltiger Brennstoffe die Kühlrohre in kurzer Zeit von den Asche- oder Sandteilchen, die mit dem Brennstoff in die Kammer eingeblasen werden, durchgeschlissen werden. Es tritt dadurch nicht nur ein ständiger Verschleiß hochwertigen Rohrmaterials, sondern auch eine starke Beeinträchtigung (der Betriebsbereitschaft der Feuerungs- bzw. Kesselanlagen ein.The known furnaces of this type have the disadvantage that when they are burned fuels containing a lot of ash and / or sand remove the cooling pipes in a short time the ash or sand particles that are blown into the chamber with the fuel, be worn through. This not only results in constant high-quality wear Pipe material, but also a strong impairment (the operational readiness the combustion or boiler systems.
Nach der Erfindung werden wesentlich bessere Verhältnisse geschaffen, indem die Kühlrohre der Brennkammer mit einer Panzerung aus einem Material hoher Verschleißfestigkeit versehen werden. Da bei einer derartigen Brennkammerausbildung ohne weiteres eine Steigerung der Einblasegeschwindigkeit des Staub- und Luftgemisches möglich wird, können weitaus größere Asche- bzw. Sandmengen schon in der Brennkammer ausgeschieden werden, wodurch eine längere Haltbarkeit der an die Brennkammer sich anschließenden Nachschaltheizflächen erreicht wird. Besonders günstig wirkt sich hierbei die Verwendung einer als Zyklonstaubabscheider ausgebildeten Brennkammer aus. Der Verschleiß innerhalb der Brennkammer wird von der Panzerung aufgenommen, die aus einfachen und billigen Werkstoffen besteht und leicht wieder ersetzt werden kann.According to the invention, much better conditions are created, by making the cooling tubes of the combustion chamber with an armor made of a material high Wear resistance are provided. As with such a combustion chamber training an increase in the blowing speed of the dust and air mixture without further ado becomes possible, much larger quantities of ash or sand can already be in the combustion chamber are excreted, increasing the shelf life of the combustion chamber itself subsequent Nachschaltheizflächen is achieved. Has a particularly beneficial effect here the use of a combustion chamber designed as a cyclone dust separator the end. The wear inside the combustion chamber is absorbed by the armor, which consists of simple and cheap materials and can easily be replaced can.
Zylindrische oder als Zyklonstaubabscheider ausgebildete Brennkammern, deren Kühlrohre mit einer Schicht aus Chromerz od. dgl. abgedeckt sind, sind zwar bekannt, doch handelt es sich bei diesen Feuerungen um Schmelzfeuerungen, bei denen die Kühlrohrabdeckungdie Aufgabe hat. -die Wärmeaufnahme der Brennkammerrohre zu verringern, um eine Feuerraumtemperatur zu erhalten, -die über dem Schmelzpunkt der Brennstoffasche liegt.Cylindrical combustion chambers or combustion chambers designed as cyclone dust separators, The cooling tubes of which are covered with a layer of chrome ore or the like, are indeed known, but these furnaces are melt furnaces, in which the cooling pipe cover has the task. -the heat absorption of the combustion chamber tubes decrease to maintain a furnace temperature -that is above the melting point the fuel ash lies.
In weiterer Ausbildung der Erfindung wird als Panzerung ein Material guter Wärmeleitfähigkeit verwendet, damit trotz .der Abdeckung eine möglichst große Wärmemenge an die Brennkammerrohre abgeleitet und der Einbau zusätzlicher Heizflächen vermieden wird.In a further embodiment of the invention, a material is used as armor good thermal conductivity is used, so that, despite the cover, the largest possible Amount of heat dissipated to the combustion chamber tubes and the installation of additional heating surfaces is avoided.
Selbstverständlich genügt es, die Panzerung der Brennkammerkühlrohre nur im Bereich der Wirbel-bzw. Abscheidezone vorzusehen.It goes without saying that the armoring of the combustion chamber cooling tubes is sufficient only in the area of the vortex or. Provide a separation zone.
