CA 2736577
The invention relates to a device for proportioning of secondary combustion air into the secondary air soles of coke oven chamber ovens, said device being formed by a slide gate or a parallelepiped device or by plates moved by means of a thrust bar, said thrust bar being moved longitudinally in parallel to the coke oven chamber wall so that the plates move away from the secondary air apertures and open or close these. The thrust bar is moved by means of a positioning motor, with the power transmission being effected hydraulically or pneumatically. Via suitable measuring parameters, it is thus possible to optimize secondary heating so that heating is provided evenly from all sides, thus achieving an improvement in coke quality.
Dispositif de dosage d'air de combustion secondaire dans les soles d'air secondaire de fours à chambre à coke, se présentant sous la forme d'un volet coulissant ou d'un dispositif parallélépipédique ou de plaques, déplacés à l'aide d'une tige de poussée. Ladite tige de poussée est déplacée longitudinalement et parallèlement à la paroi de chambre du four à coke, si bien que les plaques s'éloignent des orifices d'air secondaire et ouvrent ou ferment lesdits orifices. La tige de poussée est déplacée à l'aide d'un moteur de commande, la transmission de force se produisant de manière hydraulique ou pneumatique. Des paramètres de mesure appropriés permettent d'optimiser la chauffe secondaire si bien que la chauffe a lieu uniformément de tous les côtés et permet d'obtenir une amélioration de la qualité du coke.
