Abstract
A device for proportioning of secondary combustion air into the secondary air soles of coke oven chamber ovens is shown. The device is formed by a slide gate or a parallelepiped device or by plates moved by means of a thrust bar, the 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.
