摘要:
Dosed proportioning and cutoff of combustion air into the primary heating space of a horizontal coke oven is provided by apertures in the ceiling of the coke oven chamber, the apertures covered with a withdrawable cover device which controls the amount of air admitted, manually or in an automatic mode. By way of this device, ventilation of a coke oven chamber with primary air can be so controlled that primary air is introduced in an exactly dosed manner and, depending on its place of installation, exactly distributed into the primary heating space of a coke oven chamber.
摘要:
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.
