Air metering system for secondary air in coking furnaces as a function of the ratio of cupola temperature to sole temperature

摘要

The invention relates to a device for metering secondary combustion air in the secondary air soles of coking chamber furnaces, wherein said device is formed by a pusher or a block-shaped device or plate displaced by means of a pushrod, wherein said pushrod is moved longitudinally parallel to the coking chamber furnace wall, so that the plates move away from the secondary air openings and open or close said openings. The pushrod is moved by means of a servomotor, wherein the force transmission is done hydraulically or pneumatically. Using suitable measurement parameters, the secondary heating can thus be optimized, so that the heating is even on all sides, thus achieving an improvement in coke quality.
