Embodiment Construction

[0041] figure 1 Shown are cuboid-shaped attachments ( 1 ) or plates according to the invention which close the secondary air openings ( 2 ) of the coke oven chamber ( 3 ). The cuboid-shaped attachment (1) is connected via connecting bars (4) to a push rod (5), which is displaceable in the longitudinal direction relative to the front coke oven chamber wall (6). The push rod is held in the corresponding position by suitable fastening means (7). The secondary air openings lead into secondary heating chambers (8) in the furnace in which complete combustion of the partially burnt coking gases takes place and which are shown shaded here because They have no openings in the front coke oven chamber wall ( 6 ). The push rod (5) is driven in this figure by a servo motor (9) mounted on one end of the push rod (5). In the embodiment shown here, the servomotor drives a hydraulic or pneumatic device by means of which the drive piston ( 9 a ) is moved in the pressure cylinder ( 9 b ). Th...

Abstract

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.

Description

technical field [0001] The invention relates to a device for controlling the amount of secondary combustion air in a coking chamber furnace of a coke oven battery of the "heat recovery" or "non-recovery" type, wherein the device is controlled by means of cuboid attachments or plates To regulate the air volume, the attachment or plate is driven by a servomotor, so that the device can be adjusted, for example, by a control mechanism in relation to the measured values ​​in the coking chamber furnace. In this way, the heating of the coke cake of the coke oven battery can be substantially uniform and improved by means of the secondary heating chamber located below the coke cake. The quantity of secondary air can be supplied by the device according to the invention in several quantity steps as required. The quantity of nitrogen oxides formed can be significantly reduced by introducing the secondary air in several stages. The invention also relates to a method for metering secondar...
