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.
Claims21
A method for proportioning of secondary combustion air into the secondary air sole of coke oven chambers of a coke oven battery or a coke oven bank, comprising:
- feeding secondary combustion air through secondary air apertures in a frontal coke oven chamber wall in the lower area of the coke oven chamber beneath a coke oven chamber door into a secondary air sole and then streaming the air into a secondary heating space located there above;
- and
- partly burning coking gas in the upper area of the coke oven chamber and is and then completely burning the coking gas, with the completely burnt coking gas being conducted through the entire secondary heating space so that the coke cake is additionally heated from the lower side;
- wherein
- the secondary air aperture is covered by a parallelepiped attachment linked via a con-rod to a thrust bar so that the parallelepiped attachment opens or closes the secondary air aperture with its front-end side at each position along the coke oven chamber wall while the thrust bar is moved longitudinally along the frontal coke oven chamber so that the secondary air quantity admitted into the secondary air sole can be proportioned;
- and
- the thrust bar can be traversed via connecting webs through a positioning motor or manually so that the secondary air quantity admitted into the secondary air sole is proportioned as this thrust movement is made.
A device for proportioning the secondary combustion air into the secondary air sole of coke oven chambers of a coke oven battery or a coke oven bank, wherein:
- a plurality of apertures in a frontal coke oven chamber wall beneath a coke oven chamber door are provided for entry of secondary combustion air into a plurality of channels positioned beneath a coking chamber, wherein a partly burnt coking gas is mixed with a secondary combustion air and burnt completely, so that a coke cake is heated from below by the combustion of the partly burnt coking gas;
- a plurality of parallelepiped attachments are provided on the front side of the apertures, the parallelepiped attachments having a cuboid side away from the oven, which on the cuboid side away from the oven are linked to a second smaller cuboid;
- a con-rod or a connecting web through which the second cuboid is linked to a thrust bar is mounted on the upper side of the second smaller cuboid;
- the thrust bar can be traversed through a positioning motor or manually in parallel to the frontal coke oven chamber wall;
- and
- the thrust bar is movable longitudinally along the coke oven chamber wall, and when moved, moves the parallelepiped attachments by the longitudinal movement along the apertures so that these open or close the apertures depending on the position of the parallelepiped attachments.
