Method for renewing the brickwork of coke ovens

Brickwork near the outer ends of horizontal coke ovens which forms vertical heating flues in heating walls is renewed by a method wherein the oven chambers at opposite sides of the heating wall are partitioned by vertical walls. These vertical walls are located at a point inwardly in the oven chambers so that a vertical cut can be made through the oven wall of the innermost heating flue to be repaired. The brickwork in front of the vertical cut is then pulled down. New parts for the oven wall are connected to existing parts by oven bricks which have a lug that is arranged when installed so that the lug extends along the heating flue side to engage over existing oven bricks.

Method of renewing the brickwork of coke ovens

A METHOD OF RENEWING THE BRICKWORK OF COKE OVENS Abstract of the Disclosure The invention relates to a method of partly re-newing the brickwork of the vertical heating flues of hori-zontal coke ovens. In heating flues near the oven ends of horizontal coke ovens, the brickwork suffers much more severe wear than the central part of the heating walls. In some cases, therefore, repairs are made only to the brickwork of the heating walls near the oven ends, up to the second, third or fourth heating flue. During rebuilding, the heating flues towards the center are left at a higher temperature and the internal parts of the oven chambers are partitioned off by vertical walls. In the method according to the invention, a vertical cut is made through the oven wall of the innermost heating flue to be repaired, and the brickwork in front is pulled down. The new parts of the oven wall are connected to the existing parts by oven bricks, which have a lug on the heating-flue side which engages over the existing oven bricks.
