The heat storage chamber of the coke oven is positioned at the lower part of the coke oven body and consists of a small flue, grate bricks (grate plates), lattice bricks and an upper space from bottom to top, and one end or two ends of the small flue are connected with corresponding waste gas trays and used for introducing air or lean gas and leading out waste gas. In order to adjust the uniformity of the air flow distribution of the regenerator, grate bricks with different resistances (the grate bricks with different pore diameters are prefabricated or the area of an air flow channel is adjusted by utilizing adjusting bricks) are required to be configured along the length direction of the regenerator, or a metal adjusting plate is additionally arranged above the small flue; for the pull-type grate plate, the resistance at the corresponding position is adjusted by replacing the grate plate with different holes, so that the distribution of gas in the length direction of the regenerator is more reasonable.
When the grate plate is used for adjustment, metal elastic sealing rollers are arranged at the joints among the grate plates and are used for contacting with the bottom of the partition wall of the regenerator so as to achieve the purpose of cell adjustment of the regenerator. But because the adjusting stroke of the grate plate is longer, the maximum operating stroke can reach half the body position of the coke oven in the length direction even if the coke oven is operated from two sides; each time of adjustment, the metal elastic sealing roller can collide with the supporting brick at the bottom of the partition wall of the regenerator, and particularly the metal elastic sealing roller at the inner side almost collides with the supporting brick in the whole process; as the adjustment process continues, wear of the support bricks inevitably results.
