Abstract According to the structure and process characteristics of regenerator in coking oven, a three dimension mathematical model was built to describe the flowing process in the flue and ramp area, the model was numerical solved and the law of the gas flow in regenerator was revealed, the pressure, flow distribution of the oulet in the flue and ramp area were obtained. The results show that the relative pressure along the length direction of the coking oven increases gradually; when the structure size is the same, the outlet flow of the grate brick which is nearer to the center of regenerator was greater. As the symmetry of the structure, law of the gas flow at the coke side in regenerator is the same as the machine side; it is good for the temperature uniformity along the length direction to adjust the size of grate brick legitimately. From machine to coke side, the gas flow at the outlet of the ramp area is increasing gradually except the furnace end; they are larger than others because of the greater heat dissipation.
