ABSTRACT:
Regenerative changeover of a coke oven battery is designed for operation according to a method wherein each regenerative half period is broken down into a time when gas is supplied at a constant pressure to the burners in heating flues and a time when no gas is supplied. A final control facility acts on the regenerative changeover facility to enable the regenerative half period to be broken down into these two time periods. A controller is responsive to variations in gas properties, such as the calorific value, density, humidity and temperature, to bring about operation of the final control element so that the heating time and the pause in every regenerative half period have values such that the heat supplied to the battery in each half period remains constant.
