ABSTRACT OF THE DISCLOSURE A method of operating a coke-oven battery with regenera- tive heat exchange between the gaseous combustion agents, in which method such properties of the gas supplied for heating, for ex- ample, its calorific value, pressure, density and humidity, as affect the quantity of heat evolved in combustion of the gas are measured continuously and a controller minimizes the effect of variations of such properties on oven operation, characterised in that, if a facility for regenerative change-over of the battery is so devised that each regenerative half-period can be broken down into a time when the burners are heating and a time when no gas is being supplied (pause), and if a final control facility is used which causes the change-over device to provide a desired breakdown as between the two times, the controller so acts on the final control facility that the duration of the heating time corresponds, having regard to the variations in heating-gas pro- perties, to a constant quantity of heat supplied to the battery in each regenerative half-period.
