A metod is described for preventing the overcharging of coal into a coke oven system in which preheated coal is transported from a storage container to the coke ovens by means of a substantially enclosed continuous conveyor system filled with inert gas. A portion of inert gas within the enclosed conveyor system is carried along with the coal into the coke oven itself. During filling of the oven, this inert gas is carried up and out of the oven standpipes. When the oven becomes filled, however, the standpipe escape route becomes blocked resulting in a rapid pressure buildup within the system. This rapid pressure build-up is utilized to generate a signal to stop further filling of the oven. The instant method may be employed as a primary regulating system, but is more preferably employed as a back-up to conventional sensor probes used for regulating the level of coal.
