Abstract: A strain-free stationary furnace door actuator for a coke furnace battery of the “non-recovery” or “heat-recovery” type, by way of which vertical opening of the coke furnace chamber doors is possible without the use of a coke furnace operating machine, wherein the deviations of the tension elements of the furnace door actuator from the intended arrangements, which result from strain of the transmitting devices, and undesired increases in tension force, which result from differences in the adhesion forces of the coke furnace chamber doors during closure, are avoided by the use of low-strain transmitting devices and tension elements. A method for the strain-free, stationary actuation of the door of a coke furnace battery of the “heat-recovery” type is also disclosed. The method uses rigid tension elements and low-strain transmitting devices for automatically opening and closing coke furnace chamber doors.
