The idea to automate coke oven machines as far as possible and to operate coke oven machines without any operator on board has been in discussion for about 30 years because charging, pushing, quenching and unloading of coke is a continuously repeating process which could obviously be done in an automatic mode; however, presently it lacks the necessary electric and control equipment as well as essential mechanical equipment such as leveller door opener; door and frame cleaning were still to be operated manually by operators. Even though advanced electric and electronic equipment which allowed for a manless control of coke oven machines were on the market by the middle of the eighties no great effort was made to run coke oven machines without operators because investment costs for the equipment and costs for maintenance still exceeded the labor costs. But complete functional procedures on the machines will be automated regarding mechanical and process control. The chosen automation configuration with the hardware components specifically selected for severe coke plant conditions as well as the operational experience and know-how obtained meanwhile shows that it is indeed feasible to operate coke oven machines in manless mode, and that the targets set by automation can be reached without any major difficulties so that the higher cost of capital investment involved thereby in fact will pay for itself later-on.
