The core hub of connecting the coking furnace and the dry quenching furnace in the process of dry quenching, namely, the rotating coking drum was focused on. It expounds in depth the principle and advantages of the forced alignment technology in response to the pain points of low precision, many faults and great safety risks in the traditional alignment method. Combining with the practical case of Hebei Fengmei Coal and Coking 2×140 t/h dry coking project, the implementation key points of the rotating coking drum forced alignment double redundancy device was focused on. Practice has proved that the technology can successfully improve the positioning accuracy from the traditional ±100 mm to within ±10 mm. The root cause of red slag falling and equipment damage was eliminated, and the level of system automation was significantly improved, providing key technical support for the long-term safe and stable operation of the dry quenching system.
