The process of calcining petroleum cokevia vertical shaft kiln is complex and requires high energy consumption, with cross coupling operation of material flow and energy flow. By establishing mathematical and physical models for the coordinated operation of material flow and energy flow, the energy consumption process of the system can be effectively analyzed and the irrationality of its energy consumption can be optimized. Through simulation case studies, this paper analyzes the energy consumption characteristics and existing problems of the petroleum coke calcination and waste heat utilization process on vertical shaft kiln, and proposes an optimized new process that improves the ordering degree of subsystems and the coordination degree of the entire system. The summer power generation reaches 12.85MW·h, winter steam production is 59.77t/h, and the synergy degrees of the original system in summer and winter are increased to 0.744 and 0.696, respectively. It also points out the direction and consolidates the theoretical foundation for the future energy conservation and consumption reduction development of carbon plants.
