CALCINED PETROLEM COKE

As the industrial sector places increasing emphasis on energy efficiency and green sustainability, the efficient recovery and reuse of high-temperature waste heat has become a key pathway to energy conservation and carbon reduction. Developed by Zhongtan Energy (Beijing) Co., Ltd., the High-Temperature Steam Thermal Energy Recovery and Utilization System is designed to precisely capture and convert the large amounts of high-temperature steam waste heat generated during production in industries such as coking, chemical processing, and power generation. The system builds a high-efficiency, controllable thermal energy recovery platform by integrating high-temperature heat exchange, waste heat storage, intelligent scheduling, and multi-stage energy utilization technologies, enabling deep recovery and cascade use of high-temperature steam heat.
The system uses high-temperature-resistant alloys and an innovative fin structure to deliver higher heat exchange efficiency and stability under extreme thermal conditions. Through multi-pressure steam parallel utilization and graded energy supply technology, it ensures full conversion of heat for applications such as power generation and process heating. An AI-driven prediction and load-adjustment algorithm dynamically optimizes recovery rates based on real-time load and demand. Its highly modular and scalable design allows adaptation to diverse industrial scenarios, supporting rapid deployment and customized integration.
With a thermal energy recovery rate exceeding 70%, the system can help users achieve annual energy cost savings of 20%–35%. For a medium-scale installation, it can reduce carbon emissions by approximately 20,000 tonnes per year, providing measurable support for corporate green transformation. The optimized thermal management design reduces high-temperature aging and equipment failure risks, enhancing production line stability. It also supports enterprises in obtaining energy-saving and environmental certifications, strengthening their position in government evaluations, corporate social responsibility ratings, and green financing opportunities.
This project moves beyond the traditional “point-to-point” heat recovery approach, achieving for the first time a systematic, cascade recovery of industrial-scale high-temperature steam. It establishes an original technical architecture in equipment selection, control logic, and operating modes, filling a technological gap in China’s distributed high-temperature thermal energy recovery and reuse solutions.
