At 0:17 a.m. on September 3, 2025, the dry quenching of coke and waste heat power generation project at Inner Mongolia Fangmei Coking Co., Ltd. successfully completed the warm-up, startup, electrical testing, high and low pressure valve tests, overspeed tests, as well as inspections of various protection functions, and was able to generate electricity and connect to the grid on the first attempt. The achievement of this milestone marks a partial success in the full set of startup tests for the unit, laying a solid foundation for unit #2 to begin generating electricity on the grid. The total investment for this project is 591 million yuan. It is an online renovation project, and construction must be organized under the premise of ensuring safe production; there are many concurrent tasks, high safety risks, and the construction is challenging. During this period, the U.S.-based coking company worked closely together with the general contractor, supervision agency, and other project participants, overcoming numerous difficulties to advance the construction efforts; it took a total of 503 days to get the first set of generating units connected to the power grid. The dry quenching of coke project is not only an \"essential option\" for the low-carbon transformation of the coking industry, but also the \"optimal solution\" for achieving a circular economy and high-quality development. The successful grid connection of Unit 1 is of great significance. From the design for recovering the high-temperature waste heat from the dry quenching furnaces to the precise tuning of the steam turbine and generator sets, the American coking company focuses on the \"energy recycling value chain\" to convert the heat energy released during the cooling process of each ton of coke into clean electricity, thereby turning industrial waste heat into a \"quantifiable and operational\" green asset. The successful commissioning of this project will effectively help the company reduce costs and increase efficiency. This not only lowers the company’s production and operating costs as well as boosts its earnings, but it also contributes to strengthening the company’s overall competitive advantages. Once the project is fully operational, it is expected to recover approximately 470,000 tons of low-pressure steam per year, as well as around 160 million kWh of electricity per year, thereby reducing annual carbon emissions by about 170,000 tons.
