Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】Regular updates and summaries are available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** The 15 million tons per year coal upgrading project carried out by Xinjiang HuiNeng uses boilers equipped with high-temperature lignite solid particle waste heat recovery converters. Recently, good news came from the construction site of this project: the 4 boilers equipped with such converters passed the hydraulic testing successfully, despite the harsh weather conditions, and all their parameters met the design requirements, achieving the goals of “zero leaks and zero defects”. This is not only a breakthrough in engineering aspects but also a major innovation in the field of coal chemical industry, representing direct recovery technology for the waste heat generated by solid particles. In the Gobi climate zone, where temperatures drop below minus 30 degrees Celsius and there are large differences between day and night temperatures, this set of core equipment with independent intellectual property rights has solved the problem of difficulty in fully utilizing the waste heat from high-temperature solid materials in this industry. Unlike traditional industrial waste heat recovery systems that rely on gases as heat transfer media, the transducers installed this time utilize the cutting-edge \"direct recovery technology for waste heat from solid materials,\" enabling a fundamental transformation in the heat exchange mechanism. In the Xinjiang HuiNeng project, the upgraded coal is produced in the form of high-temperature solid particles from a pyrolysis unit. This equipment does not use any intermediate media; instead, the high-temperature coal particles rely on gravity to form a moving bed that comes into direct heat exchange with the tubes of the boiler’s heating surfaces, thereby minimizing heat losses. The key breakthrough is first, an improvement in energy efficiency and stable output. By eliminating intermediate media, heat loss and power consumption are reduced; the waste heat recovery rate exceeds 80%, and the self-power consumption is about 20% lower than that of traditional technologies ； By coordinating with flue gas circulation, steam is raised to high temperature and pressure, ensuring stable and safe output while improving system efficiency ； Second, the medium is clean, environmentally friendly, and safe. The closed-loop heat exchange system prevents the accumulation of impurities, ensuring that the quality of steam meets the requirements of the process. It also avoids the risks of secondary oxidation and spontaneous combustion of the coal used for quality improvement, thereby safeguarding the safety of both the products and the production process. Once the system is put into operation, it converts high-temperature waste heat into high-quality steam to feed back into production, thereby saving water resources and reducing overall energy consumption. For the Gobi region, this approach holds both economic benefits and ecological significance as a model for such practices. From extreme cold to completion, the construction team demonstrated the concept of \"new quality productivity\" through hard work. The success of this domestically developed equipment will surely provide a \"Chinese solution\" for the clean utilization of coal worldwide.
