Recently, the \"Service Project on Assessing the Adaptability of Aerospace Furnace Gasification Technology to the Coal from Yihua in Xinjiang\", carried out jointly by the First Academy of China Aerospace Science and Technology Corporation and Xinjiang Yihua Mining Co., Ltd., successfully passed the expert evaluation organized by the China Nitrogen Fertilizer Industry Association. The project successfully overcame the technical challenges associated with the high alkali metal and high ash fusion point characteristics of the coal from Zhundong, Xinjiang, and enabled the industrial use of this coal in pressurized fluidized bed gasification units. It provided a replicable \"spaceflight-based solution\" for the clean and efficient utilization of coal in regions with similar coal properties. The Jundong region in Xinjiang is rich in coal resources, but due to characteristics such as high levels of alkali metals and a high ash fusion point in the coal quality, its use in fluidized bed gasification technology has faced challenges for a long time. Relying on its independently developed pressurized gasification technology for coal in space engineering, and through continuous research efforts and process innovations, it has successfully developed ash regulation techniques suitable for the coal in Zhundong, Xinjiang. In the “Service Project for Evaluating the Adaptability of Space Furnace Gasification Technology to Yihua’s Coal from Xinjiang”, the project team conducted tests in multiple stages, burning over 10,000 tons of Yihua coal from Zhundong in total, and completed system verification for burning at 50%, 75%, and up to 100% purity. During 7 consecutive days of stable operation, the space furnace gasification unit demonstrated excellent performance in terms of high gasification efficiency, stable operation, and compliance with environmental standards, with its key indicators reaching advanced levels in the industry. The appraisal experts unanimously agreed that the trial operation technical plan for the coal powder gasification industry of Yihua in Zhundong, Xinjiang is reasonable, with detailed and reliable data as well as excellent operational parameters; it fully meets the technical requirements for large-scale industrial application. This technological breakthrough not only further expands the range of feedstocks that can be used in space-based coal gasification technology, but also provides a reliable approach for the clean and efficient conversion of similar coal-quality resources across the country; it holds great significance for the sustainable development of the coal chemical industry. Going forward, aerospace engineering will continue to advance process optimization and technological innovation, accelerating the adoption of these achievements in Xinjiang as well as in similar coal-quality regions across the country. In this way, it will contribute to the clean and efficient conversion of coal and support the green and low-carbon development of the energy and chemical industries.
