“The \"Clean and Efficient Conversion Technology for Anthracite in Spacecraft Furnaces\" was evaluated as a scientific and technological achievement by the Petrochemical Federation. Author/Source: Modern Coal Chemical Engineering; Date: 2020-09-03; Clicks: 6. Changzheng Chemical Engineering Co., Ltd. developed this clean and efficient conversion technology for anthracite, which was applied in the 1 million tons per year methanol production facility as part of the Phase I of the Huayu High-Sulfur Coal Clean Utilization, Integrated Chemical and Thermal Power Demonstration Project. This gasification unit uses high-sulfur anthracite from the Jincheng area as raw material, with 1,500 tons of coal being fed into it per day. In July 2018, the gasification unit was put into operation for trial runs, and in August 2018 the entire production process was operational, enabling the production of qualified methanol products. The project has been operating stably for 2 years, achieving long-term stable operation of the gasification unit. On August 27, 2020, the \"Appraisal Meeting on Scientific and Technological Achievements in Clean and Efficient Conversion Technology of Smokeless Coal Ash using Aerospace Furnaces,\" organized by the China Petroleum and Chemical Industry Federation, was held at the Aerospace Engineering Company. The appraisal committee for this occasion was composed of eight renowned experts in the field of energy and chemicals, including Gu Zongqin, President of the China Nitrogen Fertilizer Industry Association and Secretary of the Party Committee of the Petroleum and Chemical Industry Planning Institute, and Sun Baoci, Deputy Director of Sinopec’s Gasification Center. Li Yongwu, president of the third council of the China Petroleum and Chemical Industry Federation, attended this appraisal meeting. Jiang Congbin, General Manager of the Aerospace Engineering Company, Niu Hongkuan, Chairman and General Manager of Jinmei Huayu Company, and other relevant leaders and staff attended this appraisal meeting for scientific and technological achievements. The meeting was chaired by Wang Xiujiang, deputy director of the Science and Technology Department of the China Petroleum and Chemical Industry Federation. The appraisal committee believes that the clean and efficient conversion technology for smokeless bituminous coal using space furnaces possesses independent intellectual property rights, and it enables the safe, clean, and efficient conversion of smokeless bituminous coal; this technology is at the international leading level in the field of smokeless bituminous coal gasification. From August 13 to 16, 2020, the China Petroleum and Chemical Industry Federation organized an on-site evaluation team to conduct a 72-hour continuous operation test on the gasification unit of the million-ton/year methanol production facility in Phase I of Jinnan Coal Group’s Huayu High-Sulfur Coal Clean Utilization, Integrated Chemical, Power, and Heat Generation demonstration project. The gasification unit of this project uses only anthracite as raw material and pure oxygen as a gasifying agent, employing a pressurized gasification with dry coal powder and water-cooled walls along with a quenching process. Based on the reaction characteristics and ash properties of Jincheng anthracite, a Φ3800/3800 type gasifier and burner suitable for anthracite were developed, and new fluxes were researched and created to effectively lower the ash melting point of the coal fed into the furnace and improve the viscosity-temperature properties of the slag. The system offers a wide operating range (50%-110%), enabling safe, stable, long-term, full-load, and high-quality operation of anthracite with high ash content (≥20%) and high ash melting point (>1500°C). The preparation of pulverized coal from grindable index coal (HGI=35) was achieved, and the reuse of fine ash enabled resource utilization. The assessment results show that the effective gas (CO+H2) production per furnace in the gasification unit is ≥96159 Nm3/h, compared to the oxygen consumption
