【Ten Years of Rapid Development in Chemical Engineering Equipment】2300-2025: Saiding smokeless lump coal pressurized moving bed gasification technology (JM-S furnace)
Thread Content
Let’s give praise and encouragement 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】A continuously updated summary post is available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On March 24-25, at the “2025 Science and Technology Conference for the Construction Industry” held in Chengdu by the China Construction Enterprise Management Association, SaiDing Engineering Co., Ltd.’s “Smokeless Lump Coal Pressurized Moving Bed Gasification Technology (JM-S Furnace)” was awarded the third prize for scientific and technological progress in the construction industry for the year 2024. The smokeless lump coal pressurized moving bed gasification technology (JM-S furnace) addresses various issues associated with coal pulverization pressurized gasification technology, such as low steam utilization efficiency and uneven gasification temperature distribution, through comprehensive optimization and systematic upgrading of the furnace structure and process flow. It results in a complete set of specialized equipment and gasification technology processes suitable for use with smokeless, low-quality lump coal across the country, offering advantages such as low renovation costs, reduced coal consumption, high gas production, and low operating and maintenance expenses. Under full-load operation, the cost of synthetic ammonia can be reduced by about 200 yuan per ton, resulting in a reduction of production costs of 30 million yuan per furnace per year. “The “JM-S Furnace Demonstration Project” is used by Henan Jinkong Tianqing Coal Chemical Company. It has been in operation for four years now, running stably and bringing good economic benefits to the enterprise. In contrast, the Luchi furnace suffers from drawbacks during long-term operation, such as high gasification temperature, high steam consumption, severe grate wear, and short service life of the upper and lower valves in the ash lock.
In May 2020, the \"JM-H\" furnace, jointly developed by Shanxi Jinmei Group and Xi’an No. 6 Research Institute of AVIC, completed a 168-hour industrial test at Jinfeng Wenxi Chemical Company in Yuncheng City, successfully overcoming the global challenge of gasifying slag from high-ash-melting-point anthracite coal. As the largest coal chemical enterprise group in China, Jinmei Group thoroughly implements the new development concepts, seizes the strategic opportunities presented by the energy revolution, and earnestly follows the overall requirements and guidelines set forth by the Shanxi Provincial Party Committee. It actively promotes the transformation of the traditional coal chemical industry toward a more advanced, differentiated, market-oriented, and environmentally friendly model. The group came up with the innovative idea of \"selling coal along with the furnaces, and selling gas along with the furnaces.\" In collaboration with Xi’an Sixth Research Institute, it developed the \"Jinhang Furnace.\" After two years of effort and an investment of 286 million yuan, it succeeded in establishing the only platform in China for the development of pressurized slag gasification technology using lump coal. “The \"Jinhang Furnace\" industrial test facility consists of 15 subsystems. Through preliminary research, the key technology of slag gasification for coal types with high ash fusion points has been mastered, and long-term operation tests are currently underway. Compared with traditional fixed-bed batch gas generation furnaces, this project offers a range of advantages, including low renovation costs, reduced coal consumption, higher gas production volume, higher level of automation, zero emissions, and lower operation and maintenance costs. The carbon conversion rate is greater than 99.5%, the carbon content in the slag is less than 0.5%, and the steam decomposition rate is above 95%. The resulting slag is in a harmless glassy state, and the by-products produced can be recycled, enabling full utilization of the coal material. This approach provides an efficient, clean, and economical new method for the gasification of high ash-melting-point anthracite coal, both for the province as a whole and across the country.
Give a thumbs up and encouragement to the achievements of China’s chemical technology and equipment industry!
Kudos to the development of chemical equipment technology!
