China Drying Network News The gasification technology of coal-water slurry water cooled Tsinghua Furnace jointly developed by Tsinghua University, Beijing Yingde Qingda Technology Company and Shanxi Yangmei Fengxi Fertilizer Industry (Group) Co., Ltd. was adopted in Beijing on September 3rd. The identification of scientific and technological achievements organized by China Petroleum and Chemical Industry Federation. The appraisal committee headed by Academician Xie Kechang agreed that the overall technology of this achievement is at the leading international level, and it is recommended to speed up the development and application of large-scale technology.

Zhang Guobao, chairman of the National Committee of the Chinese People's Political Consultative Conference and director of the National Energy Commission's expert advisory committee, and Li Yongwu, president of the China Petrochemical Association, attended the results appraisal meeting. Chinese Academy of Engineering academicians Xie Kechang, Ni Weidou, Qi Kefa, Qin Yuyu, Sun Zhengtai, Fang Dejun and other famous experts in the field of coal chemical industry form an expert committee.

The appraisal committee believes that this technology, through the interdisciplinary integration of thermal engineering and chemical engineering, has established the world's first commercial scale (600 tons of coal per day) coal-water slurry water-wall gasifier. The new gasifier has the same specific oxygen consumption, specific coal consumption, effective gas composition and cold gas efficiency as the same refractory brick gasifier under the same coal type and the same operating conditions, and the gasification equipment has been operating for 279 days in total. The 72-hour continuous operation assessment shows that the device operates smoothly, the automation level is high, the safety and reliability are good, the control performance is good, the investment and operation cost are low, and the adaptability of the coal is good; all the devices adopt China's independent technology and domestic equipment, and the localization rate It reaches 100%. The assessment data has reached the design index, in which the effective composition of syngas reaches 78.46% and the carbon conversion rate reaches 97.6%. It is recommended to accelerate the development of large-scale technology and promote its application.

Zhang Guobao pointed out that the development of coal chemical industry in China is relatively fast, and it is the largest coal gasification market in the world. The promotion of advanced coal gasification technology can not only contribute to China's energy substitution strategy, but also can go out and account for a significant proportion of coal resources. National output technology. He called for all sectors of the community to work together to support independent coal chemical technology, and all production, research, and research institutions are more active in promoting localization.

Li Yongwu expressed the hope that the three parties involved in the production, research, and development of the project will continue to work together to further optimize the process and advance to the scale of processing 2,000 tons of coal per day, completing large-scale demonstration projects as soon as possible.
