Recently, the kick-off meeting for the 2017 project under the key research and development program “Clean and Efficient Utilization of Coal and New Energy-Saving Technologies” – namely, “Development and Demonstration of Large-Scale Water-Coal Slurry Gasification Technology” – was held in Zoucheng, Shandong. 　　　It is understood that this project is led by Yankuang Group Co., Ltd., with the participation of 15 other organizations, including East China University of Science and Technology, Tsinghua University’s Shanxi Clean Energy Research Institute, Coal Science and Technology Research Institute Co., Ltd., and Shanxi Yangmei Fengxi Quanji Energy Co., Ltd. Through the mastery of key technologies for ultra-large-scale water-coal slurry gasification units, as well as the mechanisms and processes of multiphase turbulence, mixing, and reaction under high-temperature and high-pressure complex jet conditions, and process intensification, this project will establish two demonstration units: a multi-nozzle opposed-type water-coal slurry gasification unit capable of processing 4,000 tons of coal per day per furnace, and an efficient water-coal slurry gasification unit of the waste boiler-cooling type capable of processing 2,000 tons of coal per day per furnace. 　　　Participants said that this project will promote the integration and demonstration of ultra-large-scale gasification systems with independent intellectual property rights, as well as their technical optimization, thereby developing a comprehensive set of technologies for ultra-large-scale water-coal slurry gasification to support the development of China’s modern large-scale coal chemical industry.
