Research Fields

R&D of circulating fluidized bed (CFB) technology and foundational technology of engineering thermophysics, including high efficient clean combustion, pyrolysis and/or gasification conversion, comprehensive energy conservation and emission reduction of coal, derived fuels from coal, and biomass, etc., multi-phase flow and its diagnosis, combustion chemistry and catalytic combustion, quantitative analysis and application of reaction process.

Team Building

There are 48 research staffs, including 11 professors (one "Hundred Talents Program" and one "Thousand Youth Talents Program"), 11 associate professors/senior engineers, 43 graduate students and 3 post-doctor fellows (one foreign post-doctor fellow).

Projects and Major Achievements

Supercritical CFB technology of coal combustion: the annular and polygon furnace types for large-scale CFB boiler were developed, which can keep the uniformity and stable operation in the process of scaling-up. The demonstration project of 350MW CFB boiler which is the first unit with polygon furnace has passed 168-hour continuous operation at full load.

High efficient and low emission combustion technology: the key technology of ultra-low NOx emission with lean oxygen combustion in furnace and post combustion after the cyclones was successfully applied in the reconstruction of 300MW CFB boiler in Inner Mongolia, and the results show that the NOx emission concentration without SCR or SNCR decreases by more than 50%. 100 t/d preheating combustion CFB boiler burning residue carbon was successfully put into use in Hechi, Guangxi Province, and has been operated stably at low load. And the National Key Research and Development Program Clean Combustion Technology of Carbon-based Fuel with Ultra Low Volatility was obtained.

CFB coal gasification technology: the pilot-scale research work on CFB pure oxygen / rich oxygen gasification and the technology Package with the capacity of kiloton level were finished. The project of Industrialization of Coal Gasification Technology of Circulating Fluidized Bed was obtained and the first related demonstration project was constructed and commissioned. The first demonstration project of pressurized CFB gasification in China was constructed and is in the stage of commission.

Experimental measurement of multiphase flow: microwave dynamic imaging measurement of gas-solid flow was realized for the first time. And the onsite test of flow morphological imaging of wet natural gas pipeline entrusted by China National Petroleum Co. Ltd. was finished; Multiple-sized gas-solid EMMS calculation of CFB with complex furnace was finished, which can provide guide for the R&D of supercritical CFB technology.

Combustion chemistry: the rules of low temperature oxidation kinetics of aviation model fuel were obtained and the plasma VOC removal technology at room temperature was successfully realized.

Technology Transfer

More than 10 collaboration projects of new CFB gasification or improved CFB technology development were signed with Enterprises. The technical development fee of 19.96 million Yuan in RMB was awarded.

Datong Institute of Coal Clean Efficient Utilization cooperatively established with Datong Government in Shanxi Provence was settled, which aims to carry out the R&D of coal clean efficient utilization and industrialization of scientific results in order to form a world-leading R&D center and industrial base for coal clean efficient utilization.
