Development and technical progress in large-scale circulating fluidized bed boiler in China

Zhong HUANG, Lei DENG, Defu CHE

Frontiers in Energy 2020, Volume 14, Issue 4,   Pages 699-714 doi: 10.1007/s11708-020-0666-3

Abstract: Circulating fluidized bed (CFB) boilers has realized the clean and efficient utilization of inferior coal like gangue and coal slime, high sulfur coal, anthracite, petroleum coke, oil shale and other resources. As a country with the largest amount of CFB boilers and the largest installed capacity in the world, China has 440 100–600 MW CFB boilers with a total capacity of 82.29 GW , including 227 units of 135 MW , 95 units of 300 MW , and 24 supercritical units. The statistics of typical 100–300 MW CFB boilers showed that the average number of unplanned shut-down was only 0.37 times per year, among which the 135 MW was 0.26 times per year and 300 MW was 0.46 times per year. The auxiliary power ratio of some 300 MW CFB boilers based on flow-pattern reconstruction can be reduced to about 4%, which is closed to the same level of pulverized coal (PC) boilers. This paper summarizes the development process and application status of China’s large-scale CFB boilers, analyzes the characteristics and technical performance of the iconic units, and introduces solutions to the problems such as water wall wear and bottom ash cooling.

Abstract:

China is rich in hydropower resources, and hydropower technology development is the first choice to increase the supply of renewable energy, optimize the energy structure, and alleviate environmental problems. This paper focuses on rich microhead resources in China and presents the demand and application characteristics of microhead resources such as rivers, canals, reservoirs, power plant tailings, piped water supply, municipal wastewater, and marine energy. The paper summarizes two types of microhead hydro-turbines suitable for open and closed watersheds, which provide a basis for the design method of microhead hydro-turbines and the study of their flow characteristics and mechanism. This paper introduces the research trend of microhead resource evaluation and hydropower turbines. In addition, some suggestions for future research are put forward.
