The World's First 660 MW Ultra-Supercritical CFB Power Project

In a groundbreaking development for the energy sector, Harbin Electric Corporation has successfully commenced operations of the world's first 660 MW high-efficiency ultra-supercritical circulating fluidized bed (CFB) power generation unit, which is situated in Binchang, China. This remarkable initiative recently completed a 168-hour full-load trial operation, establishing a new international standard in power generation technology.

The Binchang Project is a significant demonstration initiative supported by the Ministry of Science and Technology along with the National Energy Administration. It serves as a key player in the coal industry focusing on ecological restoration within the Yellow River Basin. The project adeptly combines the utilization of solid waste and mine water with mine geological environment rehabilitation and land reclamation efforts.

The project is planned to be conducted in two phases. Upon full operation of the first phase, it is projected to annually convert around 2 million tons of low-calorific value coal and inferior fuels, including coal slime and gangue. Alongside this, it will employ 2 million tons of mine water and supply approximately 6 million GJ of heat, catering to the heating needs of Binzhou City and satisfying local industrial steam demands. This comprehensive approach aims to stabilize the regional power grid, address local electricity shortages, and promote sustained socio-economic growth in the area.

The engineering marvel incorporates three core components designed by Harbin Electric Corporation: the boiler, turbine, and generator. Among these, the standout feature is the CFB boiler developed by Harbin Boiler Company, known for its ultra-low emissions, ultra-high parameters, and minimized energy consumption. This domestically produced boiler boasts independent intellectual property rights, solidifying its status as a leader in CFB boiler technology.

Another highlight is the ultra-supercritical indirect air-cooled reverse-flow turbine, engineered by Harbin Turbine Company. This turbine delivers remarkable thermal performance and flow efficiency, qualifying it as a 660 MW-class turbine characterized by a once-through reheat, single-axis, three-cylinder, two-exhaust design.

Joining these innovations is the high-efficiency generator crafted by Harbin Electric Machinery Company. This generator is noteworthy for its high output, exceptional efficiency, reduced temperature rise, and minimal vibration, adeptly programmed for wide-load operation amidst challenging conditions. Its design enables outstanding performance in scenarios involving deep peak shaving, leading phase operation, and negative-sequence functionalities.

The ultra-supercritical CFB power generation technology epitomizes a remarkable achievement within China's 13th Five-Year Plan. It heralds advancements in high-parameter, large-capacity, and energy-efficient CFB technologies, aligning with the nation's objectives for a new energy development era. This initiative echoes Harbin Electric Corporation's commitment to nurturing competitive advantages via sustainable, low-carbon energy technologies, ultimately driving the emergence of new productive forces to meet dynamic energy landscape challenges.

Leveraging resources from China's 13th Five-Year Plan, Harbin Electric Corporation has established partnerships with leading universities including Tsinghua, Xi'an Jiaotong, Zhejiang, and Chongqing.

By integrating cutting-edge technology with practical engineering methodologies, the corporation has effectively overcome major obstacles to create ultra-high-parameter CFB boiler equipment that scales up to an impressive 660 MW capacity. The boiler reaches a main steam pressure of 29.3 MPa, which is equivalent to the pressure four adults would exert while standing on a nail-sized section of pipe.

With main steam temperatures measured at 605°C and reheat steam temperatures at 623°C, the unit sets new international benchmarks for CFB boiler parameters. Achieving an impressive 95% desulfurization efficiency, this boiler minimizes emissions for widespread CFB applications.

Harbin Electric Corporation's dedication to quality has propelled the Binchang project from its initial proposal evaluation to achieving national demonstration status under the 13th Five-Year Plan. The project has seen success at every stage, from construction and hydrostatic testing to grid connection and commissioning. The culmination of this journey results in a world-class power generation facility that boasts unparalleled performance parameters.

The successful operation of the 660 MW ultra-supercritical CFB boiler represents a monumental step forward on the global technology spectrum, reinforcing Harbin Electric Corporation's pioneering position in large-capacity, high-parameter CFB technology. This achievement initiates a new era of ultra-supercritical parameters for CFB boilers around the world.
