What does it take to set a new benchmark in power generation? Harbin Electric Corporation has delivered the answer with the world’s first 660 MW high-efficiency ultra-supercritical circulating fluidized bed (CFB) power generation unit. Recently completing a 168-hour full-load trial operation, this technological feat, located in Binchang, China, is setting unparalleled standards in energy efficiency and ecological innovation.
The Binchang Project: A Model for Sustainability and Efficiency
Endorsed by the Ministry of Science and Technology and the National Energy Administration, the Binchang Project is more than just a power plant. It embodies a vision of sustainable coal-powered energy. By combining solid waste and mine water utilization with geological restoration and land reclamation, the project is a cornerstone of ecological restoration efforts in the Yellow River Basin.
When fully operational, the first phase of the project will annually convert approximately 2 million tons of low-calorific value coal and inferior fuels like coal slime and gangue. It will also utilize 2 million tons of mine water, producing 6 million GJ of heat to meet the heating and industrial steam needs of Binzhou City. Beyond this, the project will stabilize the regional power grid, address local power shortages, and drive socio-economic growth in the area.
Engineering Prowess: Core Components at the Forefront
Harbin Electric Corporation has designed and manufactured the boiler, turbine, and generator for the Binchang Project, creating a trifecta of engineering excellence.
- CFB Boiler: Developed by Harbin Boiler Company, this ultra-supercritical boiler achieves record-breaking parameters with ultra-low emissions, ultra-high performance, and ultra-low energy consumption. Its main steam pressure reaches an astonishing 29.3 MPa—equivalent to the weight of four adults standing on a nail-sized section of pipe. With a main steam temperature of 605°C and a reheat steam temperature of 623°C, it has set new global benchmarks. The boiler’s desulfurization efficiency of 95% ensures ultra-low emissions, making it an industry leader in environmental performance.
