世界首台660兆瓦超超临界循环流化床锅炉通过鉴定

Core Insights - The world's first 660 MW high-efficiency ultra-supercritical circulating fluidized bed power generation project has successfully completed its first year of safe operation and has passed authoritative evaluation, achieving performance indicators that meet or exceed design values, marking a significant breakthrough in clean power generation technology in China [1][3]. Group 1: Technology and Performance - The boiler, likened to the "heart" of a thermal power plant, directly influences power generation efficiency and environmental standards. The newly evaluated boiler has achieved a core breakthrough in high-efficiency ultra-supercritical circulating fluidized bed technology [3]. - The "ultra-supercritical" technology allows water to be heated to over 600°C and pressurized above 29 MPa, significantly enhancing the efficiency of converting heat into electrical energy [3]. - The "circulating fluidized bed" technology enables better combustion by allowing fuel to be continuously agitated and heated, improving combustion efficiency and enabling the addition of desulfurization agents to reduce pollution [3]. Group 2: Environmental Impact and Resource Utilization - The project can convert approximately 2 million tons of low-calorific-value fuels, such as coal slurry and gangue, which are typically considered waste, into usable energy each year, thus addressing waste management issues [5]. - The boiler's deep load-following capability allows it to operate stably under low-load conditions, effectively smoothing out fluctuations in renewable energy sources like wind and solar, thereby enhancing the grid's capacity to absorb renewable energy [5]. - The power generation capacity is projected to reach 3.3 billion kWh annually, providing stable and sufficient power support to the grid [5].
