Core Insights - China's energy sector has achieved significant breakthroughs with the world's first 660 MW ultra-supercritical circulating fluidized bed boiler passing certification, the first domestic 1500℃ single-shaft heavy-duty gas turbine reaching full capacity, and the full commissioning of the Meizhou pumped storage power station phase II, marking important advancements in clean energy technology and enhancing energy security [1][2][8]. Group 1: Breakthroughs in Boiler Technology - The world's first 660 MW ultra-supercritical circulating fluidized bed boiler has been certified, achieving or exceeding all performance indicators, thus filling a global industry gap and representing a major breakthrough in clean power technology [2]. - This boiler operates at pressures above 29 MPa and temperatures over 600℃, significantly improving the efficiency of converting heat into electricity [2]. - The boiler can utilize low-calorific fuels such as coal slurry and gangue, converting approximately 2 million tons of waste into usable energy annually, while also stabilizing the power grid against fluctuations from renewable energy sources [4]. Group 2: Advancements in Gas Turbine Technology - The first domestic 1500℃ single-shaft heavy-duty gas turbine project has been fully commissioned, filling a gap in the domestic "F" class improved single-shaft heavy-duty gas turbine market [5]. - The project has achieved a 20% reduction in plant area and a 2% increase in efficiency compared to similar units, with nitrogen oxide emissions meeting national standards [7]. - It is estimated that the project will reduce carbon dioxide emissions by approximately 520,000 tons annually, while also decreasing standard coal consumption by about 200,000 tons [7]. Group 3: Development of Pumped Storage Power Stations - The Meizhou pumped storage power station phase II has been fully commissioned, supporting power supply and green transition in the Guangdong-Hong Kong-Macao Greater Bay Area [8][10]. - With a total investment of approximately 12 billion yuan, the power station has a total capacity of 9.2 million cubic meters, equivalent to the size of 6.5 West Lakes, and adds 2.4 million kilowatts of regulation capacity [8]. - The project is noted for its high level of domestic equipment localization, achieving full domestic production of main equipment and control systems [10].
