700℃超超临界燃煤发电技术研究现状
Research progress of advanced 700 ℃ ultra-supercritical coal-fired power generation technology
摘要
Abstract
The advanced 700 ℃ ultra supercritical (A-USC) power generation technology can dramatically enhance the power generating efficiency of the units, realize energy conservation and emission reduction, which has great strategic significance. The key problems need to be solved during developing the 700 ℃ A-USC tech-nology were presented and analysed in this paper, including the preparation of high temperature alloy materials, manufacturing of key high temperature components for boilers and steam turbines, manufacturing of high temperature valves, actual furnace verification test for high temperature materials and key components, and design/building/operation of 700 ℃ A-USC demonstration power stations. Currently, the research and develop-ment of domestic 700 ℃ A-USC technology in accordance with the plan steadily, which has already obtained phased progress in aspects of preparation of nickel-based high temperature materials, production of key components, main equipment scheme study, and construction of key components' verification platform. Developing the 700 ℃A-USC technology will greatly promote the development of China's industrial materials, electric power industry and equipment manufacturing industry关键词
