摘要 为适应国内火电机组向高参数发展的需求,研发31 MPa/600℃/620℃/620℃的1 000 MW超超临界汽轮机是充分必要。汽轮机结构科学的选型是保证整个机组效率及安全性的首要条件。通过对进汽参数合理的分析,保证技术的成熟可靠,最终确定超高压、高压、中压、低压模块,并且对整个机组轴系、滑销系统等充分考虑,保证了机组各方面的成熟可行性,并为后续更高参数机组开发提供了有效的理论支撑。 In order to meet the needs of domestic thermal power units to develop to high parameter, the research and development of/620 ℃/620 ℃ 31 Mpa/600 ℃ 1000MW ultra supercritical steam turbine is necessary and sufficient. The type selection of turbine structure is the first condition to ensure the efficiency and safety of the whole unit. Through the steam parameters and reasonable analysis, to ensure that the technology is mature and reliable, and ultimately determine the ultra high-voltage, high-voltage, medium voltage and low voltage module, and the entire unit shaft, a sliding pin system fully considered, ensure the unit the mature feasibility, and for the following high parameter unit development provides effective theoretical support
