摘要
可再生能源迅速发展对火电机组深度调峰提出了更高要求,机组调峰性能不仅是影响火电厂经济效益的重要因素,而且对于中国促进能源低碳转型有非常重要的战略意义.充分挖掘煤粉机组的深度调峰潜力与快速变负荷能力,对中国现有的煤粉机组调峰技术进行总结和分析,可为今后煤粉锅炉发电机组深度和灵活调峰技术的研发提供参考.对福建省一电厂 1 050 MW超超临界前后墙对冲燃煤机组从 100%至 20%负荷状态下的运行情况进行了试验研究,在试验过程中记录了锅炉、汽轮机、发电机相关运行参数并进行了分析.结果表明,该锅炉在无投油的情况下,20%负荷稳燃能力良好,为运行深度调峰提供了参考.
Abstract
The rapid development of renewable energy has put forward higher requirements for deep peak shaving of thermal power units.The peak shaving performance of units is not only an important factor affecting the economic benefits of thermal power plants,but also of great strategic significance for China to promote energy low-carbon transformation.Fully tapping into the deep peak shaving potential and rapid load changing capacity of coal-fired power units,summarizing and analyzing the existing peak shaving technologies of coal-fired power units in China,can provide reference for the future research and development of deep and flexible peak shaving technologies for coal-fired boiler generator units.An experimental study was conducted on the operation of a 1 050 MW ultra-supercritical front and rear wall opposed coal-fired unit in a power plant from 100%to 20%load state.During the test,relevant operating parameters of the boiler,turbine,and generator were recorded and analyzed.The results show that the boiler has good stable combustion ability at 20%load without oil injection,providing a reference for deep peak shaving operation.
