| 摘 要： | 研究了超临界及超超临界机组运行中的一些特殊问题,如高蒸汽参数对锅炉、汽轮机启动及变负荷运行特性影响;机组的旁路系统、机组低负荷运行、负荷变化范围、负荷阶跃、负荷变动率、启动时间等运行特性等。文章认为超超临界机组运行在60%~100%负荷范围内比较经济合理,其效率仅下降2·3%。

| Abstract: | Some special issues in the operation of supercritical and ultrasupercritical pressure generating units were studied,such as:the impacts of high steam parameters on the startup and variable load operation properties of boiler and steam turbine;bypass system of unit;low load operation,variation range of load,load step change,load variation rate,startup time of uuits etc. operation properties. the paper put forward the suggestions on the economic operation load of ultrasupercritical pressure units,having reference value for the safe and economic operation of units. |
