摘要
根据国电泰州电厂二期工程调试的实际情况,介绍了上海汽轮机厂制造的1 000 MW双再热汽轮机启动运行的步序,就启动调试过程中存在的主要问题,如排汽温差大,暖机时间长,低压外缸温度高和双缸启动不成功进行分析和处理,对部分控制逻辑和包括蒸汽参数及调节汽门开度的启动参数进行优化,实现了机组高效节能运行和超低排放,对超超临界双再热汽轮机的启动试运具有一定的参考意义。
Based on the actual tuning process of the steam turbines in the second-phase project of Guodian Taizhou Power Plant, the startup procedures of the 1000-MW uhra-supercritica[ turbines with double reheat cycles manufactured by Shanghai Turbine Company is presented, and the problems exposed in the process are analyzed with the corresponding solutions proposed, such as large exhaust steam temperature deviation, long warm-up time, high LP outer casing temperature and unsuccessful double casing startup. In addition, some control logics and the startup parameters of steam temperature and pressure as well as governing valve opening are optimized, which makes the turbine operation more energy-efficient with ultra-low emissions. This case can provide applicable guidance for the tuning and trial operation of double reheat ultra-supercritical steam turbines.
