摘要(Abstract)：

针对宁海A电厂600 MW机组低负荷段再热汽温偏低的问题,提出了优化燃烧器摆角、磨组、配风、吹灰组合等技术手段,并在低负荷进行了试验,找出最佳运行工况,验证了机组在稳定工况下的再热汽温能达到额定值。
Aiming at low reheat steam temperature of 600 MW units in Ninghai A Power Plant in low load period,the paper proposes optimization of tilt angle,pulverizers,distributed air and sootblowing;furthermore,the test was conducted in low load period and the optimal working condition was sought out.It is proved that under stable working condition of units the reheat steam temperature of boiler can reach the rated value.
