火电机组预防主/再热蒸汽超温的方法

Methods of Preventing Over-Temperature of Main/Reheat Steam in Thermal Power Units

主/再热蒸汽温度是火电机组一项重要的运行参数,随着电厂考核的加大,火电厂面临着设备老化、调节性能下降等一系列问题。文章试从在保证新蒸汽温度高度要求的前提下,多角度剖析主/再热蒸汽温度指标提高过程中防止超温的方法。

The main/reheat steam temperature is an important parameter in thermal power unit operation.With the assessment strengthening,thermal power plant is faced with a series of problems,such as aging equipment and degraded regulatory performance.On the premise of meeting the requirements of new steam temperature,this paper conducts a multi-angle study into the methods of preventing over-temperature in the process of increasing the temperature.
