摘　　要：热网加热器常偏离设计工况运行,偏离设计值低参数运行将严重影响热网加热器的使用寿命。分析了低压运行时设备损坏的原因,提出了调整热网加热器的循环水量、提高热网加热器循环水出口温度的措施,使热网加热器的蒸汽压力接近设计值,以保证热网加热器安全运行。Heat network heaters usually operate under different working condition from design condition.This could significantly shorten life span of heaters.Equipment damage causes were analyzed.The treatment of increasing circulating water quantity and inlet temperature was indicated to made heater steam pressure closer to design value.Operational safety of heat network heater was ensured.

关 键 词：热网加热器 低压运行 蒸汽压力 循环水量 循环水出口温度
