摘要
蒸汽冷却器是汽轮机高压加热器回热系统中重要的设备之一,利用汽轮机抽汽加热锅炉给水的一种装置。蒸汽冷却器的设计至关重要,它的设计成功与否直接关系到回热系统的热效率及蒸冷下一级高压加热器的安全。
Steam Cooler is important auxiliary equipment in the reheateing system of turbine generator unit. It is a device that uses the extraction steam of turbine to heat the boiler feed water. The design of Steam Cooler is success or not, that direct affect the back heating system ratio and the next HP heater security.
