In the present work, based on the mechanism of low - temperature corrosion, an opinion was presented by theoretical analysis and computation, that is the vacuum boiler can not avoid being corroded completely under low temperature, but the corrosion is very weak no matter if the exhaust gas temperature is higher than the flue gas dew point; it was obtained the relationship between the corrosion velocity of metal wall and wall temperature along gas pass of vacuum boiler, and the one between the corrosion velocity of metal wall and wall temperature under the condition that the flue gas temperature is lower than the acid dew point.

文章从锅炉发生低温腐蚀的机理人手，通过理论分析计算并通过实践检验，提出了真空相变锅炉虽然不能完全避免低温腐蚀问题，但不论排烟温度是否高于烟气露点，低温腐蚀的程度都很弱的观点；给出了真空相变锅炉沿烟气流程金属壁面的腐蚀速度与壁面温度的关系曲线，和烟气温度低于酸露点时金属壁面的腐蚀速度与壁面温度的关系曲线；同时，文章推荐真空相变锅炉的设计排烟温度取130℃左右的低排烟温度。
