Note : periodic relief valve discharge may occur on dead end service applications , such as boiler feed lines or cooling tower makeup lines 注意：在终端应用中，如锅炉给水管线或冷却塔补水管线，安全阀可能会出现周期性排放。
By ensuring that there is no contact between the condensate and the coolant , a pure distilled water can be produced which is ideal for boiler feed water 通过确保冷却液与冷凝物之间完全没有混合，我们又得到了对于锅炉用水来说最理想的纯净蒸馏水。
The economic advantages of taking account of the covariance between nutrients in boiler feed ingredients were investigated through a hypothetical example 摘要本文透过仿真程序，针对肉鸡饲料原料中营养素间的共变异数性质从所可能?生的经济效果进行研讨。
