Air Leakage - an overview | ScienceDirect Topics

7.1.1 Locating air leaks. Air leakage can occur in any part of the condensing system which operates near or below atmospheric pressure, and is often caused by failure of joints, at flanges, and also by weld and material failures. When the turbine is off-load, detection of air leakage is made in some parts of the system by flooding with water.Get price
