Abstract
Measurements on air-cooled reflux steam condensers or dephlegmators at different power plants have shown that sections of these units do not transfer heat effectively over a range of operating conditions. The ineffective areas may be due to flooding in the finned tubes although entrainment of the condensate in certain steam inlet manifolds is usually the main reason for the poor performance. Laboratory experiments were conducted to show under which conditions entrainment occurs, as well as the pressure drop and flow characteristics for different types of inlet headers or manifolds. A practical and cost effective solution is proposed to eliminate the reduction in dephlegmator performance due to entrainment in a particular manifold.
