Various water droplet separators are being used in power plants, chemical plants and others. Of these separators, the eliminator, which is made of thin plates bended to make zig-zag flow passages, is comparatively simple and high performance. In this report, the separation performance of the eliminator is theoretically analysed. The efficiency ηd, of catching water droplets is given by the following equation: ηd=DN(β)/p* where, DN(β)=1-β/1n(1/β)(1+1-βN/1+β) N = number of bending If N is an odd number, use N-1 instead of an index number N. β= function of water droplet diameter, air velocity, bending plate length and bending angle p= dimensionless pitch of eliminator The separation efficiency is 100% for water droplets which are larger than the droplet diameter satisfying DN (β) = p. In other words, such droplets will be separated completely. If the size distribution of droplets is known at the inlet to the eliminator, the separation efficiency ηN of the eliminator is given by the following equation: ηN=1-Σf(1-ηd)Dp where, f = size distribution of droplets at the inlet to the eliminator.
