Improved apparatus for separating out droplets of liquid entrained in a gas or a vapour

摘要

A moisture separator comprising blocks of spaced-apart, mutually parallel corrugated plates wherein the undulations of the corrugated plates have a wavelength or period P in the range 6mm to 24mm and amplitude, A, which is about half the period P. Ideally, the gap G between adjacent corrugated plates in the moisture separator should be about the same as the amplitude A. The wavelength of the corrugations is preferably 9mm to 18mm. The separator may be used to separate liquid droplets entrained in gas or vapour and is ideally employed to remove droplets of water from steam that is used to drive turbines. Preferably, the width of the each corrugated plate, measured in the direction of the flow of the incident gas or vapour, is 10 times the wavelength.
