     the features of erosion-corrosion wear (ecw) in a low-pressure evaporator (lpe) combinedcycle plant (ccp) at high void factor values in the heat carrier are considered. it is shown that if the medium pressure in the evaporator is less than 1 mpa and steam quality x ≈ 0.5, the void fraction β is close to 1, at the outlet of the evaporator almost dry saturated steam moves, and the formation of liquid films is excluded. under these conditions, the wear of the evaporator coil sections has an erosive nature, caused by high velocity steam, carrying the dense particles of corrosion products and large drops of water, previously plucked from the surface of the liquid films.
