Abstract

Erosive damage to the low-pressure condensing turbine through which wet steam flows, are due to the presence of relatively large droplets from formed film formed on the surface of the vanes. To limit the formation of water fllm on the blade surface and thereby reduce the amount of large particles carried by the pair, they proposed a method based on heating steam from inside the guide vanes. The heating steam is condensed inside the blade releasing heat of evaporation through the wall of the film, causing its partial or total evaporation.
