Steam Turbine Deposition, Erosion, and Corrosion - SUEZ Water
Water Handbook - Steam Turbine Deposition, Erosion - SUEZTurbine deposition; Erosion; Corrosion; The development of modern, high-efficiency steam turbines has led to an increase in deposition, erosion, and corrosion problems. Close tolerances in the turbines, the use of high-strength steels, and impure steam all contribute to these conditions. TURBINE DEPOSITIONWater Handbook - Steam Purity | SUEZSolid particles in steam can erode turbine parts, while deposition on turbine blades can reduce efficiency and capacity. Losses of 5% in turbine efficiency and 20% in turbine capacity have occurred due to deposition. When large slugs of boiler water carry over with steam, the resulting thermal and mechanical shock can cause severe damage.Water Handbook - Measurement of Steam Purity | SUEZSUEZ&39;s boiler water internal treatment programs provide highly effective protection against corrosion and scale formation to ensure optimum performance and availability of our your steam system while reducing the total cost of ownership and environmental footprint through energy and water savings.Handbook of Industrial Water Treatment | SUEZChapter 18 - Steam Turbine Deposition, Erosion, and Corrosion; Chapter 19 - Condensate System Corrosion; Chapter 20 - Fireside Preboiler Systems; Chapter 21 - Boiler Fireside Deposit and Corrosion Control; Chapter 22 - Coil-end Deposition and Corrosion Control; Cooling Water Systems.

Water Handbook - Chemical Cleaning Of Steam - SUEZPower and water plant operators play a big part in the deposit control of a unit. Corrosion product deposits are the major contaminant in high-pressure boilers using demineralized makeup water. Condensate and feedwater system corrosion products can be carried into the boiler, where they can deposit on the metal surfaces.

Water-Droplet Erosion - an overview | ScienceDirect TopicsH. Nomoto, in Advances in Steam Turbines for Modern Power Plants, 2017. Abstract. There are two kinds of erosion in steam turbines, one is the solid particle erosion that occurs at the inlet stage of the steam turbine, and the other is the water-droplet erosion that occurs in the latter stages of the low-pressure turbine where moving blades are operated in a wet steam region.
Preventing Copper Deposition in Steam TurbinesCorrosion products may be physically washed off piping by high steam or water flows, exfoliated because of thermal shock, or dissolved because of the chemistry of the feedwater or steam.
