Abstract

The reliability and economy of thermal power plant equipment, including combined-cycle plants, are affected by corrosion of structural materials and deposit formation in the water-steam circuit. To reduce the rate of these processes, coolant treatment is used. Ammonia, hydrazine, phosphates, etc. have been traditionally used as reagents. Recently, much attention has been paid to the use of water chemistry with the addition of complex reagents based on film-forming amines, not only for the equipment protection during the established operation mode but also for start-stops and preservation. Such water chemistry regimes are used not only in Russia but also in other countries for steam turbine and combined-cycle TPP, including biomass TPPs. The International Association for the Properties of Water and Steam, uniting specialists from all over the world, developed a guideline in 2016 for the use of such reagents based on theoretical studies and years of operational experience in power equipment in 21 countries. The review of domestic and international guidelines containing conditions for the use of film-forming amines and amine-based reagents for the organization of TPP water chemistry regimes for steam turbines and combined-cycle plants is presented.
