This first-of-its-kind field study investigated the use of film-forming products to reduce off-line corrosion in a steam turbine’s phase transition zone. Researchers exposed carbon and stainless steel specimens to low-pressure steam from a feedwater heater on a supercritical unit. Contaminants and various film-forming products were injected into the steam.
This study examined corrosion rates of carbon steel and a copper alloy under simulated power plant feedwater conditions after application of various commercial filming products.
Filming and Neutralizing Amine Application Continuous Service in Fossil Plants and Heat Recovery Steam Generators: Bethlehem Energy Center
This case study summarizes the efforts of the 780-megawatt combined cycle Bethlehem Energy Center plant to optimize corrosion control with ammonia, neutralizing amines, and filming amines.
During power plant outages, personnel can examine major components of the steam/water cycle for chemistry-related or mechanical damage that may affect the chemistry on critical equipment. Using photos and illustrations, this field guide provides instructions on what to look for when performing visual inspections of components that are often only accessible during outages.
