Jun 12, 2019 · In power plants and boiler systems, one practical use of ORP measurement is to monitor hydrazine and carbohydrazide in the steam-water cycle to minimize corrosion. Hydrazine is a chemical compound that acts as a reducing agent in water systems. It prevents corrosion by reacting with oxygen to form nitrogen gas and water.Learn More
Cycle Chemistry –Why is it important? "It is clear that the major Boiler/HRSG failure mechanisms are driven by thermal and/or cycle chemistry influences" (EPRI, 2003) Effective cycle chemistry monitoring and control is required to: Operate plant safely. Protect plant integrity. Meet legal requirements, e.g. PSSR. Maintain reliability and availability.Learn More
