4. Steam and Water Analysis System
4.0.1. Basics of Steam and Water Chemistry with Measurements and Controls
Modern power plants, especially steam turbines, have extremely low tolerance for any deposition and contamination. Water chemistry plays a vital role in achieving maximum efficiency with minimum downtime. To make the discussions on SWAS more meaningful, it is better to discuss steam and water chemistry beforehand. Contaminations in FW mainly comes from the following:
• Make-up water from demineralization (DM) plants (malfunctioning)
• Circulating water (CW) from condenser leakage (severe for sea water cooling)
• Conditioning chemical such as NH3/N2H4 (residual to be removed)
• Corrosion products (Fe, Cu, etc.) formed in FW system
• Recycling ...
