This document provides recommendations for the sampling and analytical testing required to maintain the suggested water chemistry limits outlined in the “Consensus on Operating Practices for the Control of Feedwater and Boiler Water Chemistry in Modern Industrial Boilers” and the “Consensus on Operating Practices for Control of Water and Steam Chemistry in Combined Cycle and Cogeneration Power Plants.”
The boilers covered by these recommendations are:
• industrial water tube, high duty, primary fuel fired, drum type with superheaters and∕or process restrictions on steam purity
• industrial water tube, high duty, primary fuel fired, drum type without superheaters
• industrial fire tube, high duty, primary fuel fired
• industrial coil type, water tube, high duty, primary fuel fired
• marine propulsion, water tube, oil fired, drum type
• electrode type, high voltage, recirculating jet type
• single pressure industrial heat recovery steam generators
