Consensus on Operating Practices for the Sampling and Monitoring of Feedwater and Boiler Water Chemistry in Modern Industrial Boilers (CRTD-81)
Download citation file:
All units and sub-systems in the power train of industrial, utility and heat recovery steam generation facilities must be adequately sampled and monitored to maintain operation as desired and to prevent damage to individual pieces of equipment. Besides the obvious effects of failure to maintain design production of treated water and steam on plant production costs, failure to adequately monitor operating conditions can cause failure of major system components and cause unplanned outages.
This document has been prepared by the Water Technology Subcommittee of the ASME Research and Technology Committee on Water and Steam in Thermal Systems. This publication provides recommendations for water chemistry monitoring and is a companion to the ASME “Consensus on Operating Practices for the Control of Feedwater and Boiler Water Chemistry in Modern Industrial Boilers,” “A Practical Guide to Avoiding Steam Purity Problems in the Industrial Plant,” and “Consensus on Operating Practices for Control of Water and Steam Chemistry in Combined Cycle and Cogeneration Power Plants”. These documents provide guidance for avoiding the penalties of severe corrosion or deposition in steam generation systems and their auxiliary steam user equipment.
