Abstract

The hardness of boiler water is a crucial indicator that affects the safe and economic operation of boilers, making accurate and efficient monitoring of it essential. This research project systematically investigates the primary methods for detecting water hardness, delving into their principles, operational procedures, application costs, and accuracy. By integrating the specific environmental factors of industrial boiler applications, the project aims to develop a novel, efficient, and precise method for measuring boiler water hardness. This endeavor provides a theoretical foundation and technical support for the research and development of an on-line detection system for industrial boiler water quality.
