Application of pH and Conductivity Sensors in Boiler Water Monitoring in the Paper Industry

Shanghai Botuo Instrument Co., Ltd. produces pure water pH meters and pure water conductivity for water quality testing of boiler water and condensate water. If you have any project needs, please feel free to contact usSales Engineer:Wang Yuzhang, consultation.

A paper industry limited liability company located in Hubei was established in 1999 and was restructured as a joint-stock limited liability company in December 2008 One of the enterprises specializing in the production of household paper series products, with multiple brands commonly found in domestic household hygiene and cleaning paper.

Water is a crucial component throughout the entire production process of the pulp and paper industry. Paper companies have high requirements for water quality. The quality of water has a certain impact on the quality of pulp and paper, such as capacitor paper, electrical insulation paper, and synthetic silk pulp, which require higher water requirements than general production water. The water in the paper mill will be treated by boilers, and the quality required for boiler water in the boiler water treatment process is higher. Because hard water can cause boiler scaling and affect heat transfer. The oxygen, carbon dioxide, and chloride ions in water have an erosive effect on the boiler wall. These impurities have a slightly higher content and are not conducive to the operation of the boiler.

Therefore, the quality of boiler water has a significant impact on both the boiler itself and the quality of papermaking. The conventional monitoring indicators for boiler water include pH, temperature, conductivity, hardness, and dissolved oxygen. The paper mill in Hubei used our company's in the monitoring of boiler water qualityPH meterandConductivity analyzerAt present, it is running well, providing real-time basis for the water treatment and stable operation of the paper mill boiler. In the future, a hardness tester will be added to monitor the water quality of the boiler water in real time.
