As an indispensable and important equipment in industrial production, the operating efficiency and safety of the boiler are directly related to the smoothness of the entire production process. The control of boiler water quality, especially the adjustment of pH value, is one of the key factors to ensure the safe, stable and efficient operation of the boiler.This article will explore in depth what is the normal pH value of boiler water, why it is necessary to test the pH value, and the applications and advantages of pH testers produced by Erun Environmental Protection in various industries.
The main purpose of testing the pH value of boiler water is to control the acidity and alkalinity of the water, thereby preventing corrosion, scaling, fouling and other problems caused by poor water quality. The pH value is an indicator of the acidity and alkalinity of a solution, which reflects the concentration of hydrogen ions in the water. The pH value in boiler water not only affects the corrosion rate, but also affects the formation of sediments and steam quality.Therefore, regularly testing and adjusting the pH value of boiler water is an important measure to ensure the long-term stable operation of the boiler.
1.Prevent corrosion: If the pH value in boiler water is too low, it will accelerate the corrosion of the metal surface, destroy the protective oxide film, and shorten the service life of the boiler. The appropriate pH value can form a protective film to slow down the corrosion process.
2. Reduce scaling: High pH helps phosphate and calcium ions combine to form easily discharged water slag, thereby inhibiting the hydrolysis of silicates, reducing scale formation and improving the heat transfer efficiency of the boiler.
3. Ensure steam quality: The appropriate pH value can ensure the purity of the steam and avoid the deterioration of steam quality due to water quality problems, which will affect the subsequent production process.
In order to meet the needs of different industries, we have produced various types of pH testers, including desktop, portable, online, etc., each with its own characteristics, widely used in various industries.
The desktop pH analyzer adopts embedded system design, integrating signal acquisition, data processing and display functions, with high intelligence, accurate measurement and easy operation. It is widely used in power, petrochemical, food and beverage, papermaking and other industries, and can also be used for teaching and scientific research in colleges and universities and scientific research institutions.
The portable pH meter is light and easy to carry, suitable for rapid on-site testing. It is widely used in environmental protection, swimming pools, aquariums, food, cosmetics, soilless cultivation, breeding and other industries, providing users with flexible and convenient water quality monitoring solutions.
The online pH tester has the functions of real-time monitoring, automatic calibration, data recording, etc., which can greatly improve the efficiency and accuracy of water quality testing. It is widely used in sewage treatment plants, drinking water plants, industrial raw water treatment and other occasions. By real-time monitoring of the pH value in water, adjusting the management and control system, it ensures stable water quality and up-to-standard discharge.At the same time, online pH detection instruments can also help optimize the boiler water treatment process. Based on historical data analysis, the proportion and type of added reagents can be adjusted to achieve the best water quality balance.
1. Natural circulation steam boilers and steam-water dual-purpose boilers with in-boiler water treatment: the feed water ph value is between 7.0 - 10.5 and the boiler water pH value is between 10.0- 12.0.
2.Hot water boiler: the feed water pH value is between 7.0-11.0, and the pH value of the pot water is between 9.0-12.0.
3.Flow-through steam boiler: the feed water pH value is between 7.0-9.0, and the pot water pH value is between 10.0-12.0.
These ranges indicate that the pH value of boiler water should be controlled within a weak alkaline range to ensure safe, stable and efficient operation of the boiler.
The detection and adjustment of the pH value of boiler water is crucial to ensure the safe operation of the boiler. By regularly detecting and adjusting the pH value of boiler water, corrosion, scaling and other problems can be effectively prevented, and the heat transfer efficiency and steam quality of the boiler can be improved.The desktop, portable and online pH testers we produce meet the needs of different industries for water quality testing with their respective advantages, and provide a strong guarantee for the safe operation of boilers. In the future, we will continue to be committed to the research and development and innovation of water quality testing technology, and provide more accurate and efficient water quality testing solutions for more users.
