In the modern energy production system, thermal power plants are widely used, and the stable operation of the core equipment boiler affects the safety and efficiency of power supply. The water quality of the boiler is crucial to avoid scaling, corrosion, and ensure steam quality. Therefore, thermal power plant boiler water testing has become a key link to ensure efficient and safe operation of the equipment.

Water is the lifeline of thermal power plants. It not only serves as a carrier of thermal energy, but also directly participates in the energy conversion process. Poor water quality can lead to the following problems:Scaling: 

1、Water with higher hardness tends to precipitate minerals at high temperatures, forming hard scale, which reduces heat exchange efficiency and increases energy consumption.

2.Corrosion: Improper water quality will accelerate the corrosion of boiler metal parts, shorten equipment life, and even cause safety accidents.

3.Degraded steam quality: Water quality issues can affect the purity of steam, which in turn affects the operating efficiency of the steam turbine and the quality of power output.

Various indicators of water and boiler water, including but not limited to pH value, hardness, alkalinity, dissolved oxygen, chloride ions, phosphates, etc., are designed to be strictly managed through water quality. The boiler water quality testing and analysis equipment series developed by Erun Environmental Protection is designed and produced according to the national boiler water quality standards. It can detect various indicators in the water and prevent the occurrence of the above problems.

1、Laboratory boiler water testing methods: including chemical titration (such as alkalinity and hardness determination), colorimetry (such as iron and copper content detection), conductivity measurement (total dissolved solids assessment), etc. These methods are easy to operate and low cost. ERUN-ST laboratory and ERUN-SP portable boiler water quality testing and analysis equipment can be used, which are suitable for daily monitoring, laboratory analysis, and mobile monitoring.

2、Online monitoring: With the advancement of technology, more and more thermal power plants are using online water quality monitoring systems to monitor water quality parameters in real time, such as pH, conductivity, dissolved oxygen, etc., to detect water quality abnormalities in a timely manner and respond quickly. You can refer to Erun Environmental Protection's boiler water online monitoring and analysis equipment. If you need specific information, please consult the website's online customer service.

The above is the relevant content of boiler water testing in thermal power plants.
