Yingrun Group Boiler Water Quality Monitoring System Helps Pubai Thermal Power Company Improve Efficiency | Intelligent Upgrade Case

In the wave of digital transformation in the energy industry, boiler water quality monitoring, as a key link to ensure power generation safety and efficiency, is undergoing a leap from traditional manual detection to intelligent online monitoring. Xi'an Yingrun Environmental Protection Technology Group Co., Ltd. (hereinafter referred to as "Yingrun Group"), with its independently developed boiler water quality online monitoring and analysis system, has successfully provided intelligent solutions for the water quality management of the fourth and fifth boilers of Shaanxi Shaanxi Coal Pubai Mining Co., Ltd. Thermal Power Company (hereinafter referred to as "Pubai Thermal Power Company"), achieving an upgrade from laboratory manual sampling to full process automated monitoring, and setting a classic example of high efficiency and energy conservation for the industry.

★Pain points and challenges of traditional detection mode

As an important energy supply enterprise in the region, Pubai Thermal Power Company's boiler operation stability directly affects power generation efficiency and equipment life. Previously, the company used laboratory manual sampling and testing to monitor key parameters such as pH, conductivity, alkalinity, hardness, phosphate ions, and dissolved oxygen of five types of water vapor: boiler feedwater, boiler water, saturated steam water, superheated steam water, and deoxygenated water. However, this model has significant limitations:

Low detection efficiencyManual sampling requires daily scheduled and fixed-point operations, which take several hours from sampling to laboratory analysis, making it difficult to grasp changes in water quality in real time;

Data lag riskFailure to issue timely warnings when water quality is abnormal may lead to boiler scaling, corrosion, or a decrease in steam quality, posing a threat to equipment safety;

High labor costsLong term reliance on manual operations not only increases the burden on the operations team, but also poses a risk of human error.

These issues directly constrain Pubai Thermal Power Company's progress towards intelligent and refined management.

★Win Run Solution: Fully Automated Monitoring System for the Entire Process

In response to the above pain points, the boiler water quality online monitoring and analysis system provided by Yingrun Group is centered on "real-time monitoring, precise control, and intelligent warning", and achieves full process automation through software and hardware collaboration:

Multi parameter online monitoringThe system integrates high-precision equipment such as pH sensors, conductivity meters, and ion chromatography analysis modules, which can simultaneously monitor the pH value, conductivity, total alkalinity, phenolphthalein alkalinity, total hardness, phosphate concentration, and dissolved oxygen content of boiler feedwater, boiler water, saturated steam water, superheated steam water, and deoxygenated water, covering key water quality indicators throughout the entire boiler operation cycle.

Intelligent control and data linkageThe system reduces manual intervention by automatically controlling the processes of water inlet cooling, automatic sampling, automatic dosing (such as phosphate regulator), and automatic sewage discharge. Real time upload of detection data to the cloud platform, seamlessly integrating with the existing DCS system of Pubai Thermal Power Company to achieve data visualization and remote monitoring.

Abnormal Warning and Decision SupportBased on preset thresholds, the system can automatically trigger alarms and push them to the mobile end of operation and maintenance personnel, while generating water quality trend analysis reports to assist in optimizing boiler operating parameters, reducing energy consumption and maintenance costs.

★Technical highlights and implementation effectiveness

The core technological advantages of Yingrun Group's project are reflected in the following aspects:

High precision sensors and algorithm optimizationAdopting imported electrochemical sensors and independently developed dynamic calibration algorithms, the measurement error of pH, dissolved oxygen and other parameters is ensured to be ≤± 0.02, and the detection accuracy of phosphate concentration reaches 0.1mg/L, meeting the requirements of the "GB/T 1576-2022 Industrial Boiler Water Quality" standard.

Automatic cleaning and anti fouling designThe system is equipped with an automatic backwash function, which can periodically clean the sensor probe, reduce residual interference from water samples, and extend equipment life. For high alkalinity and high hardness water samples, corrosion-resistant materials and sealing structures are used to ensure long-term stable operation.

Modular design and rapid deploymentThe system supports multi-channel expansion, and Pubai Thermal Power Company completed installation and debugging in just one week, quickly achieving parallel monitoring of five types of water vapor.

After the implementation of the project, Pubai Thermal Power Company achieved significant results:

Efficiency improvementThe daily manual sampling frequency has been reduced from 6 times to 1 time, and the number of operation and maintenance personnel has been reduced from 3 people/shift to 1 person for inspection, resulting in a 60% reduction in labor costs;

Real time data enhancementThe frequency of updating water quality parameters has been increased from hourly to minute level, and the response time for abnormal situations has been reduced by 80%;

Extended lifespan of equipmentBy precisely controlling the concentration of phosphate ions (maintaining 2-10mg/L), the formation of boiler scale is effectively suppressed and the frequency of acid washing is reduced; Control the dissolved oxygen concentration below 0.01mg/L to reduce the risk of oxygen corrosion, and estimate a 15% reduction in annual maintenance costs;

energy consumption optimizationThe system automatically adjusts the dosage based on conductivity and hardness data, reducing chemical waste and saving approximately 200000 yuan in chemical costs annually.

★Industry Value and Future Prospects

The success of the Pubai Thermal Power Project not only reflects the technical strength of Yingrun Group, but also provides a replicable intelligent upgrade path for the energy industry:

Security and Compliance AssuranceThe system data is traceable, meeting the compliance requirements of environmental protection departments for water quality monitoring and reducing operational risks;

Energy saving and consumption reducing demonstration effectReduce energy waste through precise control and assist enterprises in achieving their "dual carbon" goals;

Whole life cycle managementA closed-loop system from monitoring to warning and decision-making, providing full lifecycle health management support for boiler equipment.

Yingrun Group stated that it will continue to optimize the boiler water quality monitoring system in the future, combining AI prediction algorithms with 5G IoT technology to further enhance the ability to predict water quality anomalies and promote the development of the energy industry towards "unmanned operation and intelligent decision-making". This cooperation not only creates direct economic benefits for Pubai Thermal Power Company, but also highlights the profound significance of technology empowering traditional industries - through intelligent upgrading, the value of every drop of water can be released.
