Xinjiang Huadong Group Successfully Applies a New Type of Zirconia Oxygen Analyzer: Helping to Set a New Benchmark for Energy Conservation and Emission Reduction in the Thermal Power Industry

Customer Profile
Xinjiang Huadong Group is a major thermal power generation enterprise in Xinjiang, undertaking the core task of regional power supply. As a practitioner of the national "dual carbon" strategy, the Group has always been committed to improving the efficiency of coal-fired units and reducing pollutant emissions through technological innovation. However, in the boiler combustion optimization process, the instability and frequent maintenance of the original oxygen monitoring equipment have become bottlenecks restricting efficiency improvements.


Challenges: Pain Points of Traditional Equipment
In thermal power generation, the oxygen concentration monitoring of boiler combustion is directly related to combustion efficiency and environmental protection indicators. The original oxygen analyzer of a power plant in Xinjiang Huadong had the following problems:

Large Data Fluctuations Affected by flue gas dust and high-temperature environments, the measured values frequently drift, leading to lagging adjustment of the automatic control system;

High Maintenance Costs Monthly shutdown calibration is required, the sensor life is short, and the annual cost of spare parts replacement exceeds 200,000 yuan;

Energy Efficiency Loss Oxygen control deviations caused the boiler thermal efficiency to decrease by about 0.8%, and the annual coal consumption increased by thousands of tons.

"The original equipment cannot meet the needs of refined management, and a high-stability, low-maintenance solution is urgently needed." said the technical person in charge of Xinjiang Huadong.


Solution: High-Performance Zirconia Oxygen Analyzer
In response to customer pain points, our company customized the TFYHG® 5100 series zirconia oxygen analyzer ,the core technical advantages include:

Triple Anti-Interference Design Using self-developed high-temperature filtering modules and reference gas compensation technology, effectively coping with flue gas fluctuations, and achieving measurement accuracy of ±0.5%;

Ultra-Long Life Sensor The corrosion resistance of the new composite ceramic zirconium tube is increased by 3 times, and the calibration cycle is extended to 6 months;

Intelligent Diagnosis System Built-in AI algorithm for real-time monitoring of probe status, early warning of faults, and reduction of unplanned downtime risk.

During project implementation, the technical team was on-site throughout the process, completing the replacement of old equipment and system debugging within 72 hours, and conducting special training for maintenance personnel to ensure seamless connection.


Results: Breakthrough in Economic and Environmental Benefits
Since the equipment was put into operation, significant results have been achieved:

Improved Combustion Efficiency The oxygen control error has been reduced to within 0.3%, the boiler thermal efficiency has increased by 1.2%, and the annual saving of standard coal exceeds 5,000 tons;

Reduced Maintenance Costs Annual maintenance frequency reduced by 80%, spare parts expenditure reduced by 65%;

Emission Reduction Compliance The concentration of nitrogen oxides emissions is stably below 50 mg/Nm³, helping the power plant pass environmental protection assessment.

"This is one of our most successful technical transformation cases in recent years." feedback from the Xinjiang Huadong project team, "The new equipment not only provides accurate data, but its self-diagnosis function greatly reduces the maintenance pressure and provides reliable support for the construction of a smart power plant."


Industry Demonstration Significance
The successful implementation of this project has provided a benchmark solution for oxygen monitoring in high-dust and high-humidity environments. Currently, Xinjiang Huadong has promoted this product to three other units and plans to include it in the Group's green technical transformation recommendation list. In the future, the two parties will carry out in-depth cooperation in the field of combustion optimization big data analysis, jointly exploring the path of low-carbon transformation of thermal power.


Conclusion
Empowering the upgrading of traditional energy with technological innovation is the only way under the "dual carbon" goal. We look forward to working with more partners to promote the greening of industry with precise measurement technology and contribute to global sustainable development.

EXNFZRO®2 Explosion-Proof Zirconia Oxygen Analyzer Zirconia Analyzer


EXNFZRO®2 Explosion-proof Zirconia Oxygen Analyzer Significance of Measuring Oxygen Content with Zirconia Analyzer Flue gas oxygen content is one of the important monitoring parameters for boiler operation and an important basis for reflecting the completeness of combustion equipment and boiler operation. Its value is related to factors such as boiler structure, type and nature of fuel, boiler load, operating air supply conditions, and equipment sealing conditions. The smaller the oxygen content, i.e., the smaller the excess air coefficient, the more it indicates increased heat loss due to incomplete chemical combustion and mechanical incomplete combustion; the larger the oxygen content, i.e., the larger the excess air coefficient, the more it indicates excessive air supply. Excess air causes a drop in furnace temperature, which not only affects combustion but also carries away a large amount of heat and dust, increasing the calculated concentration of pollutant emissions. At the same time, a large air volume also increases the power consumption of flue gas exhaust. Controlling flue gas oxygen content is very important for controlling the combustion process and achieving safe, efficient, and low-pollution emissions. Application Scope The zirconia oxygen analyzer is an instrument used to monitor and control the oxygen concentration in combustion gases, boilers, and industrial furnaces. It is widely used in coal-fired power plants, gas boilers, waste incineration boilers, hazardous waste disposal incinerators, petrochemical cracking furnaces, metallurgical industry blast furnace hot blast stoves, oxygen-enriched combustion air pipelines, sintering furnaces, heating furnaces, heat treatment furnaces, metal material annealing furnaces, air separation oxygen production, food industry, cement kilns in the building materials industry, glass kilns, inert gas protection furnaces in the semiconductor industry, electrode material production furnaces in the lithium battery industry, and waste lithium battery recycling. It helps save energy and can also reduce CO2, SOX, and NOx emissions by controlling complete combustion, contributing to environmental protection, preventing global warming, and reducing air pollution.
