During the operation of the SCR system, the overall NOx reduction efficiency will gradually decrease over time due to imbalances in the distribution of NH3 injection and the formation of sulfate and bisulfate salts resulting from sulfur content in the fuel and catalyst degradation. Therefore, periodic checks of the overall system efficiency are necessary to prolong the catalyst lifespan, optimize operation, and avoid waste of reducing agent.
Additionally, assessing the efficiency of the SCR system is crucial during catalyst replacement at plants. The results of efficiency checks serve as important criteria for project completion acceptance.
With specialized equipment capable of meeting the needs of most modern plants, Chugai Technos has conducted SCR performance test of numerous thermal power plants in Vietnam, including Formosa Dong Nai, Mong Duong 2, Vinh Tan 2, and Duyen Hai 1.
If you need to test the performance of the SCR system to confirm NOx removal efficiency, NH3 slip concentration, NOx outlet concentration, please call the Hotline: 0909-714-566 or leave your information HERE for Chugai Technos to promptly contact you to answer inquiries and provide support.
