Recently, the 1# desulfurization absorber of 2 × 140 t/h boilers flue gas desulfurization and dust removal ultra-low emission project of Ruian Huafeng Thermal Power Co., Ltd., which contracted by JNG China, has successfully completed the 168 hours reliable test.

The construction of the project was completed on December 8th, 2018. The flue gas of 1# boiler was introduced on February 20th, 2019. The 168 hours reliable test of 1# absorber was started on March 9th, and completed on March 16th. On March 20th, 1# absorber completed the by-product discharging for the first time, and the owner approved and signed for approval on March 22nd. During the reliable test, the FGD unit operated stably, and each performance index reached or exceeded the design index. The project adopts JNG’s Ultrasound-enhanced SO2 and Particulate Control Technology (USPAC). The flue gas treatment volume of 1# absorber is 150,000 Nm3/h, and the inlet SO2 is less than 2,500 mg/Nm3. Under the design condition, the SO2 emission concentration is no more than 35 mg/Nm3, ammonia slip concentration is no more than 2 mg/Nm3, and dust concentration is no more than 5 mg/Nm3, which meets the ultra-low emission standard.

This project is the second cooperation between JNG and Huafeng Group. Our first-class technology, efficient and rigorous style have been recognized and praised by the owners. In the future, we will, as always, do a good job in after-sales service and contribute our modest contribution to the environmental cause of China.
