Case Study: 2 × 1,030 MW Ultra-Clean Emission Rehabilitation Project
Source: Date: 15.06.23

CPI Yuanda Environmental Protection Engineering Co., Ltd completed an Ultra-Clean Emission Rehabilitation Project for the 2 × 1,030 MW units of Huaneng Nanjing Jinling Power Plant. The scope of works include addition of the two-phase rectifying device, the spray layer and the outlet pipe defogger as well as replacement of old defoggers. The 168-hour test run result shows that all technical indicators met the ultra-clean emission requirements, with the SO2 and dust concentration at outlets being 25 mg/m3 and 2.4 mg/m3 respectively and the WFGD dust removal efficiency exceeding 80%.

This project is among the first batch of SO2 and dust ultra-clean emission demonstration projects designated by the National Energy Administration and Huaneng Group, and is so far the largest and first operational ultra-clean emission project for 1,000 MW-class units in China.
