Influence of unit loading on operation of SCR flue gas denitrification system |
| |
| Abstract: | Based on the analysis of performance detected data in SCR flue gas denitrification system,the importance of controlling the ammonia slip rate of SCR system exit strictly and flushing the air preheater regularly were described.The suggestions were given to adjust the flue gas temperature by adding small bypass to ensure normal running on the lower unit loading status in SCR systems of some coal-fired power plants. |
