Study on Stability and Reliability of NOx Ultra-low emission in Coal-fired Power Plants in China

摘要

Along with the rapid progress of flue gas ultra-low emission reconstruction in coal-fired power plants in recent years, the stability and reliability problems in the operation of the project have emerged, among which the denitrification problem is the most acute. Given the present situation of the NOx ultra-low emission in coal-fired power plants, several typical problems about stability and reliability have been analyzed and discussed, including flow fields uniformity, low load denitrification, in-line meter accuracy, catalyst life on the basis of extensive and thorough investigation. Relevant guidance and countermeasures are proposed to provide further reference for the following denitrification projects and operations.
