摘要
为研究掺烧对机组NOx排放和锅炉效率的影响,对某电厂600 MW超临界机组进行热态试验。分析了煤质特性、煤的组合方式、配风控制对机组NOx排放和锅炉效率的影响,阐述了不同工况NOx的排放规律,为电力生产企业优化燃烧过程,降低燃料成本和污染物排放提供依据。
This paper presents experimental investigations into the NOx formation behaviors and thermal efficiency of coal blending combustion in one 600 MW boiler. The influence of coal property, combination method and air distribution control strategy on thermal efficiency and the NOx emission of the boiler is investigated. Based on the test results, emission behaviors of NOx under various operating conditions are analyzed. This work can provide valuable reference for similar power stations to optimize combustion and reduce pollutant emission.
