600MW亚临界机组锅炉优化燃烧试验研究

Study on Optimal Combustion Test of 600MW Sub-critical Unit Boiler

介绍了某电厂600MW亚临界机组锅炉燃烧调整试验。对制粉系统进行了优化调整;分析了不同负荷下氧量的变化对锅炉效率的影响,并给出了最佳氧量值;在600MW负荷下进行了二次风箱压力对锅炉效率影响试验,并做出了二次风箱压力对锅炉效率影响曲线;分析了锅炉NOx排放特性。

The combustion adjust ment test of 600MW sub-critical unit boiler in a power plant was introduced, Milling system optimal adjustment was carried out. The impacts of oxygen＇ s change under different loads on the efficiency of the boiler was analysed, and the best value of oxygen was also given. We also carried out tests to identify the impacts of secondary bellows pressure on the boiler＇ s efficiency under 600MW load and made the curve of second bellows pressure on the change of boiler＇ s efficiency and the NOx emission characteristics of the boiler was analysed at last.
