摘要
介绍了某厂2×1 000 MW超超临界机组投产后通过对传统的氧量控制及二次配风方式进行优化,大幅度降低了炉膛出口NOx排放量和风烟系统电耗。同时,还将试验所得的优化参数以函数曲线的形式应用于DCS中,实现了锅炉配风的精细化控制。
This paper introduces the results that the NOx emission in the boiler export and the power consumption of the air and gas system were reduced greatly by adjusting the oxygen volume and the second air distribution of the boiler of 2×1 000 MW ultra-super-critical units in Pinghai Power Plant？ The results realize the meticulous control of the second air distribution by using the curvilinear function of optimized parameter from the experiment in DCS system.
