600MW机组锅炉二次风挡板的控制与运行特点分析

Control and Operation Characteristics Analysis of Secondary Air Damper of 600 MW Unit Boiler

根据锅炉燃烧器的设计特点,二次风挡板分为辅助风挡板、周界风挡板、顶部燃尽风挡板和油枪层风门挡板。通过对燃烧器二次风挡板控制的分析,可以更好地了解二次风挡板在锅炉的燃烧调整过程中的调节的重要意义和热控DCS逻辑,提高机组的控制水平,更好的维持机组安全、经济、稳定运行。

According to the design features of the boiler combustion,secondary air baffle according to their works were divided into secondary air baffle,baffle perimeter wind,burn the top layer of the wind baffle and oil damper baffle gun.By analysis of burner secondary air damper,It＇s more better to understanding of the secondary air baffle in the boiler combustion adjustment process in the importance of regulation to understand the DCS thermal control logic,and to improve the control unit level,can better.
