Application and research of left and right Sway-OFA technology on coal-opposed firing boiler
The author proposes a horizontal swing OFA technology and applies it to 350 MW and 660 MW supercritical coal powder combustion boilers.The research results show that,under the premise of not increasing NOx emissions,the swing of the OFA can significantly reduce CO emissions and solve the uneven distribution of conventional CO near the side wall water-cooled wall,which is high and low in the middle.At the same time,it reduces the deviation of oxygen content at the outlet of the econo-mizer and also alleviates the phenomenon of individual wall temperature overheating.This technology is easy to operate,reliable to operate,and can effectively improve the uniformity of flue gas at the furnace outlet.
