[0042] Project overview: Transformation of SCR denitrification ultra-low emission project, transformation of 2×600MW coal-fired units, entrance NO X Concentration 400mg / Nm 3 , the original design efficiency is 80%, requiring denitrification outlet NO X Concentration≤50mg / Nm 3 , Ammonia escape ≤ 3ppm, SO 2 / SO 3 Conversion rate ≤ 1.5%.
[0043] Arrangement: Double reactors, conventional 2+1 arrangement, two layers of honeycomb catalysts are initially installed, and the conventional design method is adopted, and a commonly used circular vortex mixing device is installed above the ammonia injection grid.
[0044] After it was put into operation, problems were found: two layers of catalysts were initially installed, the design efficiency was 80%, and the performance was up to standard. The maintenance cycle of the air preheater was controlled at about 9 months. At the end of 2014, a spare layer of catalysts was added to improve the efficiency, and NOx was required to be denitr...
