| Abstract: | The key parts of a SCR denitrification reactor have very obvious impacts on pressure loss characteristics of the boiler and its auxiliary equipment. The effect of every key part on pressure loss was studied on a De-NOx reactor of a 1×300 MW coal-fired boiler unit by numerical simulation and experiments. The optimal design scheme was determined. The first key part was designed for two straight-art baffles. The second one was designed for the tooth profile of anti-grinding plate. The third one was designed for 2 straight-art-straight and 5 art-straight baffles and the fourth one was designed for rectifying layer (there are 45 rectifying units in a rectifying layer and 40 rectifying grids in each unit). The result of pressure loss shows that the most important key part is the second one and the minimal one is the fourth one in the SCR denitrification reactor. |
