Recently，The Academy bc game casino and Technology passes technical research，Innovative on-site adjustment test method，Successfully solved the industry problem of air preheater blockage in Cathay Pacific Boiler No. 11。After continuous operation on site for 20 days，The uneven NOx distribution in the outlet flue of the SCR system has been significantly improved，Ammonia consumption is reduced by about 16% under the same working conditions，Effectively guarantees the safe and economical operation of the unit。At the same time，It also marks a breakthrough in the work of the boiler air and smoke system resistance increase control technical research team established by Jiantou Energy in June last year。
According to the unified deployment of Jiantou Energy，The Academy bc game casino conducted an energy consumption diagnostic test on Cathay Pacific’s Unit 11 in November 2022。Uneven distribution of NOx in the outlet flue of the SCR system for test exposure、The maximum pressure difference between the front and rear flue gas sides of the air preheater reaches 3.1kPa，The serious congestion issue is the focus，The Academy of Energy Science and Technology concentrates its professional forces to carry out technical research，Creatively proposed the SCR entrance and exit joint debugging test method for uneven flue gas flow field。Early February 2023，With the strong support of leaders at all levels of Cathay Pacific，The Academy bc game casino will apply the research results on site，Conducted on-site ammonia spray adjustment test on Unit 11。After test adjustment，Boiler SCR A、The relative standard deviation (CV value) of the NOx concentration distribution at the B-side outlet is from 50.40% and 28.07% reduced to 19.65% and 11.07%，The uniformity of NOx distribution at the denitrification outlet section has been significantly improved。Discovered after 20 days of continuous operation on site，The air preheater blockage problem of Unit 11 has been significantly alleviated，Ammonia consumption is reduced by about 16% under the same working conditions。
The Academy bc game casino will continue to increase its efforts in technological research，Concentrate on solving the common focus issues in the energy consumption diagnostic test of each factory，And promote effective experience to other units，Recreate the highlights of improving quality and efficiency，Provide strong technical support for the safe, stable and economic operation of system enterprise units。
