Abstract

Taking the SCR flue gas denitrification system of a 1000MW coal-fired boiler in a power plant as the research object, through the coordinated test of the temperature field, flue gas field, NOx concentration field and NH3 concentration field at the entrance and exit of SCR, taking into account the influence of temperature, flow field and concentration field on denitrification reaction comprehensively, the ammonia injection optimization adjustment test was carried out under 900MW load, and the ammonia nitrogen molar ratio distribution at the entrance of SCR was optimized to improve the denitrification reaction. The uniformity of NOx distribution at SCR outlet was improved, and the ammonia escape concentration was reduced. The validation tests were carried out under 750 MW and 500 MW loads, and the NOx concentration distribution and ammonia escape concentration at SCR outlet were tested.
