Influence of Denitrification System High Ammonia Escape Rate on Air Preheater and Prevention Measures
Power system changes in operation mode after the denitration system installation in thermal power plants.This paper analyzes the causes of the ammonia injection grid wearing,high ammonia escape rate,the cold end ammonium hydrogen sulfate corrosion and ash deposit in the air preheaters.Then it presents prevention measures to adjust the operation modes,control ammonia escape rate and the cold end ammonium hydrogen sulfate corrosion and ash deposit in the air preheaters,with a view to reducing the unplanned outages of generating units.
