Ash accumulation in SCR reactor of thermal power plant is an important factor affecting denitration performance and safe operation.Aiming at the ash accumulation in denitration reactor during the operation of thermal power plant,the distribution characteristics of fly ash inside the reactor were studied by numerical simulation.The concentration distribution of flue gas and fly ash inside the reactor was optimized and adjusted by adding the number of diversion plates at the third corner through flow field optimization,and the non-uniformity of flow field and fly ash concentration field in front of catalyst layer was reduced.
