Flow field simulated research and practice of united denitration SCR system in coal fired power plant

Abstract

Abstract:

Abstract:The fluid flowing characteristics of united SCR denitration system was reseached. With the help of the numerical simulation and phasical cold state model test, the flue gas flow field, the vilocity and temperature distribution and the pressure loss of the SCR denitration system under different conditions were calculated and verified. The research result of flow field simulation was used to guide the optimal design of SCR denitration system, and the denitration system operated in optimal condition. The result in this paper can be used as reference for reformation of denitration system in aged power unit.
