| Abstract: | Taking SCR deNOx installations for 600MW thermoelectric generating set as study object,CFD software was used to complete the building models,division of grid,choosing the mathematical model,setting boundary conditions,and simulation work;at last it was obtained the results of SCR deNOx system velocity distribution and Cv value,pressure loss,distribution and escaping concentration of NH3.Results indicated that SCR deNOx system velocity was distributed evenly and the deviations in line could meet design requirements,NH3 was mixed with flue gas evenly,ammonia escaping concentration was low. |
