摘要
A system and method for salt operation of a urea-SCR system at low temperatures (200-350 ° C.) in the presence of high SOx content flue gas is described. The method includes introducing a solution of urea and at least one NO2 forming compound, preferably an alkaline earth metal nitrate, into the flue gas stream before the flue gas stream contacts the SCR catalyst.
