Technology Study On Circulating Fluidized Bed For Simultaneous Desulfurization And Denitrification Of Flue Gas

The highly reactive sorbent with oxidization was prepared from fly ash,lime and additive .We find the additive NaClO₂ which have the uppermost denitrification efficiency by the fixture bed experiment.And then we have the simultaneous desulfurization and denitrification experiment on the duct injection, we study additive content,temperature,humidity and Ca/(S+N) which have effect on the efficiency of desulfurization and denitrification, and find the optimal technologic condition. We have the primary test on the circulating fluidized bed with the technologic condition, and find the removal efficiency is 93.6% and 68.8% for SO₂ and NOx respectively. The next is primary dynamics study on NO absorption with liquid NaClO₂, acquire the reaction order of NaClO₂ and NO and the activation energy, and study the effect of kinds of parameter on the absorption rate. The study work offer important basic data to industrial application of simultaneous removal SO2 and NOx based on Flue Gas Circulating Fluidized Bed.
