چکیده انگلیسی
Using waste fly ash for mercury capture applications is an attractive, low-cost option for power plants. In this paper, the influence of nitric oxide (NO) on the mercury adsorption characteristics of HBr modified fly ash in an entrained-flow reactor was investigated using continuous monitoring and thermal decomposition methods. The results show that the adsorption efficiency of mercury by HBr modified fly ash was significantly enhanced when NO was added to the flue gas. Additionally, the rate of change of mercury concentration in the flue gas was increased due to increasing NO. The mercury adsorbed by HBr modified fly ash, in the entrained-flow reactor, exists primarily in two forms, HgBr2 and HgO. In the experiments of mercury adsorption with HBr modified fly ash on the entrained-flow reactor, NO mainly augmented the generation of HgBr2.
