烟气循环流化床同时脱硫脱氮试验研究

该文应用自主开发的高活性吸收剂，在自行设计的烟气循环流化床上进行了同时脱硫脱氮试验研究，探讨了影响高活性收剂脱除效率的诸因素，确定了工况条件。当Ca／(S N)比为1．1时，SO2脱除效率达92．3％，NOx脱除效率达60．8％。在试验的基础上，探讨了烟气循环流化床同时脱硫脱氮的机理，研究结果对工业应用有重要的参考价值，该新的烟气循环流化床同时脱硫脱氮技术在国内外将有广阔的应用前景。该项研究未见报道。

TESTING STUDY ON SIMULTANEOUS REMOVAL SO2 AND NOx BY FLUE GAS CIRCULATING FLUIDIZED BED

The test of simultaneous desulfurization and denitrification was carried out in this paper by using the self-developed highly active absorbent at the self-designed flue gas Circulating Fluidized Bed (CFB), the factors influencing for the removal efficiency of the highly active absorbent were studied,and the working conditions were established. The removal efficiencies of 92.3%, 60.8% for SO2 and NOX were achieved at a Ca/(S+N) molar ratio 1.1 , The mechanism of Simultaneous removal for SO2 and NOx based on CFB was investigated on the base of tests. The testing results can offer valuable references for industrial application. The foreground of application will be vast in china and in the world with a new technology of simultaneous removal SO2 and NOx based on Flue Gas Circulating Fluidized Bed. This study has not been reported.
