摘　　要：针对目前国内外电站选用以V_2O_5为活性物质的SCR脱硝催化剂情况,进一步比较了蜂窝式、板式和波纹板式催化剂各自的特点,对蜂窝式脱硝催化剂的特性及对引起其变化的反应温度、烟气流速、氨的加入量和氨氮比以及飞灰的含量等影响因素进行了分析和讨论,并对蜂窝式脱硝催化剂的应用和在使用过程中出现的问题进行了阐述,为今后蜂窝式脱硝催化剂在燃煤电厂的应用提供了理论基础。Aiming at SCR deNOx catalyst of V2O5 active substance chosen by the current domestic and foreign power stations, the characteristics of honeycomb, plate and corrugated plate catalysts are compared. Moreover, the characteristics and effects of honeycomb deNOx catalyst, such as temperature, flue gas flowing rate, ammonia amount, ammonia-nitrogen ratio and the fly ash etc, are analyzed and discussed. The research provids a theoretical basis for the application of honeycomb deNOx catalyst in the coal-fired power plants hence.
