摘要:

针对我国燃煤电厂高灰烟气开发的新型高强脱硝催化剂,在某电厂2×600 MW机组脱硝系统中得到了应用。介绍了该燃煤电厂的脱硝系统特点和烟气条件,高灰烟气脱硝催化剂的设计与选型、脱硝工程验收情况和运行18个月后催化剂的各项性能。结果表明:在高灰烟气条件下,脱硝催化剂正常运行3个月后,使用状况正常,初期脱硝效率显著,达到83.9%,净烟气NOx质量浓度达到73.7 mg/m3,氨逃逸量、SO2/SO3转化率、系统压力损失等参数均优于设计值;正常使用18个月后,脱硝催化剂各项性能正常,耐磨损性能优异。

Abstract:

The de-NOx catalyst developed for the high-dust flue gas in power plant was successfully applied in denitration system for 2×600 MW units in a power plant. The characteristics of denitration system and the conditions of flue gas in this power plant were introduced, as well as the design and selection of the de-NOx catalyst, the acceptance of denitration engineering and the changes of various performance parameters of de-NOx catalyst used for 18 months. The results show that the application of de-NOx catalyst developed for the high-dust flue gas for 3 months is very well. The denitration efficiency which reaches about 83.9% is significant, and the NOx concentration is reduced to about 73.7 mg/m3 in the flue gas. Simultaneously, the amount of ammonia slip, SO2/SO3 conversion rate, and the loss of system pressure are better than the design value. In addition, after used in the high-dust flue gas for 18 months, various performance of the de-NOx catalyst is normal, and wear resistance is excellent.

Key words: denitration in power plant, selective catalytic reduction catalyst, high-dust flue gas
