| 摘 要： | 介绍了CFB锅炉性能试验情况，并结合性能试验分析了SNCR脱硝装置对CFB锅炉运行的影响。结果表明：CFB锅炉SNCR脱硝工艺的脱硝效率可以达到60%以上；氨逃逸浓度高会加速空气预热器积灰阻塞；烟气中的逃逸氨与SO3相互作用，极易在空气预热器低温段形成积垢，引起空气预热器阻力增加，但能降低二者在空气预热器出口的排放浓度。

| Abstract: | In this paper, the performance testing of a CFB boiler is introduced. And then through the testing, the impact of SNCR system on CFB boiler operation is analyzed. The results show that the deNOx efficiency of SNCR system can reach over 60%. High ammonia slip will accelerate the block of air preheater by fly ash. The interaction between the slipped ammonia and SO3 can cause fouling at the low-temperature end of the air preheater, which makes the resistance of the air preheater increase, but on the other hand it may lower the emission concentrations of ammonia slip and SO3. |
