摘要
介绍了某电厂利用空气分级燃烧技术对420 t/h锅炉燃烧器进行的低NOx排放改造情况,对锅炉改造前、后的NOx排放浓度进行了对比分析。结果表明,对锅炉实施低NOx改造后,NOx排放浓度明显下降,但锅炉热效率亦有所降低。
The reformation for low NO emission of one 420 t/h boiler in thermal power plant was introduced detaily,in which air staged combustion technology was used to reduce the NOx concentration. Then the boiler performance before and after the reformation were compared. Results showed that the NOx emission was reduced obviously, but the boiler thermal efficiency was descended slightly.
