| 摘 要： | 东方锅炉对某电厂加拿大B＆W公司设计制造的2号锅炉进行了以降低氮氧化物排放为目标的改造。通过更换新型低氮燃烧器和增加燃尽风喷口，使氮氧化物的排放值明显下降。通过对受热面调整，解决了改造引起的过热器减温水流量增大的问题。经过燃烧调整，锅炉热效率比燃烧器改造前基准试验值略有提高，过热器减温水流量也得到了控制。

| Abstract: | In order to decrease NOx emission,the burner(wall type) designed by Canada B&W Inc.used in Beilun Power Generation Co.Ltd.No.2 is retrofitted by Dongfang Boiler.Through replacing and utilizing new type OPCC burner with over-fired air(OFA),the NOx emission has been reduced greatly.By adjusting heat surface arrangement,the problem of desuperheater spray flow increasing is solved.After combustion regulation,the boiler efficiency is improved accordingly. |
