由于燃料中含氮率高,以致难以减少燃煤锅炉中的氮氧化物含量(NOx)。现在,于正在运行的锅炉上采用低NOx煤粉燃烧器(双重调风器燃烧器),并应用通常的二级燃烧方式,成功地使NOx浓度降低一半(约降低47%)。
Due to the high nitrogen content in the fuel, it is difficult to reduce the nitrogen oxide content (NOx) in the coal fired boiler. Low NOx pulverized coal burners (dual dimmer burners) are now used on running boilers and are successfully halved in NOx (about 47% reduction) using typical secondary combustion.
