To reduce NOx generation of the boiler in power plant is the important aspect of reducing NOx emission. Against a opposed firing boiler, it adjusted the amount of oxygen, the way of secondary air, the way of mill combination, OFA rate, coal fineness, etc, and caused NOx generation decreased about 22%, and had small influence on the economy and safety of boiler. The result showed that reducing the oxygen amount of the main combustion zone is the key to reduce NOx generation.
