摘　　要：为了降低污染排放,对某电站300 MW锅炉WR低NOX燃烧器进行了试验研究。结果表明,电站锅炉应用WR燃烧器后,NOX平均排放浓度为341 mg/Nm3,达到低NOX燃烧要求,并且具有高的锅炉效率。NO_X is one of the main pollutions of atmosphere pollution.Low NO_X burner is the important means of reducing NO_Xin flue gas and lower environmental pollution.It is adopted generally in boiler built and rebuilt.Widely regulating burner(WR) is an advanced low NO_X burner.The experimental study on low NO_X combustion technology of WR burner of 300MW boiler was completed in order to reduce the emission.The result shows that the NO_X emission is 341 mg/Nm3 by using the WR burner and achieves the low NO_X combustion with high efficiency.It is the reference of the application of low NO_X combustion at power plant.
