Abstract: Abstract:The drytype lowpollution burner and the low NOx combustion technology were introduced. In the drytype lowpollution burner, which is installed on the 9E gas turbine, the conventional diffusion combustion mode was discarded and replaced by homogeneous phase premixed turbulent flame propagation combustion mode. For the nature gasfired unit, when the unit load is greater than 50% of rated load, the mass concentration of its NOx emission can be controlled below 37mg/m3, which is lower than 50mg/m3, which is the limit value specified in state standard.
