Abstract	The combustion process of a 1000 MW ultra supercritical dual circle boiler was numerically studied with Realizable k-ε model. The influence of the boiler NO distribution was studied when burner nozzle air velocity and structure change, NO distribution was compared between the original and being improved structure. The numerical simulation results show as follows, two opposite oval rotary temperature and flow field are formed in the furnace during the combustion process, When shape and layout of the burner nozzle are different, large change about NO distribution in the furnace. NO emissions change small in every conditions. Increasing the size of pollen tube nozzle can reduce NO emissions, which is the best improvement programe and provide some theoretical basis for the burner design and operation.
