摘要：

The 1.1MW burner in a tube furnace of a petrochemical company takes non-premixed fuel-staging as the low-NOx strategy. The total flow rates of the fuel-gas and air remain the same, however, operating conditions change with different primary/secondary fuel-gas flow rates, whose surrounding flow fields are simulated by the CFD software FLUENT. The outlet fractions of pollutant NO and CO are then obtained, as well as the uniformity of heat transfer from the mixed furnace gas to the tube, thus corresponding to different operating conditions. Finally, this study may help in the selection of practical operating condition.
