In order to explore the combustion characteristics when dual burners work together,the most widely used positive arrangement in the actual heating furnace is modeled,and its combustion conditions under different excess coefficients are simulated.The velocity distribution,temperature distribution and outlet NOx in the furnace are emphatically analyzed.The results show that when the double burners are arranged in the opposite direction,the gas ejected from the burners will stagger each other and enter the opposite burner side for combustion after meet-ing in the furnace center,and this feature is more obvious in the width direction,so the temperature field of the burners is distributed symmet-rically in the center,and the temperature difference in the height direction is smaller than that in the width direction.The change trend of NOx of dual burner and single burner with excess coefficient is the same,but the NOx generation of dual burner is 1.6 times greater than that of sin-gle burner.
