%X Mathematical simulation and experimental study for the influence of pulverized coal size on NO_x emission performance in a bench scale furnace have been done. The results show that there exists a critical diameter (dc). If ddc, the NO_x concentration reduces with the increase of the pulverized coal size. The concentration of NO_x is reduced for superfine pulverized coal whether in the oxidative circumstance or in the reductive circumstance. The quantity of NO_x released from superfine pulverized coal decreased obviously for lignite, but decreased little in some sort for anthracite. Overall reasonable agreement between the simulating and experimental results for NO_x release behavior is obtained.
