The pure effects of various important factors, i.e., the initial oxygen concentration, flame temperature and flame pattern on the NOx formation during oxy-coal combustion are investigated. As a result, we show the flame pattern changes from a detached flame to an attached flame with the increase in flame temperature. The single particle model for estimating NO_x emission level is applicable to the detached flame pattern. This implies that in the case of the detached flame, pulverized coal burns with a structure of premixed flame.
