The flue gas from anthracite combustion went to react with char in a double-pipe fixed-bed test system to simulate real atmosphere of anthracite combustion, with which the influencing factors of anthracite-char activities to NO reduction were investigated. Anthracite-char can observably reduce NO, and temperature increase is beneficial to the char activities of NO reduction;for particle size of char, the smallest one is not the best one, and there is an optimum size to NO reduction;specific surface area of anthracite-char is the key factor in influencing the char activities;volume ratio of CO and CO2can represent anthracite-char activities to NO reduction, and the smaller the value is, the stronger the activities are.
