Abstract
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 CO2 can represent anthracite-char activities to NO reduction,and the smaller the value is,the stronger the activities are.
