EXPERIMENTAL STUDY OF THE EFFECT OF COAL PODWER GRANULARITY ON COMBUSTION CHARACTERISTICS BY THERMOGRAVIMETRY

摘要：

An experimental investigation on the combustion performance of the pulverized coals of eight different particle sizes, which are taken from Jinzhushan and Zhengzhou respectively is conducted by TG dynamic runs at 20℃/min in the temperature range 20～1000℃. After dealing with experimental data, the kinetics parameter E were obtained. The experimental investigation has proved that the maximum combustion rate occurs more early and ignites more early while the particle size of coal decreases, the ignition temperature and burnout temperature decrease. In addition, activation energy is decreased, the complex combustion characteristics index can be obviously improved, and the combustion property can be perfected, while the particle size of coal decreases.
