Experimental research on non-isothermal combustion characteristics and dynamics parameters of applied pulverized coal under preheating domestically is conducted with a thermo gravimetric balance. The combustion characteristic parameters such as ignition temperature, peak temperature at maximum weight loss rate, burnout temperature, general burn exponent(G), and maximum combustion rate are studied under different preheating temperatures of 423, 473, 523, 573, 623, 673, 723 and 773 K. The activation energy (E) and frequency factor (A) are also calculated. The results show that for pulverized coal in the North Area, during the preheating process, when temperature varies from 423 K to 773 K, ignition temperature decreases by 240 K mostly, peak temperature at maximum weight loss rate decreases by 263 K at most, maximum weight loss rate increases as 1.29 times, and G increases up to 29.8 times. It shows that there is lining fit result between E and ln A, which proves that the reaction could be regarded as first order reaction. The combustion process behaves greatly when preheating temperature is over 673 K for the pulverized coal.
