In the present research work, volatile matter, influences of reaction temperature and particle size on combustion performance were investigated. Important results were obtained by experimental researches. Ignition point of anthracite coal/bituminous coal blends decreased with volatile matter in blend and combustion was improved. Burnout of coal blends decreased as a function of particle size. However, similar effects were gained when particle size less than 0.074mm accounted for 70%, 60% and 50%, respectively. By contrast, the ratio of 50% was a better choice for good effect and low cost.
