This study aims to explore the mechanism under which ash deposition propensity is improved by coal blending in a real modern boiler situation. In this paper Zhundong coal (ZD) from northwestern China known to have a heavy ash deposition problem in boilers was blended with Jincheng anthracite (JC) which has a high ash fusion temperature (AFT). The density composition of the coal
