Based on one dimensional model, this paper reports a new characterization & measurement method to determine the gas diffusion property through the ash layer on coal particle during the combustion process. Experimental results of gas diffusion through coal ash layer for the ten typical Chinese coals show that the proposed characterization & measurement method is of great importance to the design, operation and modelling of low grade coal fired-fluidized bed combustion boilers.
