| Abstract: | The overall process of the complex chemical reaction in the coal combustion can be learned by studying the changes of SPFD.The 2-value digital image and matrix about the surface pore were studied by applying Matlab to analyze the SEM photographs of char samples during combustion.In accordance of the property of 2-value digital image,the principle and method of calculating SPFD adopting box-counting dimension were minutely discussed basing on the fractal theory.This article provides a kind of calculating method for the study of the surface structure changing in char combustion process. |
