چکیده انگلیسی
To reveal the microscopic characteristics of the post-explosion coal dust samples, coal dust explosion tests were performed in a 20Â L spherical vessel. The explosion characteristic parameters, such as the maximum pressure (Pmax), the maximum rate of pressure rise ((dP/dt)max), ignition time (t) and the deflagration index (KSt) were recorded. Meanwhile, the post-explosion dust samples were collected and analyzed. The research efforts include particle size distribution analysis, SEM analysis and FTIR analysis of dust samples before and after the explosion. The particle size range of post-explosion dust samples became wider according to the mass percent analysis. The microscopic appearance of samples in same particle size range showed some similarity. The porous structure of dust samples was observed by improving the SEM magnification. The chemical structure of dust samples before and after explosion was analyzed by FTIR.
