Sawdust as fuel

I use one to heat my 3,000 sq ft house and the other to heat my kiln. During the day in the cold of the winter I fuel each stove with sawdust from my Mobile Dimension Sawmills, which are circle saws. Of course, the material is much coarser than one gets from band mills, therefore I would think that the explosiveness of the dust may be far less likely.
