Last spring I had a final delivery of rice coal that was very dry and dusty. The two deliveries up to that point were moist and hardly created any black dust when moving it from my bin to the hopper. I know others must be doing something about this before the buring season starts... I did some searching and found that water can be used and maybe mixed with oil. How long does just watering the coal last before it would need to be watered again... If someone already has this figured out I would appreciate the knowledge of how you deal with the dry coal before you bring it into your house and put up plumes of black clouds pouring it into the hopper. I have about 1.5 tons in my bin.
