ANNOTATION: A specific size of whole tree chip was needed to co-mill wood chips with coal. The specifications are stringent because chips must be mixed with coal, as opposed to a co-firing process. In a partnership involving several entities, a trial was conducted to determine if wood chips could be created in a one-step in-woods process that would meet the stringent requirements of the power plant. Precision-Husky, of Leeds, Alabama, volunteered to work with the partnership to manufacture a machine that would create the chips to the stringent specifications needed.
