Kraft lignin as a fuel for the rotary lime kiln

The lignin fuel was found to be more efficient at supplying heat to the solids bed when compared to natural gas and this was reflected in the axial calcination profiles. It was concluded that dry lignin could be an acceptable fuel in either partial or complete replacement of natural gas, without penalty in lime quality or kiln productivity.
