Blending Coal

The blending of PRB coal with lignite improves fuel quality and can reduce emissions. PRB coal is an inherently low-ash fuel with lower concentrations of sulfur compared to lignite. Blending PRB coal with lignite reduces the ash concentration, and slagging and fouling potentials are less than when blending PRB coal with most bituminous coals.
