Low-tech coal water slurry, produced from coal preparation plant pond impoundments, has the potential to provide nearby coal-fired electric utility power plants with a low cost fuel. It also can be used as a low cost nitrogen oxides reduction technique. The CWS may be fired in all types of electric coal-fired utility boilers using the co-firing or reburning technique. The staged combustor approach for firing pond fines allows for the removal of sulfur from the parent coal and the CWS being co-fired. It can also fire high ash coal fines and reduces NOx and particulate emissions significantly. The efficacy for a specific power plant to use coal recovered from preparation plant impoundments will be driven primarily by the cost of the delivered fuel from these ponds. However, in addition to cost savings considerations, by using any of the techniques described in this paper the electric utility industry is provided with low cost options for reducing NOx emissions.
