The results from the field tests positively impacts pulverized coal power plants that burn low rank high volatile content coals (such as Powder River Basin coal). These plants can potentially reduce inplant load by grinding the coal less (without impacting plant performance on emissions and efficiency) and thereby, increasing their marketability.
