Pulverized coal-fired boiler - Wikipedia
Pulverized coal power plants are divided into three categories: subcritical pulverized coal (SubCPC) plants, supercritical pulverized coal (SCPC) plants, and ultra-supercritical pulverized coal (USCPC) plants. The primary difference between the three types of pulverized coal boilers are the operating temperatures and pressures.
