A possible mitigation for the low grindability is less grinding, if the coal could be burned at a coarser grind without impacting power plant performance. The rank and volatility of the coal …
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 in-plant load by grinding the coal less (without impacting plant performance on emissions and efficiency) and thereby, increasing their marketability. 1.
Cost of electricity from existing coal plants. As of July, 2008, the average cost of coal supplied to existing coal plants in the United States was $2.09 per million BTU. At 34.3% efficiency for a typical coal plant, that translates to 2.08 cents per kilowatt hour for coal.

For coal-fired power plants, the response time of the coal mills is critical for the overall reaction time to changing demand. Flexible operation or load following requires that the output of the plant can be made to vary in accordance with demand and in accordance with allowable ramp rates.
The coal fired power plant converts energy in coal to electricity. The basic input into the system is the fuel that is coal. All other systems and equipment only aid in this conversion process.
beneficiated coal in thermal power plants, a study was instituted. Results of the study are encouraging in favor of using washed coal in thermal power plants. Cost of energy may become cheaper even for the pithead power plants if these use washed coal and utilize rejects in AFBC/CFBC boilers at the pithead.
Those first coal-fired plants (in Greensboro, N.C., and Greenville, S.C.) only supplemented the company’s use of hydroelectricity. In the 1920s, the growing demand for electricity began to outstrip the availability of hydroelectric generation.
