  • Improving Coal Pulverizer Performance And Reliability

    Coal utilization - Coal utilization - Coal combustion The most common and important use of coal is in combustion, in which heat is generated to produce steam, which in turn powers the turbines that produce electricity. Combustion for electricity generation by utilities is the end use for 86 percent of the coal mined in the United States. The main chemical reactions that contribute to heat.Introduction. Power generation industry studies have shown that coal pulverizers are an area where improved equipment reliability is badly needed. The Electric Research Institute (EPRI) has determined that 1 of plant availability is lost on average due to pulverizerrelated problems.1 EPRI also identified oil contamination and excessive leakage as two areas where pulverizer drive train.
