Dec 31, 2018 Georgia Power's Plant Scherer is one of the largest coal-fired thermoelectric power-production facilities in the United States. It is a 3,520,000-kilowatt coal-fired facility that provides electricity for Georgia. As this diagram shows, the plant operates on the same principles as other fossil-fueled electric generating plants—it burns coal.
Typical maintenance costs and intervals for each pulverizer gearbox were as follows Oil changes required every 12 months at a cost of $5,000 in material and labor and $20,000 to $50,000 in lost electrical production, typical of most coal-fired power generation units of this timeframe. This particular plant had 13 of these coal pulverizers.
Coal Pulverizers. RPM Associates manufactures and rebuilds coal pulverizer parts for Combustion Engineering, Foster Wheeler, Babcock Wilcox, and Alstom bowl mills. Our mill body wear liners, deflector liners, journal liners, and pulverizer rolls are engineered to offer the longest wear life with the lowest risk of catastrophic failure.
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 pulverizer-related problems.1 EPRI also identified oil contamination and excessive leakage as two.
Types of EGUs and not specific to coal power. Descriptions of major coal-unique components are presented in the next section.
