Reliable coal pulverizer performance is essential for sustained fullload operation of today's power plants. An effective pulverizer must be capable of handling a wide variety of coals and accommodating load swings in utility boilers as large as 1,300 MW.. BW's pulverizers, found at power stations throughout the world.
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 EPRI also identified oil contamination and excessive leakage as two areas where pulverizer drive train failures account for ...
