Coal Pulverizer Pall Corporation

Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner. Coal that has not been pulverized into fine enough particles cannot

Improving Coal Pulverizer Performance and Reliability

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

coal pulverizer or mill systems. The studies showed that there is an emergence of low rank, high reactive coals as a base fuel for power plants which is resulting in an increase in pulverizer system fires. Also, the EPRI study concluded that reducing the frequency of fires would reduce the risk of coal dust explosions. Unfor- tunately, less than 15 percent of the power plants have adequate
