The blockage of pulverized fuel (PF) conveying pipes on a coalfired power plant is a hazard accident. An indepth understanding of the factors that cause PF pipe blockage provides operators with prior knowledge to avoid such accidents. Two representative primary air pipe blockage events are observed on two commercial boilers, respectively.

Coal impacts: water pollution. When you burn charcoal in your grill at home, ash is leftover. The same is true for coalfired power plants, which produce more than 100 million tons of coal ash every year. More than half of that waste ends up in ponds, lakes, landfills, and other sites where, over time, it can contaminate waterways and drinking water supplies.

coalfired capacity peaked at 318 gigawatts (GW) in 2011 and has been declining since then because many plants retired or switched to other fuels and few new coalfired plants came online. By the end of 2019, coalgenerating capacity totaled 229 GW. The coal fleet's rate of operation, or utilization, has also decreased.
