With blocked normal bypass, the seepage water found its way to the coal silos and created large clumps of icy coal that blocked the coal conveyors. Although freezing weather is not unusual at high-latitude power plants, the common methods to combat freezing of coal are mainly useful for open storage sites and above-ground …
Fortunately, there were no fatalities. Then, on February 10, 2017, a 40 year old coal silo failed at a plant in Tennessee, dumping 800 tons of coal. Once again, there were no fatalities. Both of these incidents have been attributed to failure of the cone-to-skirt weld on the large coal silos. These coal silo failures were unexpected and alarming.
Many coal-fired power stations built before 1980 were designed for handling relatively easy-handling lump coal. If your plant's bins, bunkers, and silos aren't up to dealing with today's ...
