Power Plant Fly Ash - BJM Pumps

Nov 27, 2011· The Challenge The most challenging place for a pump at a coal-fired power plant is the hot fly-ash pit. Fly ash is a heavy and abrasive powder produced during the combustion of coal. Power plant operators recover fly ash from their combustion gas flues to remove particulate pollutants from air emissions, and they store fly ash in outdoor piles or pits.

How to Measure Flyash Levels - powermag.com

Measuring the level of flyash in your silos is not an easy task, in part because the flyash collected at one plant can be remarkably different from that collected at another plant, even if both fire the same coal. Such variability means that selecting the right instrument for your application is important.
