Coal-fired power stations rely on storing coal in large bunkers or silos. Over time, changes in the type and quality of coal can lead to poor flow during discharge, creating production inefficiencies and significantly reducing storage capacity. Manual intervention is frequently used to promote flow; however, this is a hazardous process for operators and fails […]

Anyone operating a coal-fired power plant has faced the challenge of keeping coal-handling equipment free of blockages and plugging. Not only do material flow problems interrupt smooth plant operations, but they also require dirty, sometimes dangerous, and often unscheduled maintenance work. As in many other industries, remote-controlled tools can help solve this problem. Bulk material […]
