  • Explosion protection for coal grinding plants What

    The coal mill is operated as an airswept mill and “blows” directly into the combustion zone of the steam boiler, via a pipeline connection In case of an explosion, normally as consequence of ignition within the mill chamber, there will be explosion propagation towards the boiler The combustion “cloud” will propagate to where it findsRaw coal is conveyed from the storehouse by a belt conveyer Then it is lifted to the entrance level of a vertical cylindrical mill by a bucket elevator, and an electromagnet is used to remove iron objects from the raw coal The raw coal is pulverized in the vertical cylindrical mill, and the pulverized coal is lifted to a powder separator byCoal Pulverization System: Explosion Prevention andCoal mill systems and their safety have taken a back seat for decades Of course, where there is not a focus on explosion protection, the supplier can create systems that are really dangerous There are numerous suppliers all over the world, butCoal Mill Safety
