any residual coal left within the mill will oxidise, which can explode as the mill is restarted. To prevent a coal fire, the mills can be inerted with a steam deluge when an unexpected shutdown occurs or when there is a high risk of a coal fire. Safety methods Several methods are available to detect the presence of oxidisation within the mill
Feb 01, 2019 VG At best, coal mill safety is not well understood and, at worst, it is ignored. When it comes to coal mill systems, most cement plant operators just presume that the supplier of the equipment knows all of the standards and rules and is 100 capable of making a system that conforms to these and is therefore safe. However, this is not the case.
