and the system brought off the line safely. Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will be ground to a more uniformly fine size

Explosion Protection for Coal Mills in Power Plants

Explosion Protection for Coal Mills in Power Plants. In order to ensure the safety of a coal mill in a power plant, three parts of the process have to be protected by REMBE products. The process starts in the mill containing the coal. Due to the fact that the coal is combustible material and can be ignited easily, the mill has to be protected.

In discussion Vincent Grosskopf, Coal Mill Safety

01-02-2019· 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.
