2012年5月1日  Coal fired power plants are heavily used due to large and long lasting coal resources compared with oil or natural gas. An important bottleneck in the operation of this particular kind of plants, however, is the coal pulverization process, which gives rise to slow take-up rates and frequent plant shut-downs (Rees Fan, 2003).In typical coal fired power plants,

In discussion: Coal Mill Safety. 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.
