Derivation and validation of a coal mill model for control

May 01, 2012Coal 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, there are 4–8 coal mills
