plant, making co-fired power plants that can run on either feedstock (or both in parallel) financially appealing. Since coal is more energy dense and the resource is more geospatially concentrated relative to biomass, coal transport can be economical over greater distances. Thus, most coal power plants are at least an order of magnitude larger

The main function of the Primary air fan or PA fan is to carry the pulverized coal to the furnace as fuel for combustion. This process is used to create the steam that is the primary process in the thermal power plant. In power plants, the PA fans supply air for conveying of the pulverized coal from coal mills to the furnace area.

of power plant control that has received much less attention from modelling and control specialists is the coal mill. It is now accepted that the coal mills and their poor dynamic response are major factors in the slow load take-up rate and plant shut-down. A Coal mill model using Evolutionary computation technique reported in [1].

The operating costs of breaking coal particles into fine powder, to achieve optimum combustion for the boilers in a power plant, are made up of power input to carry on an energy intensive comminution mechanism and to overcome friction losses within pulverising machines. The operating costs also include the cost of the replacement of the processing system's components due to wear.
