IET Digital Library: Modelling and control of pulverised

An area of power plant control that has received much less attention from mod elling and control specialists is the coal mills This is in spite of the fact that it is now accepted that coal mills and their poor dynamic response are major factors in the slow load take-up rate and they are also a regular cause of plant shut-down (Maffezzoni 1986) Get price
