Modelling and control of pulverised fuel coal mills

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). The reasons for this

Vertical Grinding Mill (Coal Pulverizer) Explained - saVRee

Coal pulverizers are used to dry, grind and classify. Drying is achieved as hot gas passes through the pulverizer and removes moisture from the pulverized coal. The hot gases used should have a low oxygen content, this reduces the likelihood of accidental combustion within the mill. It is possible for hot gases to be taken directly from the ...
