OPEN LETTER: How to fix the boiler and mill problems at

May 12, 2019The source of the problem is the coal pulveriser mills not being able to produce the more stringent fineness required. This results in coal/char particles burning higher up in the furnace, causing excessive reheater temperatures, etc. One could attempt to increase the rotational speed of the vertical spindle mills by at least 15%.

Boiler Performance and Mill Outlet Temperature

Nov 11, 2009Pulverizing mills in boiler plants play a major role in preparing the coal for firing in a boiler. Coal, being a heterogeneous fuel, varies in its properties; the variation depends on many factors like type of origin of coal, formation, etc.Two major parameters which decide the mill capacity and performance are the hardness of the coal and the total moisture level in coal.
