COAL BASED THERMAL POWER PLANTS: COAL MILLS FOR
13-12-2011A higher Hardgrove index indicates the coal is easier to grind. 50 HGI normally is taken for calculating the base capacity of the mill. When coal with HGI higher than 50 is fed to the pulverizer, the output will be higher than base capacity, and below 50 HGI, the output will be lower. The total moisture in coal has a high effect on mill output.

Dynamic classifiers: a fine way to help
07-04-2004UK power plants have little experience with the latest generation of dynamic classifiers. Recognising this, the UK power plant operator Powergen PLC ordered a single latest generation dynamic classifier for retrofitting to a 10E10 coal pulveriser at its flagship coal generating plant at Ratcliffe-on-Soar.
Pulverizer
Types of coal pulverizers. Coal pulverizers may be classified by speed, as follows: Low Speed; Medium Speed; High Speed; Low speed Ball and tube mills. A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods.
Detection of Malfunctions and Abnormal Working Conditions
02-05-2018Coal mill malfunctions are some of the most common causes of failing to keep the power plant crucial operating parameters or even unplanned power plant shutdowns. Therefore, an algorithm has been developed that enable online detection of abnormal conditions and malfunctions of an operating mill. Based on calculated diagnostic signals and defined thresholds, this algorithm informs about

How to Calculate the Coal Quantity Used in a Power Plant
15-10-2009Coal trader's web sites give base prices in the international market. We take a coal price of around 65 $ / Ton. The cost of coal consumed by 100 MW power plant is (53.8 x 65) 3497 $ /hr. A 100 MW unit produces 100,000 units of electricity. So the cost of coal per unit of electricity is (3497/100,000) 3.5 cents per unit.
