Ash is one of the significant parameter in coal that greatly affects its calorific value, transportation cost, beneficiation and final thermal efficiency in power plants. Measurement of ash percentage (%) in coal is a time taking process in the laboratory and proves to be of little value in real time industrial conditions.
The instantaneous measurement of ash is now made possible by the non contact, nucleonic technology. The on-line coal ash monitor is designed for mounting the front end measuring c-frame across the conveyor carrying coal. The pc based electronics system is placed in a control room .the user friendly software displays ash percentage (%) and other relevant parameters and desired report printout can be obtained.
