*(1183) REDUCING THE PROBLEM OF WET COAL:CASE STUDIES IN THERMAL POWER PLANT
Abstract
The coal is used as a fuel in thermal power plants on a very large scale. Different grades of coal are used in power plants. The moisture content, volatile nature & ash content determines the grade of the coal. Out of these Moisture plays a very important part as it is present naturally within the coal & is added while handling the coal. So handling of coal becomes the section of prime importance for any power plant. As a result, coal handling units are installed by power plants for careful handling of the coal. This includes unloading, transporting, crushing, blending & conveying. These operations play an important role as the moisture from atmosphere gets added during the run. This paper thus attempts to highlight the issue wet coal with the help of three case studies. The case studies was successfully conducted, the details of which are discussed in this paper.References
