How to convert coal from one moisture content to another also from one ash content to another. The intention is to understand the change in GCV with variation in moisture and ash content.
Thanks

What will be the fornula to calculate FC in to GCV if test/analysis conducted on AD basis.

For example : We are getting report on ADB and the FC is shown as 46.5 % ,what will be GCV ? Please guide us the conversion or formula.

hello

Thank you for this informative article. I have a question though, I want to know why it is necessary to do an ultimate and proximate analysis of coal when calculating the efficiency of a coal fired boiler?
