(i) For a given sample, ADB method gives the highest GCV value followed by EB method. The TMB method gives the lowest GCV value among the three methods. (ii) GCV on ADB basis gave undue advantage to the supplier since moisture present in coal, i.e., the sample, gets dried in the process for determination of GCV for payment to the

What is the difference between ARB and ADB? ARB puts all variables into consideration and uses the total weight as the basis of measurement. ADB (air-dried) basis neglect the presence of moistures other than inherent moisture unlike ARB which uses total moisture. This results in different measured GCV on different Basis.
