Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.

The Court allowed a taxpayer to reduce its black lung excise tax by the additional weight of coal sold which resulted from weight of the excess moisture of the coal.
