    The water-from-fuel loss is also dependent on the flue-gas exit temperature. The unburned carbon in the residue is related to how complete combustion is. The three main factors in determining efficiency are therefore flue-gas exit temperature, excess air and burnout, all of which are dependent on the technology.

    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.
