Boiler efficiency is based mainly on the quantity of loss suffered by the system. In case of pulverized, high-capacity coal fired boiler, loss amounts to approximately 12-14 percent. 50 percent of losses are governed by different fuel properties such as moisture present in fuel, hydrogen in fuel including ambient air conditions. The remaining 50 percent losses are attributed to dry gas loss and carbon loss.
