Coal fired boiler: How to derive optimum efficiency

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

Pulverized Coal Fired Steam Boilers | Coal Fired Boilers

Crushed coal from the raw coal bunker is fed by gravity to a dryer where hot air is passed through the coal to dry it. The dryer may use waste flue gasses, preheated air or bleeder steam as drying agent. The dry coal is then transferred to the pulverising mill. The pulverised coal obtained is transferred to the pulverised coal bunker (bin).
