Efficiency of a Coal Fired Boiler in a Typical Therma

Thermal efficiency reflects on the boiler operation & maintenance. Reduction in the boiler efficiency and evaporation ratio with respect to time is reported due to heat transfer fouling, poor combustion, operation & maintenance [4, 5]. Deterioration in the quality of fuel and water may also lead to poor boiler efficiency.
