Industrial Boiler Efficiency Calculation & Factors

Thermal efficiency assesses the effectiveness of the heat exchanger by analyzing its ability to transfer heat energy to the water or steam within the boiler. However, this calculation does not account for external factors such as ON-OFF losses, radiation losses, convection losses and more, so it is not the best indication of the boilers' fuel
