Sep 23, 2020 · The thermal efficiency of a boiler is the percentage of the heat available from the fuel. The heat of gas boilers to produce hot water or steam mainly comes from the heat generated by fuel combustion. However, the fuel entering the boiler cannot be completely burned and released for various reasons, and the heat released by combustion will not be effectively used for the production of steam …

Read MoreWhen this boiler works at 90% efficiency, the thermal power is 71 Gcal/h. Due to the high stack gas temperature of the boiler, a 3.5% efficiency loss occurs and the thermal power reduces by 2.4 Gcal/h to 68.6 Gcal/h. The economic loss is calculated as $79.2/h. Effect of excess air on boiler efficiency

Read MoreEfficiency of steam boilers plays an important role in profitability of the whole project. As fuel costs are huge, and are considered as one of the biggest production costs, even slight variations in efficiency of a steam boiler can singlehandedly make the operations inviable.
