In some circumstances, steam demand increases are so disruptive to boiler operation that boiler life as well as steam quality suffers. In some cases, the external water level indicator shows the water level as satisfactory, yet the actual level of the water/steam mixture in the boiler may be filling the steam space and water may be literally pouring into the steam lines by steam demand syphoning.

This efficiency can be calculated using the formula: η= (Energy output)/ (Energy input) X 100. To measure boiler efficiency in this way, we divide the total energy production of a boiler by total energy input provided to the boiler, multiplied by a hundred. Calculation Formula of direct efficiency of boiler-.

Assuming the boiler has 75 t/h capacity, high pressure steam is produced at 38 bar and 440°C which represents 59 Gcal/h of thermal power. When this boiler works at 90% efficiency, thermal power becomes 53 Gcal/h. Due to a high oxygen level in the boiler, a 1.4% loss in efficiency occurs and thermal power reduces by 0.74 Gcal/h to 52.3 Gcal/h.
