The anti-balance test method is usually used to measure boiler thermal efficiency. The calculation formula for the thermal efficiency of the anti balance method: η= 100- (q2+q3+q4+q5+q6) 1. q2-flue gas heat loss The exhaust heat loss is the heat loss caused by a part of the heat that is taken away by the smoke of the boiler. Its size is related to the amount of smoke, the smoke exhaust and the reference …

• ### Boiler Efficiency Calculation by Indirect Method

Boiler efficiency can be defined as the ratio of the useful heat output to the total energy input. (3.1) η = Q abs Q in. where. η is boiler efficiency. Qabs is the useful heat absorbed (heat transferred to steam) Qin is the heat and energy input into the boiler.

Aug 21, 2017 · Boiler efficiency levels are measured in percentages — either percent thermal efficiency or percent combustion efficiency. The new standard requires that commercial boilers have an efficiency level of 81-88%. But many of the modern boilers offer 90% efficiency, or even higher. Contrast this with the 65% efficiency of the old style cast iron boilers of 20 years ago.
