Flue Gas Waste Heat Boiler Thermal Efficiency Calculation

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.
