The heat efficiency of a flue gas waste heat boiler is the percentage of the effective heat in the heat injected into the fuel. 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 …
