Waste Heat Recovery System (WHRS) - MAN Energy Solutions

The heat in the steam produced is about 95% of that lost by the gases passing through the boiler. Heat lost by hot gases = V s ( t 1 − t 2) MJs − 1, where V = m 3 gas/sec, s = specific heat (volume basis). Heat absorbed by water = 0.95 Vs ( t1 − t2 )MJ s −1, t1 and t2 = temperature of hot gases …

Flue Gas Waste Heat Boiler Thermal Efficiency Calculation

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 …
