Waste Heat Boiler Design Calculations


Waste Heat Boiler - an overview | ScienceDirect Topics

Heat absorbed by water = 0.95 Vs(t 1 t 2)MJ s 1. t 1 and t 2 = temperature of hot gases before and after the W.H. boiler °C.. Total heat as steam = sensible heat in feed water + heat absorbed by water in . In good practice t 2 the temperature at which the flue gases leave the may be reduced to ca.50 K above the temperature of the water in the .

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 formula for the thermal efficiency of the anti balance method: = 100- (q2+q3+q4+q5+q6) 1. q2-flue gas loss
