    Heat transfer between flue gas and feed water?

    I need to determine the temperature of flue gas in a fire tube boiler. Tube inlet gas temperature, T1 = 1045 deg.C Saturation water temperature, tsat = 186 deg.C Flue gas temperature, t2 = ? 2 equations to be used here: Q = U.A.LMTD -------------(1) Qg = Mg.Cg.(T1 - T2) ------(2)...
