Find the (a) Specific Thrust Developed (b) Specific Fuel Consumption … WebFlue temperature is not just representative of heat transfer!! It also represents the firing rate and how much time the heat spends in the heat exchanger. A gas burner has a flame that reaches say 2800 degrees @ 6% O2. An Oil flame has a flame of about 3800 degrees @ 6% O2. A good flue temperature on gas would be 330 to 430. On oil 430 to 530.
