Energy Tips Steam

A conventional feedwater economizer reduces steam boiler fuel requirements by transferring heat from the flue gas to the boiler feedwater. For natural gas-fired boilers, the lowest temperature to which flue gas can be cooled is about 250°F to prevent condensation and possible stack or stack liner corrosion.

Firing rate versus flue temperature Heating Help: The Wall

Flue 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.
