Fireside corrosion will occur when the flue gases are cooled below the dew point and come in contact with carbon steel pressure vessel. To avoid corrosion, the heating systems should be designed to operate in a way that ensures a minimum return water temperature of 150 F to the boiler. (Note: It is important to verify the return water temperature with the manufacturer's literature to avoid corrosion.) All heating components should be selected to operate with a minimum supply water temperature of 170 F, assuming 20 F differential temperature across supply and return water lines.
