If the boiler fuel contains Sulphur (and most do) combustion products in the flue gas will include Oxides of Sulphur (SO2 and SO3). SO3 combines with water (H2O) to make Sulphuric Acid (H2SO4). If the temperature of the flue gas falls below the dew point, the combination of the acid with the moisture in the flue gas causes corrosion of the flue gas duct work. Bypassing the economiser in the early stages of a boiler start keeps the flue gas temperature above the dew point.
