Boiler Cold End Corrosion - Mechanism an

Flue gas exhaust temperature. The usual method employed to minimize the cold end corrosion by maintaining the flue gas exhaust temperature above the dew point. The temperature difference shall be of 20 o C between the flue gas and dew point. The boiler efficiency will be reducing with the increasing of temperature difference. Removing the catalyst

ACIDDEWPOINT.C

Unlike traditional Acid Dew Point Meters, the AbSensor-ADM measures the dew point of combustion and process gases, independent of the condensable species (i.e. Dew Points of ammonium bi-sulfate, sodium bi-sulfate, sulfuric acid, water, etc.) and hence would be applicable for a wide variety of corrosion and fouling applications.

USING BOILER FLUE TEMPERATURE TO CALCULA

2011-4-7·heat radiated outwards, instead of into the boiler water, typically raises the temperature of the boiler room, thus pre-heating the combustion air. An Extreme Case UWT typically encounters boilers operating at significantly higher flue temperatures. A sample 400 horsepower boiler was found to have a flue gas temperature of 540 degrees F.

PROFILE IN LOW TEMPERATURE . Some of the sulfur in the fuel will be oxidized to SO3 which will react with water vapor to form sulfuric acid condensing on surfaces when temperatures are below its dew point. This can also occur when the temperature of the flue gas is above the dew point and the deposits insulate the heat-exchange surfaces.
