Chloride level in Boiler feed water - Corrosion

Oct 13, 2015 · In high pressure boiler, by using the sodium sulphite, the sulphite can break down to give hydrogen sulphide which can attack steel brass and copper. If chloride is found too much in your boiler water what will you do ?

chlorine attack starts at 204oC while hydrogen chloride attack will occur until a temperature of about 426oC. A suitable material that is suggested to be used in power station boilers, that has a high resistance corrosion rate is Stainless steel (AISI 310); substantial research has shown that it can be utilized in super-heater tubes. Keywords: Chlorine, Sulphur, Stainless steel (AISI 310), High temperature …

Effect of Chlorine and Sulphur on Stainless Steel (AISI

Chlorine can contribute boiler tubes. The extent of corrosion to corrosion of depends on the Flue Gas Oxidation/Reduction Poten- tial. Boiler tube wastage has become a more noticeable problem for many coal-fired units sulfur and chlorine may increase greatly. The chemical species present in the coal ash are verv sensitive to the flue gas oxygen/
