High temperature corrosion in Waste Heat boilers

With time the deposited potassium chloride may sulfate to form potassium sulfate due to thermodynamically driving forces, but potassium sulfate has only been detected in insignificant amounts in mature deposits in straw-fired boilers formed over months of operation.The corrosion of superheater tubes is closely connected to the material which are deposited on the surface and deposits containing potassium chloride can cause severe high-temperature corrosion at elevated metal temperatures.

May 04, 2016 · Sulfite Test. Sulfite is added to boilers to remove dissolved oxygen, which causes severe pitting corrosion. Theoretically, it takes about 8 ppm of sodium sulfite to react with 1 ppm of oxygen. To assure that this reaction goes to completion and that all oxygen is removed, an excess of 30 to 70 ppm of sulfite should be carried in the boiler water.
