Combating hot corrosion of boiler tubes – A study

Feb 01, 2013 · Essentially two systems have evolved one against erosion wear in coal fired boilers and one for corrosion resistance in waste incineration boilers. In coal fired boilers, boiler tube wear occurs from erosion by hard particles (quartz) in the gas stream. The solution is to coat the tubes with a thin (0.7mm) but very hard (750-1000 HV) metal coating.
