A Sustainable Innovation for Protection of Coal Burner Tip

May 01, 2000 · Abstract. The erosion durability of three tube materials that are generally used in the heat exchangers of steam boilers was tested by having an air flow containing particles flowing through tube banks. The materials tested were St35.8, 15Mo3 and 10CrMo910. The last one was most resistive …

Erosion resistant coatings for steam turbines: Final

The tubes damage rate depends on the boiler design bed constituents and combustion parameters, however an accelerated metal wastage is usually found in the same specific areas of different boilers. New HVOF sprayed coatings are developed for the tube erosion-corrosion protection, based on Cr{sub 2}C{sub 2}/Ni-Cr, Cr-Ti-C/Ni-Cr-Mo, and Al{sub 2

Wear Protection: New wear and corrosion preventative

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.
