Erosion Protection for Dry Scrubber Turning Vanes using Thermal Spray Coating by NanoSteel Co.

The NanoSteel Company is an advanced materials company which has created a unique and proprietary portfolio of nanotechnology based and environmentally friendly steel alloys that greatly increase the value of steel in most of today’s industrial applications.

Product success has been through the development of Super Hard Steel® (SHS) alloys which feature nanoscale microstructures. SHS alloys are for use as metallic coatings within power generation, mining, cement, concrete and oil & gas industries.

Applied by thermal spray and weld overlay processes, NanoSteel SHS alloys dramatically increase the service life of industrial components subject to wear and corrosion environments, eliminating the need for costly alternatives and environmentally dangerous chrome plating.

Material Loss from Severe Erosion

Spray drying absorption (dry scrubber) systems remove sulphur dioxide from flue gas at fossil fuel power plants.

NanoSteel Thermal Spray Coating for Turning Vanes

To reduce material loss on turning vanes inside dry scrubber unit at a coal fired power plant in Arizona, a NanoSteel® thermal spray coating solution is applied for resisting severe erosion.

SDA chamber walls are exposed to high heat and moisture during service.

Example of corrosion and pitting damage on SDA chamber wall ID.

Nanosteel coating resists corrosion and pitting damage.

NanoSteel Thermal Spray Coating Extending Service Life of Dry Scrubber Turning Vanes

The NanoSteel thermal spray coating provides resistance to severe erosion for reducing material loss, improving performance and extending the service life of vanes on the fixed dispersion ring.
