New Large Particle Ash Screens Feature NanoSteel’s Thermal Spray Coating Alloy

The NanoSteel® Company, a leader in surface coating technologies, announces the launch of the company's LPA Screen product line which extends SCR catalyst service life through enhanced protection from bed plugging by reliable screening of Large Particle Ash (LPA).

NanoSteel LPA Screens feature the company's patented Super Hard Steel® (SHS) 8000 ultra low wear thermal spray coating alloy which can more than double screen life. SHS 8000 features a nanoscale microstructure which provides a unique combination of high hardness and toughness properties resulting in superior erosion resistance, high coating bond strength and the ability to deform with the screen substrate material upon impact without chipping, cracking or delaminating.

"NanoSteel SHS 8000 is a proven thermal spray coating material in power generation for protecting boiler tubes and components in dry scrubber units," says Dave Paratore, president and CEO. "We are expanding this material's use for operators/owners of coal plants with SCR systems to increase the life of the SCR catalyst. Our new LPA screens maintain their geometry longer than other screen products which prevents ash build up from causing expensive damage to the SCR reactor and catalyst layers. In addition, by protecting the catalyst bed from LPA contamination, ammonia slippage will be minimized, resulting in lower operating costs and overall lower NOx emissions."

NanoSteel LPA Screens are engineered to fit existing or new screen systems. NanoSteel can deliver ready-to-install LPA screens built to print or dimensions, in various design patterns and in any size.
