Documented $200,000 savings to one customer over the period, and parts are still running, accumulating savings
ALBANY, NY (11/13/2008) - A new family of Silicon Carbide parts replacing Cast Iron and NiHard Multicyclones in critical service in Power Generation applications has extended service life by more than 10 times. Back in 2000, Blasch replaced a number of cast iron cones in a multicyclone dust collector with something new - a cast Silicon Carbide cone - that was designed to directly replace, with no equipment modification, the metallic components that were in service.
Cones in this service - waste coal - are subject to tremendous abrasive wear, and typically 1/3 of all the hundreds of cones would be replaced every year.
"This was a source of great cost and time spent on the part of our customer, and we were able to eliminate it completely for nearly a decade", according to Tim Connors, Power Generation Market Manager at Blasch.
This original customer was pleased enough with the performance to report on it at the 18th International Conference on Fluidized Bed Combustion, in Toronto, Ontario.
How is this possible? Simple. Ceramic and metals wear in very different ways. Metals wear as abrasive particles are dragged across their relatively "soft" surfaces, and ceramics work best in that type of situation due to their much harder properties.
Blasch has done many such installations since that time.
How can other operating plants take advantage of this?
Find applications where there is abrasive wear from streams that strike surfaces at acute angles, not head on. Things like cyclones, elbows, and transition areas should be made from cast ceramic shapes, and not cast iron or NiHard.
Founded in 1979, Blasch Precision Ceramics serves a variety of manufacturing and processing industries throughout the world, providing innovative, customized solutions for chemically difficult or high temperature applications.
