Ceramic Ferrules For Waste Heat Boilers | Tech Ceramic

Ceramic Ferrule For Waste Heat Boilers. The waste heat boiler (WHB) is arguably the most fragile part of an sulfur recovery unit (SRU) and is subject to sudden and very costly failure. The most common failure is the tube to tubesheet joint where temperature can become unacceptably high, causing the welds to fracture and the joints to fail.
