Ceramic ferrules for boilers.

Both in the inlet and outlet ends. Ceramic ferrules are used at the inlet of the shell tube type heat exchanger to protect the tube inlets from hot gas corrosion and abrasive particle erosion. Ceramic ferrules for boilers. Engineered with thin walls tapered inlets and precise tolerances they serve to protect the weld integrity and first several inches while absorbing the brunt of the heat produced from the process.

This is accomplished through the separation of the structural and insulating functions of the ferrules. With the sulphur content of crude oil and natural gas on the increase and with the ever tightening sulphur content in fuels the refiners and gas processors will require additional sulphur recovery capacity. 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. Techno cera ferrules are manufactured using 98 high alumina.

Reliable oxytron oxide bonded silicon carbide wear resistant and high temperature ferrules are designed to be inserted in heat exchangers. Boiler tube inserts are also used in methane reformers and waste heat boilers whb. Ferrules for waste heat boiler incoloy 800ht cfbc. 2017 11 30 of package boilers and several hundred waste heat boilers that are in operation in in fire tube boilers ferrules and the refractory lining on the tube sheet.

4 7 entec fired heater and waste heat boiler in such cases ferrules or sleeves are usually placed in the tube inlet incoloy 825 and essentially none with types 310. Ceramic ferrules for boilers alumina ferrules techno cera ferrules ceramic ferrules are used at the inlet of the shell tube type heat exchanger to protect the tube inlets from hot gas corrosion and abrasive particle erosion. Refractory ferrules are designed to protect boiler tube inlet areas and metal tube sheets in sulfur recovery units srus used in oil refinery operations. Blasch ceramic ferrules provide more effective waste heat boiler tube protection and allow for much greater design flexibility than traditional refractory systems.

Refractory ferrules are made of materials called. A ceramic ferrule an array of ceramic ferrules and a ceramic ferrule refractory wall all for shielding a tube sheet boiler tube assembly of a heat exchanger connected to an industrial heat source. 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. Ceramic ferrules for waste heat boilers and claus furnaces.

The head portion of each ferrule replaces conventional cast refractory walls and has an outer peripheral shape that allows the ferrules to mate at the operating temperature of the industrial heat. Ceramic ferrules for boilers alumina ferrules ceramic. Techno cera ferrules are manufactured using 98 high alumina.
