Ceramic Ferrules: One & Two Piece | Blasch Precision Ceramics

Ceramic Ferrules: One & Two Piece. Blasch ceramic ferrules provide more effective waste heat boiler tube protection and allow for much greater design flexibility than traditional refractory systems. This is accomplished through the separation of the structural and insulating functions of the ferrules. …

A Robust SRU Waste Heat Boiler Design

shell Waste Heat Boiler (WHB) design generating nominally 600 psig saturated steam. The WHB first pass used 400 2-1/4" OD SA 213-T11 tubes and the second pass used 400 2-1/4" OD SA 210-A-1 tubes and the inlet tubesheet was 2" thick SA 516-70N. The tubes were rolled, seal welded and re-rolled and a

The axial length Lh of head portion 2 is sufficient to shield the inlet tube sheet from the heat of the waste gas. Preferably, Lh is at least about 1/2 the overall axial length L of the ferrule. FIG. 4A is a plan view showing an array of ferrules 1 installed in boiler tubes of an inlet tube sheet.

Tube Inserts and Pipe Ferrule,Used in Heat Exchangers

Tube inserts and Tube ferrules are a metal inserted into the end of a heat exchanger tube to provide protection to the Tube mouth ends of a shell & tube type heat exchanger. The need for this Tube Ferrule arises as all tube failures occur within the first few inches of the heat exchanger tube inlet-end. The solution to this situation is the use

Waste heat - Wikipedia

Waste heat is heat that is produced by a machine, or other process that uses energy, as a byproduct of doing work.All such processes give off some waste heat as a fundamental result of the laws of thermodynamics.Waste heat has lower utility (or in thermodynamics lexicon a lower exergy or higher entropy) than the original energy source.Sources of waste heat include all manner of human

FAILURE ANALYSIS OF WASTE HEAT BOILER TUBES

A petrochemical plant was shut down due to tubes leaks in a waste heat boiler (WHB). The failed WHB has been in operation for about 20 years, without any previous failure. Following the incident, inspection activities revealed the following: • Leaks were observed at 7 tubes. • Localized damage was observed on 70% of the ferrules.

FOR WASTE HEAT BOILERS AND HEAT EXCHANGERS IN …

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.

Engineered Ferrules for High Temperature Waste Heat

Refractory ferrules are designed to protect boiler tube inlet areas and metal tube sheets in sulfur recovery units (SRUs) used in oil refinery operations. Boiler tube inserts are also used in methane reformers and waste heat boilers (WHB). Refractory ferrules are made of materials called refractories that have high melting points.
