US5647432A - Ceramic ferrule and ceramic ferrule

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.

A Robust SRU Waste Heat Boiler Design

Mar 11, 2007 · Waste heat boilers (WHB) or heat recovery steam generators are widely used in the processing industry to improve energy efficiency1. In the petroleum refining and petrochemical industry, these WHBs are often an integral part of processing units such as Hydrogen Plants (HP), Sulfur Recovery Units (SRU), Fluid Catalytic Cracking Units (FCCU), and Olefin Plants, etc. Failures of these boilers

MECS® HexProTM Ferrules - Clean Technologies

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.

FAILURE ANALYSIS OF WASTE HEAT BOILER TUBES

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
