Ferrules For The Waste Heat Boiler

Factors Affecting Claus Waste Heat Boiler Design and Operation

Avoiding conditions of steam blanketing on the boiler tubes is important. The heat flux rates over the entire tube length of the WHB should be evaluated, especially the turbulent entrance area near the end of the ferrule. The heat flux should not exceed 50% of maximum nucleate flux at design, and 65% for maximum service conditions.

Waste Heat Boilers - Sulphuric Acid

Boilers in acid plants are waste heat boilers cooling gases from sulphur furnaces, regeneration furnaces and between catalyst beds. Types of Boilers. There are basically two types of boilers in common use: 1) Firetube 2) Watertube. Firetube Boilers. In firetube boilers the hot gases are confined within tuibes arranged in a bundle within a shell.

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.

Refractory Ferrules Selection Guide | Engineering360

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. Refractories are suitable for applications requiring wear resistance, high temperature strength, electrical or thermal insulation, and other specialized characteristics.
