  • Two criteria for boiler tube bends are ovality and wall thickness. Using ASME Section II, SA 450 - "Specification for General Requirements for Carbon, Ferritic Alloy and Austenitic Alloy Steel Tubes", section 7 "Permissible Variations in Wall Thickness", and Section 8 "Permissible Variations in Outside Diameter" give the necessary guidance for acceptable tube tolerances.

  • Boiler Bank Tubes carry a mixture of water and steam. Fabricated from Tubes in various sizes and shapes, bending of these tubes is generally to larger Radius hence they need some Tube Bending Expertise to avoid wrinkles, surface cracking, irregularities, ensuring long life of tube resulting in smooth and efficient operation of the Boiler.

  • Superheaters are generally placed where the flue gases are hot. There is still a lot of molten ash and reactive gases. This places an extra burden on the mechanical construction of superheaters (Gaffert, 1981).Because superheaters have to be built for optimal behavior in an often hostile environment that differs from boiler to boiler, there are very many different types of superheater (Fig. 7.4).

  • A superheater where tubes are placed in an in-line configuration and close to each other in the flue gas flow direction is called a panel superheater, Fig. 5.6. In panel superheaters the tube longitudinal spacing is smaller than 1.25×Ø d. The panel superheater is more resistant to fouling and erosion and can withstand a high heat flux.
