Heat salvage - ScienceDire

Economizers are regarded as an integral part of a boiler plant. The chapter describes heat salvage from flue gases at atmospheric pressure in water-tube boilers. However, most of the principles discussed in the chapter apply equally to heat salvage in fire tube boilers and from other fluids.

Superheater - an overview | ScienceDirect Topi

An in-line tube arrangement, Fig. 5.5 is preferred for boilers where fouling resistance is important (Teir, 2004). Such boilers are grate-fired boilers, solid fuel BFB and CFB boilers like bark boiler and kraft recovery boilers. The staggered arrangement is often only used in oil, gas, and heat recovery boilers.

US8518496B2 - Preventing tube failure in boilers

The erosion-prone sections of the tubes in a circulating fluidized bed boiler are provided with a locally thickened sidewall without forming discontinuities on the outer surface of the tubes. This can be accomplished, for example, by replacing the erosion prone portion of the tube with a section having a smaller inside diameter, but the same outside diameter, or by replacing the erosion prone
