High Temperature Corrosion Phenomena in Waste to

In general, high temperature corrosion in WTE facilities typically occurs in three areas: top of the refractory lining in the first pass (including the waterwall tube), transition of the first to the second pass (including the boiler roof), and tube bundles of the screen, evaporator and superheater [6].

Boiler technologies from B&W Vølund - Babcock & Wilcox

Our boilers are normally water tube boilers and most often have four passes: three vertical radiation passes and a convection pass. The first of the radiation passes is integrated into the furnace as a post-combustion chamber. The convection pass, in which the evaporators, superheaters, and economisers are located, may be vertical or horizontal.
