Jan 31, 2022 · A waste heat boiler of the water-tube design is able to cope with much higher pressures of steam than a fire-tube boiler, but it is more difficult to construct and install. Inside this type of boiler, there are narrower tubes than inside a fire-tube boiler, and the tubes contain water instead of hot gases.

As a word of caution, such waste heat boilers are sometimes designed and operated so that waterside circulation is inefficient, areas of unavoidable deposit accumulation are numerous, and
Read moreUsing a principle similar to economizers, waste heat boilers recover heat generated in furnaces or exothermic chemical reactions at industrial plants. These locations may contain significant energy that should not be wasted up a stack. Instead, this energy can be captured to generate low-to-medium pressure steam in a waste heat boiler (WHB).
