      What is a Waste Heat Boiler? (with picture)

      May 27, 2020 · A waste heat boiler uses the heat formed as a byproduct of another process. Waste heat boiler design comprises two main types: fire-tube boilers, or shell boilers, and water-tube boilers. In fire-tube boilers, a steel shell encloses a water-filled space with metal tubes inside.
