What is a Waste Heat Boiler? (with picture)

Oct 04, 2019· In a reversal of the system inside a fire-tube boiler, waste heat, in the form of hot gases or furnace flames, surrounds the water-filled tubes. Insulating materials are used to protect the boiler tubes against flame damage. As well as tolerating high pressures, a water-tube waste heat boiler can respond quickly to changes in heat input.
