2019/9/23 · In a waste heat boiler, the heat from the gas is recovered as saturated or super-heated steam. The boiler must be designed to operate reliably with acidic gases, and often sticky dust as well. For some applications, the effort required for energy recovery does not justify the use of a boiler.
