What is a Waste Heat Boiler? (with pictur

4/10/2019· @anon113733- A waste heat boiler is not a generator. It usually does not have a generator attached to it, although it can in an IGCC coal plant. In this system, it acts as a heat recovery steam generator. The flue gas heads into the heat recovery steam generator to boil water that creates steam to turn a smaller turbine.
