2018-9-19 · Fuel to Process Heat to Electricity. The waste heat left over from an industrial Heat process (e.g. furnace, dryers, thermal oxidiser, etc.) is directed to an HRSG, which uses the waste heat energy to generate steam. The steam is generally expanded through a steam turbine generator, to produce electricity. In this Bottoming Cycle process, of
