The off-gas from the fluidized bed combustor drives the gas turbine. The steam turbine is driven by steam raised in tubes immersed in the fluidized bed. The condensate from the steam turbine is pre-heated using waste heat from gas turbine exhaust and is then taken as feed water for steam generation.

Stanislav S. Naboychenko, in Handbook of Non-Ferrous Metal Powders (Second Edition), 2019. Fluidized Bed Furnaces. The reduction process is accelerated 3–4 times when using fluidized bed furnaces due to increasing the contact area between the powder and the gas-reducer. However, the reduction operations are more difficult to control than reduction in a conveyor furnace.
