SOx Removal in Fluidized Bed Boiler Plants
SOx Removal in Fluidized Bed Boiler Plants
(OP)
Is it common to have SOx removal (scrubber) for the flue gas of a coal fired fluidized bed boiler? How many plants have a FB boiler with scrubbers?

These inert media are used if you are burning garbage or other material that would form a eutectic slag if limetone were used. In those cases, a scrubber is used.

A downstream FGD system can operate with Ca/S ratio as low as 1.1. The furnace bed can operate with Ca/S ratio as high as 2.5 (for very high efficiencies and high S content).
This may be true for very high sulfur fuels as petcoke (up to 7% S)
I think Jacksonville CFB power plant was planned this way.
