Design and construction of a circulating fluidized bed

The design and construction of a proof-of-concept coal-fired CFBC for destruction of general and infectious hospital waste will be described. The design steam generation rate is 20,000 pph. A 42% reduction in fuel and waste disposal operating costs is projected as a result of t conversion from gas-fueled boiler to the coal-fired CFBC.
