Title: Design, operation, and testing of the fly ash Carbon Burn-Out pilot plant. Final report

Technical Report ·
OSTI ID:369708

The Carbon Burn-Out process beneficiates fly ash by reducing its carbon content, thus producing a byproduct with commercial potential as a concrete admixture while recovering heat liberated from the carbon in the fly ash. A one ton per hour Fly Ash Carbon Burn-Out pilot plant was designed and constructed in Tampa, Florida to demonstrate the process. Processing occurs in a unique fluidized bed containing only the fly ash particles. To date over 700 tons of fly ash from 11 different power plants have been processed at the plant. Feedstock fly ash carbon content varied from approximately 5 to 18%. The processed fly ash has carbon content in the 1 to 3% range. Test show that the low carbon fly ash product performs well in concrete as a cement extender or admixture.
