Summary: The below biomass fuel analysis (Laboratory ID Number
AC24135) was performed by the Southern Research Institute (the
engineering research arm of The Southern Company) for energy
crop
(closed loop biomass) eucalyptus fuel used at our co-firing test
burn at Lakeland Electric's McIntosh 3 Unit (a 365 MW pulverized
coal boiler).
An additional source for both fuel and air emission data can be found in the Tampa Electric Energy Crop Co-firing Report on their Polk Power IGCC Unit.
