| Summary: | Recent concerns over declining landfill space and a renewed interest in waste-to-energy technologies have increased the possibilities of co-firing different types of fuels in fluidized bed combustion systems. Fluidized bed combustion systems are idea for co-firing because of their ease in heat conversion and ability to burn a wide range of fuels. Additionally, thermal analytical techniques can be used to screen fuel blends for the fluidized bed combustion systems at a lower cost than directly firing the fuel blends in pilot systems. Three coals, three different municipal solid wastes (MSW), one limestone were combined into nine series of binary fuel mixtures to determine the possible Observed/Theoretical ratios caused by the MSW and /or the limestone to the coal’s combustion profile. After doing so, optimum percentage combinations were determined that should combust efficiently in fluidized bed systems. Consequently, after the combinations were optimized, evolved gas analysis showed a possible 50% reduction in SO2 emission through absorption by limestone. |
