✦ Synopsis

now Sithe Energies). More recent programs at GPU Genco, NIPSCO, Southern Company, Alliant Energy, and Allegheny Power Company have investigated and/or tested cofiring with more advanced concepts including blending biofuels with other opportunity fuels to design alternative energy sources for cyclone boilers, firing switchgrass and other agricultural products in PC boilers using separate injection, designing burners explicitly to optimize cofiring, and gasifying biomass in order to integrate biofuel cofiring into natural gas-fired electricity generating settings. This paper focuses upon some fundamental fuel consumption and associated combustion chemical considerations to consider recent results from cofiring programs, and to examine some of the opportunities and technical issues associated with eofiring. Williams, A. et al. Progress in Energy and Combustion Science, 2001, 27, (6), 587-610. This paper addresses the current status of the understanding of the combustion of pulverized coal and pulverized biomass from the viewpoint of computer modelling. While a knowledge of the underpinning science is of vital importance it's translation into applicable computer usable equations or computer data base libraries is of vital importance. A review is given of the current status of sub-models for the combustion of pulverized coal. Much of the information available for coal is transferable to biomass combustion although there are still areas where there is lack of information.
