The Consortium for Coal-Water Slurry Fuel Technology, established under the aegis of the Pennsylvania State University, is currently developing technologies that would allow the United States to decrease its dependence on foreign oil and increase its use of coal. This work is being performed under the auspices of the Department of Energy (DOE) for the Department of Defense (DOD). The existing program is aimed at the development and demonstration of integrated combustion systems that would include coal-fuel preparation, delivery, storage and transport to the burner, combustion, heat recovery, ash collection, flue gas treatment, and system control. The objective of Phase I is to develop and evaluate technologies for retrofitting an existing DOD oil-fired boiler to fire premium coal fuels such as micronized coal-water slurry fuels (MCWSFs) and dry, micronized coal (DMC). Basic economics are developed and comparisons are made between the MCWSF and DMC fuels. It is found that MCWSF has a cost advantage over DMC at the point of supply only when considering supply of multiple retrofitted boilers from a single slurry preparation plant. The addition of transportation charges results in DMC being delivered to the boiler at a lower cost than MCWSF. The implications of the fuel cost differential between MCWSF and DMC towards capital costs of retrofitting are also discussed.
