Molten carbonate fuel cell power plants are candidates for two future utility applications. One application would be as small dispersed generators using liquid or gaseous fuels. The other would be as central station power plants fueled by coal. The activities conducted to develop and analyze molten carbonate fuel cell power plant design configurations for these two applications are described. Both small (5 MW) dispersed, oil-fueled and large (675 MW) coal-fueled power plants are considered. Plant requirements have been established and they include a heat rate of 7500 Btu/kWh for the oil-fueled plant and 6800 Btu/kWh for the coal-fueled plant. Described are the activities that will lead to the selection of a reference power plant design for each of the power plant types. These reference cycles will form the basis for assessments directed at economic evaluations and trade-offs designed to further improve and detail the plants. Plant design guidelines and the analytical methodologies developed in the course of this program are presented. Seven coal-fired and one oil-fueled plant configurations are identified and discussed. Three of the coal-fueled cases meet the heat rate goal. The oil-fueled case calculates to a 7882 Btu/kWh heat rate - the report discusses a means of more closely approaching the goal in this case.
