One of the overall goals of the U.S. Department of Energy (DOE) is the development of the technology necessary to provide for a secure, reliable, affordable, and environmentally sound source of energy. This is important in order to ensure economic stability and growth in the next century as well as to reduce current and minimize future environmental impacts associated with power generation in the United States and the world as a whole. In order for coal to play a key role in the U.S. energy mix, technologies must be developed and commercialized that are capable of producing electricity at significantly higher overall system efficiencies than the 30%-35% levels currently observed in conventional coal-fired systems. Also, the production of liquid and gases us fuels from coal will be necessary in order to effectively meet the broad spectrum of future energy needs. In order to achieve overall system efficiencies of 40% to 60% in an environmentally acceptable manner, development and demonstration of advanced second-generation utilization and conversion technology will be necessary. Examples include (1) advanced pulverized coal- fired combustion systems; (2) high-temperature heat exchangers for indirect Bring of gas turbines; (3) pressurized combustion in staged, entrained, slagging, and fluidized-bed modes; and (4) integrated gasification and direct gas-fired turbines. A number of barrier issues exist that are not unique to individual technologies but are in some manner common to all advanced power system processes for both oxidizing and reducing environments. Examples include materials issues, specifically ceramic and refractory components, and operational issues unique to high-temperature pressurized systems. These operational issues include a comparison of pressurized fluidized-bed combustion (PFBC) performance utilizing dry (powdered) versus wet (slurry) coal feed systems.
