The primary Pressurized Fluidized Bed Combustion (PFBC) concepts being developed within the DOE PFBC program with conventional coal-fired technology are compared. A more conservative PFBC cycle is also evaluated. A normalized performance analysis showed that both PFBC cycles are significantly more efficient than conventional power plants; the steam cooled PFBC has a greater performance advantage than the air cooled PFBC cycle; and a more conservative PFBC cycle employing turboexpanders was an attractive option that could serve as a first generation PFBC power plant. The air and steam cooled PFBC costs and the conventional coal fired plant costs were compared. It was concluded that the steam cooled PFBC appears most attractive on the basis of capital cost. A subsequent COE analysis demonstrated that the performance and capital cost benefits of the steam cooled PFBC result in a significant economic benefit when compared to conventional technology, and certainly demonstrates that PFBC is a promising new technology. The turboexpander PFBC power plant is competitive on a cost of electricity basis with conventional coal fired power plants. It was also concluded that the air cooled PFBC will only see commercial application if breakthroughs in materials technology occur or a hybrid air/steam cycle is developed, but it is recommended to continue with the air cooled PFBC pilot plant as an excellent turbine test facility. This volume contains information on PFBC concepts and designs; PFBC test data; normalization of plant configurations; conservative PFBC plant design; and performance assessment. (LCL)
