This report evaluates the environmental characteristics of, and technical issues currently associated with, pressurized, fluidized-bed combustion (PFBC) systems fired with coal. The PFBC concept is being studied worldwide in pilot and bench-scale facilities. A PFBC system normally burns coal, along with alkaline sorbents, in a pressurized reactor; the energy generated is recovered in gas turbines and steam turbines. The PFBC combined-cycle system is expected to improve thermal efficiency and reduce SO/sub 2/ and NO/sub x/ emissions without the need for post-combustion scrubbing - and with the attendant potential, therefore, of producing electricity less expensively than can be done when scrubbing is required. 41 references, 12 figures, 8 tables.
