Abstract

In June, 1976, the U.S. Department of Energy (DOE) awarded a contract to an industry team consisting of Burns and Roe Industrial Services Corporation (BRISC), United Technologies Corporation (UTC), and the Babcock and Wilcox Company (B and W) for an ''Evaluation of a Pressurized, Fluidized Bed Combustion (PFBC) Combined Cycle Power Plant Design.'' The results of this program indicate that pressurized fluidized bed combustion systems,operating in a combined cycle power plant, offer great potential for producing electrical energy from high sulfur coal within environmental constraints, at a cost less than conventional power plants utilizing low sulfur coal or flue gas desulfurization (FGD) equipment, and at higher efficiency than conventional power plants. As a result of various trade-off studies, a 600 MWe combined cycle arrangement incorporating a PFB combustor and supplementary firing of the gas turbine exhaust in an atmospheric fluidized bed (AFB) steam generator has been selected for detailed evaluation. This volume contains information on commercial plant criteria, design, and cost.
