Preliminary design study for an integrated coal gasification combined cycle power plant. Final report

Abstract

This report presents the preliminary design, implementation schedules, and cost data for a fully integrated coal gasification/combined cycle power plant using the oxygen-blown Texaco Coal Gasification Process. The plant will have a net electrical output of 92 MW, and will be located at Southern California Edison Company's Coolwater Generating Station near Barstow, California. Three approaches for implementation of the plant were investigated: (1) Proceed initially with construction of the fully integrated plant; (2) proceed initially with construction of the coal gasification facility coupled to a new combustion turbine-generator only; and (3) proceed initially with construction of the coal gasification facility only, with the product gas fired in an existing boiler. In the latter two cases, the additional power-generation equipment required to complete the combined cycle would be added after a one-year testing program in the initial configuration. Cost estimates and schedules are presented for each of these three approaches to implementation. The report includes general arrangement drawings and complete performance and emissions data for the plant. Process flow diagrams, equipment lists, and system descriptions are presented for major systems in the plant.
