Coal liquid combined cycle reference design

Abstract

The objective of the Energy Research and Development Administration - High Temperature Turbine Technology (ERDA-HTTT) Program is to bring to technological readiness within six years a high-temperature turbine for use in a combined cycle using coal-derived fuel at a firing temperature of 2600/sup 0/F with growth capability to 3000/sup 0/F. The program is to be conducted in three phases: Program and System Definition, Technology Testing and Test Support Studies, and Technology Readiness Verification Test Program. The objective of Task 2 is: Establish Baseline Combined Cycle System(s) for Gas and Liquid Fuels. This topical report on the baseline design presents information for Case C, the coal-derived liquid (CDL) combined cycle plant. The report is organized to present initially an overall picture of the plant arrangement. It then describes separate parts of the plant, including the CDL storage and forwarding system, the combined cycle power island arrangement, design of the high-temperature gas turbine and control system, plant control, failure mode analysis, plant costs, and power generation costs. The CDL plant is quite similar to a distillate-fired combined cycle plant. Major plant parts where system design descriptions (SDD's) are presented include CDL fuel forwarding and cleaning, the gas turbine system, and the integrated plant control.
