A systems design is described for a combined cycle based on a High Temperature Turbine Technology 2600/sup 0/F combustion turbine operating with a low Btu coal-derived gaseous fuel. The Overall Plant Design is based on Westinghouse combined cycle PACE experience and achieves a calculated heat rate of 8336 Btu/KwHr. at a power output of 925 megawatts. The plant incorporates four combustion gas turbines and a steam turbine at 2400 psig-1000/sup 0/F-1000/sup 0/F--2.5 In. HgAbs., in a combined cycle suitable for base load application. The plant employs reheat with a number of interfaces between the steam-related components and the gasifier and ''cold'' fuel gas cleanup apparatus. The major interfaces include feedwater to and superheated steam from the gasifier system, hot reheat steam to the gasifier, process steam from gas cleanup to cold reheat, hot water to and from the gas cleanup system and a fuel heater which utilizes economizer water. The combustion turbines provide compressed air to the gasification system and receive the clean low-Btu gaseous fuel. The information presented constitutes the Overall Plant Design Description, including material on cycle and plant configuration, site plan, and the control system. In addition, the design requirements of the power plant are defined to include an integrated program on maintenance and reliability. Techniques available to analyze power plant equipment and systems from a reliability and availability viewpoint are described. Finally, a dissertation on various plant operating modes is presented along with a segment on a cycle utilizing an alternate high temperature ''hot'' fuel gas cleanup system.
