High-temperature-turbine technology program: overall plant design description (OPDD), low-Btu coal-gas electric power plant

This report describes the Low-Btu Coal Gas Combined Cycle Electric Power Plant concept developed during Phase II of the US Department of Energy High Temperature Turbine Technology (DOE-HTTT) Program. The report defines a highly reliable, commercially viable system based on coal-derived fuel. This definition builds on and updates the Phase I study of the Low-Btu Coal Gasification Combined Cycle System. The system consists mainly of high-temperature, water-cooled gas turbines that burn coal-derived gas fuel, and a steam bottoming cycle with one reheat steam turbine. The coal gasifiers, low-Btu gas cleanup, and plant support equipment definitions are also based on approaches initially described in DOE-HTTT report FE-1806-23, High-Temperature Turbine Technology Program, Overall Plant Design Description, Low-Btu Coal Gas Electric Power Plant. Significant changes (from Phase I) in the hardware and its functional sequencing are included and a more detailed description of the organization, operation, and control of the integrated system is presented. The main changes are the addition of a Raw Gas Steam Generator (RGSG) at the gasifier exit and the use of the smaller PRD-6 gas turbines in lieu of the PRD-7 gas turbines.
