A series of successful demonstrations of the IGCC system on a pilot plant scale have been conducted. The following conclusions are made: the advanced fixed-bed reactor is an effective and highly efficient converter of enthalpy as indicated by the high steam utilization, good cold-gas efficiency, and high average-gas quality; sulfur removal by the Benfield system met design goals and is sufficient to meet existing solid-fuel plant emissions specifications; there was no evidence of any operational problems with the Benfield (sulfur removal) system components; the average particulate loadings and alkali metal (Na + K) concentrations of the clean fuel gas confirm that a fixed-bed gasifier operating with a state-of-the-art, low-temperature cleanup system can supply fuel gas that can meet proposed commercial gas turbine specifications; air-cooled combustor components made with standard commercial alloys can be designed to operate efficiently at combustor exit temperature of 2700/sup 0/F; combustor and fuel nozzle components can be designed to burn low-Btu fuel gas at fuel-to-air ratios of up to 0.5 with acceptable exit-gas temperature profiles, dynamic pressures, and operating stability; the water-cooled gas turbine composite nozzles can be operated successfully at nozzle inlet temperatures of 2670/sup 0/F and 12 atmospheres; the water-cooled composite nozzle design is a successful concept with stable water flow distribution and is durable under severe test conditions; the total particulate loadings of low-Btu gas fuel are low enough to preclude any fouling of gas turbine airfoils by ash deposition; and although no corrosive deposits were detected and no indication of any corrosion on the water-cooled surfaces was found, it is almost certain that deposits would accumulate after longer operation times.
