抄録

Chemically Recuperated Gas Turbine (CRGT) is an advanced GT cycle that can increase power generation efficiency by recovering the exhaust heat with endothermic reaction of steam reforming. The CRGT fueled by Dimethyl Ether (DME) was demonstrated using 30 kW Micro GT (MGT) and accomplished both 10% reduction of fuel consumption compared with steam injected GT cycle and NOx- emission level of less than 10 ppm. Alternative fuel nozzle had concentric double pipe, one of which was designed to burn DME directly with diffusive combustion, and the other was premixed combustion of low-BTU reformed gas. The reformer, which was designed to fit into the MGT consisted of 96 SS 316-tubes filled with Pt catalyst and alumina balls, top and bottom headers and rectangular duct, recovered 15.3 kW heat from exhaust gas and increase heating value by 7.9%.
