Development of a combustion system for the AGT 100 automotive gas turbine engine. The AGT 100 is a 100-hp engine being developed by Detroit Diesel Allison Division of General Motors Corporation. The work presented in this paper was conducted under contract with the NASA Lewis Research Center, with funding provided from the Department of Energy. To achieve optimum fuel economy, the AGT 100 engine operates on a regenerative cycle. A maximum turbine inlet temperature of 12800 Cel (2350 F) is reached, and air is supplied to the inlet of the combustor at temperatures as high as 1024 Cel (1875 F). To meet low-emission and high-durability requirements at these conditions, a premix/prevaporization ceramic combustor employing variable geometry to control the temperature in the burning zone has been developed. A test section capable of handling 1024 Cel (1875 F) inlet air was designed and fabricated to evaluate this combustor. Testing of both metal (transpiration-cooled) and ceramic combustors was conducted. Emissions were measued and found to be a function of burner inlet temperature. At 999 Cel (1830 F) burner inlet temperature (BIT), NOx emissions were two orders of magnitude below the program goals. At the same temperature but at a different variable geometry position, the CO was 30 times below the program goal. Considerable testing was conducted to evaluate the durability of the ceramic materials used in the combustor. (Wassmann)
