Dependence of unburnt ammonia on combustor inlet temperature of ammonia combustor of micro gas turbine
The Proceedings of the National Symposium on Power and Energy Systems(2019)
摘要
It is important to increase combustion efficiency of ammonia gas-turbine combustor. Concentration of unburnt ammonia depends strongly on combustor inlet temperature in the case of the previous combustor. Emissions of unburnt ammonia is high under 500℃ of combustor inlet temperature. In the case of rich-lean low-NOx combustor, concentration of unburnt ammonia does not depend on combustor inlet temperature. Low emission of unburnt ammonia of 15ppm (16%O2) is recorded at 313℃ of combustor inlet temperature. In the case of rich-lean low-NOx combustor, it is thought that the gas-turbine without regenerative heat exchanger can apply high combustion efficiency to ammonia combustor. It means that it can be used for the larger gas-turbine systems.
