Abstract
A demonstration test with the aim to show the potential of an ammonia-fired power plant using a micro gas turbine is planned. A 50 kW-class turbine system firing kerosene is selected as the base model. A standard combustor is replaced by a prototype combustor, which enables a bi-fuel supply of kerosene and ammonia gas. Diffusion combustion is employed in the prototype combustor to ensure flame stability. The demonstration test with kerosene and ammonia gas co-firing was conducted to verify the functionality of each micro gas turbine component. The gas turbine started firing kerosene and increasing its electric power output. After achieving a stable power output, ammonia gas was supplied with a gradually increasing flow rate. 17 kW of power generation was achieved with a 38% decrease of kerosene, replaced by ammonia gas, which increases NOx in the exhaust gas dramatically. However, a decrease of the NOx can very well be obtained by the supply of ammonia gas to the catalyst.
