TL;DR: In this article, the NH 3 -air combustion power generation has been successfully realized using a 50kW class micro gas turbine system at the National Institute of Advanced Industrial Science and Technology (AIST), Japan.

TL;DR: In this paper, the effects of fuel injection angle, combustor inlet temperature, equivalence ratio, and ambient pressure on flame stabilization and emissions were investigated in a laboratory high pressure combustion chamber.

TL;DR: In this paper, the authors used Particle Image Velocimetry (PIV) and Planar Laser Induced Fluorescence (PLIF) imaging, in addition to Fourier Transform Infrared (FTIR) gas analysis to study the flow field, flame structure and emissions characteristics of a micro gas turbine swirl combustor fuelled with CH4 NH3-air mixtures.

TL;DR: Based on the global demand for carbon-free power generation as well as recent advances involving gas-turbine technologies, such as heat-regenerative cycles, rapid fuel mixing using strong swirling flows, and two-stage combustion with equivalence ratio control, a low-NOx NH3-air non-premixed combustor was developed by using a 50kWe class micro gas-to-power system at the National Institute of Advanced Industrial Science and Technology (AIST), Japan, for the first time.

TL;DR: In this paper, the authors investigated the combustion and emission characteristics of turbulent non-premixed ammonia (NH3)/air and methane (CH4)/air swirl flames in a rich-lean gas turbine − like combustor at high pressure under various wall thermal boundary conditions.
