A non-premixed, reformate and methane flame was experimentally and numerically investigated to explore the effect of steam to carbon ratio and reformate gas content on the criteria emissions generated. In order to better isolate the effects, the experiments were run at fixed flow rates and inlet temperatures. The steam to carbon ratio was varied from 2 to 3 while the reformate gas content was varied from 12.5% to 75% on a molar basis. Nitrogen oxide measurements were collected and analyzed to determine trends throughout the design space. Additionally, an OpenFOAM 2D model of the system was created, validated, and used to further investigate the system.
