... (NO x ) emissions. Indeed, several studies in the combustion literature have reported elevated NO x concentrations in terms of dry ppmv NO x at 15% oxygen (O 2 ) as a fuel’s H 2 fraction is increased. Yet, as emphasized in this work, this practice of directly comparing emissions on the basis of dry...
