Abstract

This paper presents an experimental and numerical study to elucidate the suppressing influence of H₂ content in syngas on OH formation in laminar syngas diffusion flames burning in coflow oxidizer of 25%O₂/75%H₂O. Such an influence was found different from the effect of H₂ content in syngas on OH formation when the oxidizer stream consists of O₂/N₂. OH^∗-chemiluminescence images were captured using an intensified CCD (ICCD) camera, the centerline temperatures were measured by a Pt-6%Rh/Pt-30%Rh thermocouple, while a two-dimensional flame code was adopted to simulate these laminar coflow diffusion flames using a detailed reaction mechanism. The different effects of H₂O including chemical, thermal, transport, and radiative were examined and detailed kinetics analyses were conducted to gain insights into how H₂O in the oxidizer stream alters the influence of H₂ content in syngas on OH formation.
