ABSTRACT
Synthetic gas (syngas) is primarily a mixture of hydrogen (H2) and carbon monoxide (CO). Varying proportions of carbon dioxide (CO2), steam (H2O), nitrogen (N2), and small quantities of hydrocarbons, mainly methane (CH4), may also be present (Shilling and Lee, 2003). In order to employ syngas as a practical fuel for power and propulsion applications, detailed understanding and characterization of the key syngas combustion properties, such as self-ignition delay, flame speed, extinction limit, and heat-release rate, over a wide range of permissible fuel compositions, equivalence ratios, and operating conditions, will be necessary.
