ABSTRACT
Lean premixed combustion is the technological foundation for the ultralow NOX industrial burners and for the dry-low-NOX (DLN) method employed in state-ofthe-art low-emissions gas turbines. Though effective, the lean premixed combustion method is hampered by undesirable side effects, such as flame instability and combustion oscillations. These problems can be exacerbated by the variations in the combustion properties of syngases. Therefore, understanding how the basic properties of premixed turbulent flames change with fuel compositions is essential to the development of fuel-flexible combustors that can burn a variety of syngases derived from coal gasification.
