Multiple-injection dry low-NOx combustor for hydrogen-rich syngas fuel: testing and evaluation of performance in an IGCC pilot plant

The successful development of oxygen-blown integrated coal gasification combined cycle (IGCC) technology requires gas turbines capable of achieving the dry low nitrogen oxides (NOx) combustion of hydrogen-rich syngas for low emissions and high plant efficiency. The authors have been developing a “mu...

The authors have been developing a “multiple-injection burner” to achieve the dry low-NOx combustion of hydrogen-rich syngas. This burner consists of multiple fuel nozzles and a perforated plate with multiple air holes. At each injection point, one fuel nozzle and one air hole are installed coaxially, so that a fuel jet surrounded by a sheath air jet is injected.
