Unreliable ignition in a small volume combustor for a gas turbine may be avoided in a combustor construction including a generally spherical combustion chamber (10). The chamber (10) includes an outlet 14 diametrically opposite from an inlet (12) and a first injector (24) is disposed in the inlet (12) and includes an annular oxidant port provided with swirler vanes (36) and a fuel injecting head (46) provided with a ring-like series of fuel injection orifices (54) directed to inject fuel in a path (30) that is cone-like. A second injector (26) is included for injecting fuel into the chamber at or near the outlet (14) and an igniter (32) is disposed in the chamber (10) at the inlet (12). A small tube (38) is utilized to direct a small quantity of fuel at the igniter (32).
