Abstract:
In an igniter for a combustor in a gas turbine engine, a fuel and air distribution means comprising a tubular member having an axial bore with a first end near the igniter such that the igniter tip is at the first end of the bore and the second end of the tubular member and bore communicates with the combustor, the tubular member is a porous material chosen from a material having a high thermal tolerance, a cavity defined behind the igniter tip relative to the axial bore and means are provided for supplying air to the cavity, a casing defining a plenum surrounding a portion of the tubular member and an air inlet for communicating high pressure air within the plenum, a fuel inlet to feed fuel to the tubular porous member such that the liquid fuel is retained and distributed by capillary action towards the axial bore of the tubular member where the liquid fuel will vaporize to form an atomized mixture and the high pressure air will serve to cool and dry the tubular porous member of fuel.
