ABSTRACT:
A gas turbine combustor is ignited by a torch igniter. The ignition chamber of the torch igniter receives a swirled stream of air into which is injected atomized fuel. The mixture of fuel and air is ignited by a spark plug in the ignition chamber. The combustion products and igniter flame are exhausted from the ignition chamber through a gas passageway penetrating through the sidewall of the gas turbine combustor to ignite a flame in the combustor. The igniter flame and the combustion flame are detected by a U.V. detector looking through aligned igniter air inlet and igniter exhaust passageways into the combustor. A U.V. transmissive window is disposed in the air inlet passageway to isolate the detector from the pressure of the igniter and combustor. A swirler in the air inlet tubulation supplies a flow of air across the window to inhibit deposit of combustion products thereon.
