Abstract
A torch ignitor system provides a continuous flame to ignite fuel within a combustor of a gas turbine engine. The torch ignitor system includes a manifold and a plurality of torch nozzles to enable the flame or torch to simultaneously ignite multiple fuel nozzles within the combustor of the gas turbine engine.
Claims10
A torch ignitor system comprising:
- a torch ignitor comprising:
- a housing;
- a plurality of hot surface ignitors coupled to the housing;
- a fuel inlet coupled to the housing, wherein the fuel inlet provides a flow path for fuel to enter the housing;
- and
- an air inlet positioned within the housing, wherein the air inlet provides a flow path for air to enter the housing and mix with the fuel entering the housing to create a fuel and air mixture;
- wherein the plurality of hot surface ignitors are configured to ignite the fuel and air mixture to create an ignited fuel and air mixture;
- and
- a combustion chamber positioned between and fluidly coupling the torch ignitor to an annular manifold, wherein the combustion chamber includes a hollow center portion to allow the ignited fuel and air mixture to flow to the annular manifold and wherein the annular manifold has a circular cross-section such that the annular manifold is a torus shaped manifold and the annular manifold includes tubular walls such that an interior of the annular manifold is hollow to allow the ignited fuel and air mixture to flow through the annular manifold;
- wherein the annular manifold includes a plurality of torch nozzles extending from the annular manifold for expelling the ignited fuel and air mixture, wherein the plurality of torch nozzles are spaced around an outer wall of the annular manifold.
