Abstract
A hybrid ignitor including an ignitor body with an ignitor wall defining an ignitor interior and an ignitor exterior, the ignitor body having an electrode end opposite a discharge end; a central electrode disposed within the ignitor interior, the central electrode including a spark end; a ground electrode disposed within the ignitor interior and electrically coupled with the central electrode near the spark end; an air inlet formed in the ignitor wall near the spark end; and a solid fuel disposed within the ignitor interior near the discharge end and near the spark end of the central electrode and downstream of the air inlet.
Claims20
A hybrid ignitor comprising:
- an ignitor body with an ignitor wall defining an ignitor interior and an ignitor exterior, the ignitor body having an electrode end opposite a discharge end;
- a central electrode disposed within the ignitor interior, the central electrode including a spark end;
- a ground electrode disposed within the ignitor interior and electrically coupled with the central electrode near the spark end;
- an air inlet formed in the ignitor wall near the spark end;
- and
- a solid fuel disposed within the ignitor interior near the discharge end and near the spark end of the central electrode and downstream of the air inlet.
A gas turbine with a hybrid ignitor comprising:
- a case supporting a combustion section having a combustion chamber;
- an ignitor body attached to the case, the ignitor body comprising an ignitor wall defining an ignitor interior and an ignitor exterior, the ignitor body having an electrode end opposite a discharge end, the discharge end disposed within the combustion chamber;
- a central electrode disposed within the ignitor interior, the central electrode including a spark end;
- a ground electrode disposed within the ignitor interior and electrically coupled with the central electrode near the spark end;
- an air inlet formed in the ignitor wall near the spark end;
- and
- a solid fuel disposed within the ignitor interior near the discharge end and near the spark end of the central electrode and downstream of the air inlet.
A process of forming a gas turbine with a hybrid ignitor comprising:
- forming an ignitor body with an ignitor wall defining an ignitor interior and an ignitor exterior, the ignitor body having an electrode end opposite a discharge end;
- disposing a central electrode within the ignitor interior, the central electrode including a spark end;
- disposing a ground electrode within the ignitor interior and electrically coupling the ground electrode with the central electrode near the spark end;
- forming an air inlet in the ignitor wall near the spark end;
- and
- disposing a solid fuel within the ignitor interior near the discharge end and near the spark end of the central electrode and downstream of the air inlet.
