Abstract
Apparatus for igniting fuel in a combustor includes an injector having an electrostatic fuel atomization nozzle and an igniter. The injector produces an initial combustion process that ignites the main fuel supply from a fuel nozzle. Alternatively, a main fuel nozzle is provided which includes a plurality of electrostatic fuel nozzles disposed about a centrally located igniter. In one embodiment, the igniter is a laser igniter.
Claims18
A flame injector for initiating combustion of a main air/fuel supply to a combustor, comprising:
- a housing having a body with an orifice at an end thereof;
- an electrostatic nozzle connectable to a fuel supply, said nozzle disposed in said housing and that produces an electrostatically atomized fuel spray into said orifice;
- and an igniter disposed at said orifice to ignite said electrostatically atomized fuel spray;
- said igniter comprises two electrodes formed in said housing about an external surface of said body that defines said orifice, said electrodes being electrically insulated from each other.
