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.
Claims40
An ignition system for use with a combustor comprising:
- means for providing a main air/fuel mixture to the combustor;
- a flame injector comprising an electrostatic nozzle for producing an electrostatically atomized fuel spray and an igniter, said nozzle and igniter being disposed in a common housing having an outlet that opens to the combustor;
- said igniter for igniting said atomized fuel spray from said nozzle at said outlet to produce a flame that extends beyond said housing into the combustor to ignite said main air/fuel mixture;
- and electrical energy means for providing electrical energy to said nozzle for controlling fuel atomization from said nozzle.
