Abstract
This invention relates to an apparatus and method for increasing the reactivity of a fuel/air mixture prior to homogenous combustion of the mixture. More specifically, this invention is a pilot for a gas turbine combustor which utilizes the heat of combustion within the pilot to increase the reactivity of a portion of the fuel/air mixture utilized by the pilot.
Claims6
A method for enhancing a first fuel/air mixture so that when said first fuel/air mixture is added to a second fuel/air mixture said second fuel/air mixture will combust with greater stability, said method comprising:
- generating said first fuel/air mixture,
- introducing said first fuel/air mixture to a non-catalytic centerbody via an entrance defined by said centerbody,
- expelling said first fuel/air mixture from said centerbody through a plurality of exits defined by said centerbody, and
- heating said centerbody using the heat of combustion of said second fuel/air mixture.
A pilot comprising:
- a flow conditioner,
- a centerbody positioned within the flow conditioner, said centerbody being non-catalytic material, and said centerbody having an entrance and multiple exits defined by said centerbody, and
- a pilot wall, said flow conditioner connected to said pilot wall at one end and said centerbody at a second end.
