Abstract:
A method for reducing an amount of carbon monoxide and hydrocarbon emissions and smoke from a gas turbine combustor using a splitter extension, the combustor including a pilot fuel injector, a baseline air blast pilot splitter including a convergent portion, and a center body, the convergent portion extending downstream to an end, the splitter extension including a divergent upstream portion, a divergent downstream portion, and a convergent intermediate portion extending between the upstream portion and the downstream portion, the upstream portion having a first diameter and attached to the baseline air blast pilot splitter, the downstream portion having a second diameter, said method comprising the steps of:injecting fuel into the combustor; and directing airflow into the combustor such that the airflow passes through the baseline air blast splitter into the splitter extension attached to the end of the baseline air blast splitter convergent portion.
