Influence of Fuel Chemical Properties on Soot Emissions From Gas Turbine Combustors

Abstract

The influence of fuel composition on soot emissions from continuous flow combustors is examined. A study of the combustion characteristics of a wide range of present and potential aviation fuels suggests that smoke point provides a better indication of sooting tendency than does hydrogen content. It is concluded from this study that the best empirical relationship between fuel chemical composition and soot emissions is one which combines two fuel composition parameters — smoke point and naphthalene content — into a single parameter which is shown to correlate successfully soot emissions data acquired from several different fuels burning in a variety of gas turbine and model combustors.

Análisis exergo ambiental de la combustión en una turbina de gas

“…Un inconveniente de la cámara de combustión tuboanular, que comparte con configuraciones tubulares, es la necesidad de interconectores (tubos a través del fuego). Los motores equipados con cámaras de combustión tuboanular incluyen la Allison 501-K, el J73 y J79 GE, P & W J57 y J75, y el RR Avon, Conway, Olympus, Tyne y Spey (Chin, 1989). En comparación con el diseño anular, la cámara tuboanular tiene una ventaja importante, su uso se puede llevar a cabo con poco suministro de aire, utilizando sólo un pequeño segmento de la cámara del total que contenga uno o más revestimientos.…”
