Practical Conclusions on GAS TURBINE SPRAY NOZZLES

ACHIEVEMENT of a high degree of atomization and evenness of distribution - particularly at low fuel rates-are major needs in the field of gas turbine powerplant fuel spray nozzles.

Since the swirl type of nozzle is inadequate to meet these needs, according to the authors, it is being abandoned in favor of duplex nozzles, which have the advantage of holding up the energy of atomization at low deliveries.

The duplex nozzle is also easy to manufacture and has a wide available range of fuel flows, compared with the simplex nozzle.
