SYSTEM AND METHOD FOR PURGING A FUEL MANIFOLD OF A GAS TURBINE ENGINE USING A FLOW DIVIDER ASSEMBLY

SYSTEM AND METHOD FOR PURGING A FUEL MANIFOLD OF A GAS TURBINE ENGINE USING A FLOW DIVIDER ASSEMBLY

A method of operating a gas turbine engine (10) in a low-power condition includes supplying fuel to the combustor (16) by supplying fuel to the first fuel manifold (62A) via a first flow divider valve (166A) and supplying fuel to the second fuel manifold (62B) via a second flow divider valve (166B)....

Zusammenfassung:A method of operating a gas turbine engine (10) in a low-power condition includes supplying fuel to the combustor (16) by supplying fuel to the first fuel manifold (62A) via a first flow divider valve (166A) and supplying fuel to the second fuel manifold (62B) via a second flow divider valve (166B). While supplying fuel to the combustor (16) by supplying fuel to the first fuel manifold (62A), the method includes stopping supplying fuel to the second fuel manifold (62B) and supplying pressurized gas to the second fuel manifold (62B) via the second flow divider valve (166B) to flush fuel in the second fuel manifold (62B) into the combustor (16) and hinder coking in the second fuel manifold (62B) and associated nozzles.
