The purging of residual fuel in gas turbine combustor fuel injectors is disclosed in which the fuel injector includes a fuel element having a first and second fuel passage for discharging the fuel to the combustor of the gas turbine. Upon interruption of the fuel to the fuel element, high pressure air is passed through an air passage to the first fuel passage to force the fuel in the reverse direction through the first fuel passage, through the second fuel passage, and discharge the residual fuel in each of the passages to the combustor through the second fuel passage.

[ We claim:] [1.] Fluid spray apparatus comprising:an element having first and second fluid passages for conveying a first fluid therethrough, said first and second fluid passages each having a discharge office adjacent an end of the element for discharging a spray of said first fluid, and inlet at a location spaced from said end for receiving the first fluid from a first fluid supply source;a passage for a second fluid in said element communicating with said first first fluid passage to communicate a high pressure second fluid to said first first fluid passage to purge the residual first fluid from said first and second first fluid passages through the discharge orifice of said second first fluid passage when the supply of first fluid to said first and second first fluid passages is interrupted;said element having a longitudinal axis; andsaid discharge orifices of said first and second first fluid passages are spaced from said longitudinal axis by substantially the same distance for each.
