A cap () may be connected to guide tube (). Cap () defines an access passageway () to the igniter rod. Structure () is arranged to reduce a range of radial movement of igniter rod () in the access passageway.

Gas turbine igniter with structure to reduce radial movement of igniter rod

A fuel injecting assembly for a combustor of a gas turbine engine has a gas supply structure, steam supply structure and oil fuel nozzle that are substantially separated to allow relative movement between a respective end section, end portion and end part due to thermal expansion and contraction.
