Abstract
A fuel leakage protection system is disclosed for a gas turbine engine having a fuel system that has a plurality of fuel nozzles that are spaced around a combustor section, a plurality of fuel tubes that are connected to the fuel nozzles individually, two generally semi-circular fuel manifolds that are located aft of the fuel nozzles and that ar connected to the fuel tubes and a branch manifold that is connected to the fuel manifolds. The fuel leakage protection system comprises a collar assembly encapsulating each fuel supply fitting connecting a fuel tube to a fuel nozzle or the branch manifold to a fuel manifold to trap leakage fuel. A fuel collection manifold collects leakage fuel from the collar assemblies via a plurality of fuel return tubes that are connected to the manifold at one end and fluidly connected to the collar assemblies at the other end. The fuel collection manifold also has a fitting that fluidly connects the fuel collection manifold to an evacuation line that leads to a collector that is located remote from the combustor section.
