Abstract
An ecology valve (EV) fuel return system is provided. In one embodiment, the EV fuel return system includes a housing assembly having a fuel return outlet and a first manifold inlet. The fuel return outlet is fluidly coupled to a fuel supply system, and the first manifold inlet is fluidly coupled to a first manifold of a gas turbine engine (GTE). An ecology valve is disposed in the housing assembly and fluidly coupled to the fuel return outlet and to the first manifold inlet. A fuel routing assembly is fluidly coupled between the first manifold inlet, the fuel return outlet, and the ecology valve. The fuel routing assembly routes fuel: (i) from the first manifold inlet to the ecology valve when the GTE is in a shut-down mode, and (ii) from the ecology valve to the fuel return outlet when the GTE is in an engine start mode.
