ABSTRACT:
A system for cooling at least one gas turbine liquid fuel component located in a high temperature environment to eliminate coking in the component is disclosed. The system includes a sleeve surrounding the liquid fuel component, a device for providing a current of cool air, and a conduit connected between the cool air device and the sleeve to direct the current of cool air into the sleeve to cool the liquid fuel component. The system can also include a manifold connected to the conduit and a plurality of second conduits for connecting the manifold to a plurality of sleeves surrounding a plurality of liquid fuel components, each sleeve being connected to a corresponding second conduit. Each sleeve includes a plurality of spacing devices for centering the sleeve around the at least one liquid fuel component so as to form an annulus between the sleeve and the liquid fuel component through which the current of cool air flows. The system can alternatively use a supply of cool liquid pumped by a pump through a conduit adjacent to a liquid fuel component to cool the component.
