ABSTRACT:
A main flow divider valve for a main stage of a multi-stage combustor includes a cooling loop for flowing pilot fuel therethrough to remove heat from the main flow divider valve. Various construction details are disclosed which provide cooling of the main flow divider valve during pilot only operation of the multi-stage combustor. In a particular embodiment, the main flow divider valve includes a cooling loop disposed about a housing of the main flow divider valve. The cooling loop has an inlet in fluid communication with a first port of a relief valve and an outlet in fluid communication with the pilot fuel lines. The cooling loop receives a flow of pilot fuel during all operational conditions of the gas turbine engine.
