  1. TASK 73-13-41-990-501 Fuel Nozzle And Support Assembly - Description And Operation of the Fuel Nozzles

    1. Description

      1. The fuel nozzle and support assembly is a single tube design contained by fairings. Refer to Figure.

      2. There are 20 fuel nozzles in groups of two. They are externally installed through ports in the diffuser case. The fuel nozzles are bolted at the mounting flange to cast pads on the case.

        NOTE

        A seal prevents air leakage around the mounting flange.

    2. The fuel nozzle is a single orifice air blast design. The nozzle mixes air with fuel to get a fuel spray (atomization). Each nozzle will flow 13 to 600 pph (5,90 to 272,16 kg/hr). You can remove the inlet strainer element and the metering plug through the fuel inlet fitting. Refer to Figure.
