    Abstract: PROBLEM TO BE SOLVED: To facilitate the replacement of sensor parts by providing a long conduit passing through the inside of an injector, and providing the conduit with an opening part for enabling the work from outside, and providing the opening part with at least one sensor for sensing the condition of the predetermined position of the inside of injector. SOLUTION: In a premixing type fuel injector 10 for gas turbine engine during the operation, the primary air is flowed into a mixing chamber 34a in the tangent direction through intake slots 32a, 32b, and the primary fuel joins the primary air through a primary fuel injection hole 40. The air-fuel mixture enters a combustion chamber 62, and ignited for combustion. At the same time, the secondary fuel and the secondary air are flowed into the combustion chamber 62 through a secondary fuel-air injection insert 52. The injector 10 is provided with a conduit 70 continuously extended in the nearly longitudinal direction so as to monitor the temperature of the predetermined position 68 near the rear end of the mixing chamber 34a, and a sensor probe is inserted for set from an opening part 74 of the conduit 70 for insertion.

    Abstract: A premixing fuel injector for a turbine engine includes easily replaceable means for monitoring temperature or other conditions of interest in the interior of the injector. The fuel injector includes a guide conduit (70) that penetrates into the injector's interior and has an externally accessible opening (74) for receiving a sensor probe (88). The probe carries at least one sensor, such as a thermocouple junction (106), for monitoring temperature or other conditions inside the injector. In one embodiment, the guide conduit has a nonlinear shape and the probe shank (92) is sufficiently flexible to follow the contour of the conduit and sufficiently rigid to overcome any insertion resistance that the conduit might offer. The flexibility of the shank (92) may vary longitudinally to enhance insertability of the probe into the conduit. The probe is longitudinally oversized relative to the conduit so that when the probe is correctly installed, a sensor element positioned at the probe tip (93) contacts the closed, distal end (84) of the conduit to improve the sensor's responsiveness to changing conditions inside the injector. The probe shank may also buckle slightly and press against the internal sidewall of the conduit to prevent excessive shank vibration.
