The cracks have developed following repairs using a different welding process. Excessive cracking of the turbine exhaust duct could lead to reduction gearbox separation and/orAircraft Gas Turbine Engine Exhaust Section | Aircraft SystemsThe exhaust cone assembly consists of an outer shell or duct, an inner cone, three or four radial hollow struts or fins, and the necessary number of tie rods to aid the struts in supporting the inner cone from the outer duct. The outer shell or duct is usually made of stainless steel and is attached to the rear flange of the turbine case.Estimated Reading Time: 5 mins
Aircraft Turbine Engine Combustion Section Inspection gas turbine exhaust duct cracking Assembling
Exhaust Section The exhaust section of the turbine engine is susceptible to heat cracking. This section must be thoroughly inspected along with the inspection the combustion section and turbine section of the engine. Inspect the exhaust cone and exhaust nozzle for cracks, Are there cracks in the hot section of a turbine engine?One of the most frequent discrepancies that are detected while inspecting the hot section of a turbine engine is cracking. These cracks may occur in many forms, and the only way to determine that they are within acceptable limits or if they are allowed at all, is to refer to the applicable engine manufacturers service and overhaul manuals.See all results for this questionCan a gas turbine exhaust system get no respect?You dont have to visit many generating facilities powered by gas turbines (GTs) or attend many user-group meetings to realize that exhaust systems get little or no respect.See all results for this question

How to inspect, replace GT exhaust system components
5. Check exhaust-frame strut airfoils for cracking and leakage. 6. Inspect diffuser turning vanes and struts for cracks. 7. Check the diffuser for circumferential cracking. 8. Inspect exhaust frame for flange deformation. 9. Verify instrumentation (exhaust thermocouples, vibration detectors, etc) is Integrating Gas Turbines with Cracking Heaters in B. Gas Turbine Integration with Cracking Furnace When the heaters are integrated with gas turbine exhaust (TEG) as the primary source of combustion air, the oxygen in the preheated air to the heaters is significantly lower, about 14-16 vol%, depending on the turbine model characteristics.Cited by: 3Page Count: 6File Size: 483KBAuthor: Reza Tahery, Seyed Abotorab Mousazadeh MoosaviProblems & solutions with expansion joints in gas 4.1.1. Cracking Gas turbine exhaust systems are subject to rapid temperature increases from ambient to operational; particularly fig 1A Hot To Hot designs. This operational characteristic creates a number of problems, particularly for the earlier designs of framework.
