Scientific Problems and Advances in Development and Investigation of GTU Combustors

The article outlines main stages in the development of a low emission combustor (LEC) for a GTE-110M gas turbine and the results obtained in the single-burner compartment on a test bench of full parameters. A list of necessary works for preparing tests of flame tubes on a test bench as part of a gas turbine is presented. Potential risks include the following: overheating in individual sections of the metal walls of the flame tubes, excess pressure losses on the fuel lines, deviation from the given diagram of the temperature field at the turbine inlet, lack of ignition of individual flame tubes, occurrence of pressure fluctuations with high amplitudes, etc. The ways to eliminate the risks are suggested. Crucial imported components that require replacement with domestic counterparts are considered.
