GT-16 Gas Turbine Low-Emission Combustor: Results of Tests in a Single-Burner Chamber on the Stagnation Property Test Facility

This paper presents the comprehensive test results of gas turbine unit (GTU-16P) experimental low-emission combustor (LEC) investigations at pressures up to 2000 kPa and a wide range of ambient temperatures within the ±25°C. The technical solutions applied provided the transition and operation in low-emission modes with automatic control of the LEC fuel channels without pulsations. The emission test results confirmed the high combustion efficiency of fuel in the entire operating range and low emission of carbon and nitrogen oxides at GTU loads from 70 to 100% in accordance with the technical assignment requirements. A system for automatic control of LEC fuel valves depending on the load was developed and implemented, including the protection with transition to safe modes during pressure pulsations with amplitudes exceeding the permissible level.
