The first phase high pressure oxy-fuel combustion testing in the Gassnova funded OXYGT project (www.gassnova.no) has been successfully achieved. The adapted gas turbine burner has been run under extensive operating conditions and up to a pressure of 7 bar. The accumulated measurement results are now under processing.
The oxy-fuel gas turbine is the key component of a natural gas fired gas turbine combined cycle with CO2 capture, but is not mature yet due to large R&D effort needed to re-design all parts of the engine and particularly the combustor. The testing performed in relevant conditions represents a step forward in the understanding of burner and combustor behaviour in oxy-fuel mode.
