    Nyckelord :CFD; combustion; NOx emission; flame shape; burner;

    Sammanfattning : For natural gas combustion, there is a large amount of experience in the gas turbine industry. However, much of the design work is based on costly combustion tests due to insufficient accuracy of existing prediction tools for data such as emissions and effects due to fuel composition. LÄS MER
