Development of the Advanced EV (AEV) burner for the ABB GTX100 gas turbine

The Advanced EV is a further improvement in the application of lean premix gas turbine combustion technology. Its development benefited from the broad experience in lean premix combustion with EV type burners at ABB. The AEV-burner was extensively tested using highly sophisticated experimental tools, like laser optical methods. In consequence very low NO,-values were achieved during the high pressure tests. The burner has been running at single digit NO, down to below 50% gas turbine load conditions. With the improved gas pilot system the burner can be operated safely and with low emissions down to idle conditions. Compared with other lean premix burners the AEV exhibits several advantages: - robust and simple design - simple oil and gas injection - robust against flame flashback - high flame stability - wide low NO operation range - Dry-Low-NOx capability for liquid fuels.
