This paper provides a description of the fuel flexibility tests performed in:

• a gas turbine

• a high pressure combustion rig

• an atmospheric combustion rig

with the combustion system used in Siemens recently developed gas turbine SGT-750.

The gas turbine test campaign was run with natural gas blends with up to 50vol% nitrogen or 40vol% carbon dioxide. Ignition and engine starts with inert gas blends were also tested.

The fuel flexibility tests were continued in a single burner high pressure combustion rig. Both inert and reactive gas blends were tested. High concentrations of inert gases were tested at simulated cold ambient conditions (down to −60°C) at high and low loads. Reactive gases, such as ethane, propane, butane and hydrogen, were tested at high load operation. Also syngas blends were tested.

To simulate ignition at extreme arctic conditions an atmospheric rig test was performed with cold air supplied from evaporated liquid air.

The different gas fuel blends were run with low NOx emissions, often below 10 ppm, without water injection.

This paper includes description of the test setups and evaluation of the emissions and combustion stability for the tested gas blends.
