The influence of changes in fuel calorific value to combustion performance for Siemens SGT-300 dry low emission combustion system

- Standard Siemens SGT-300-1S combustion hardware was tested in a high pressure rig.
- For gaseous fuel Wobble Index (WI) was tested from 23 to 49 MJ/m3.
- Standard engine operation fuel schedule can be used for WI higher than 27 MJ/m3.
- WI has significant impact on NOx emissions and low WI has benefit for NOx reduction.
- More NOx is produced if N2 is selected as diluent.
