3. Combustion System Development for the SGT6-5000F- IGCC Hardware Description

Nozzle & Basket • Diffusion flame nozzle based on the design thatsuccessfully operated at the SGT6-3000E(formerly known as the W501D5) Dow ChemicalPlaquemine site.

• Dual fuel design: Natural gas as startup & backupfuel, H2 / Syngas as main fuel.

• Dilution is premixed into the fuel.

• Combustor basket is an improved Siemensdiffusion flame basket design.

• The transition segment and downstream turbinehardware is the standard design, no change isnecessary for IGCC.

5. Conclusions

Siemens has extensive gas turbine operational experience with fuels forIGCC spanning several decades.

The combustion development program for the SGT6-5000F engine isbased on a proven IGCC combustor and fully rig tested to ensure allemissions and operational requirements can be meet with syngas andhigh hydrogen syngas fuels.

Siemens in partnership with the DOE Advanced Hydrogen Turbine projectis working on advanced hydrogen combustion technologies producinglower emissions while at the same time operating at higher gas turbineefficiencies for IGCC projects with carbon capture.
