Combustion System Development for the SGT6-5000F - IGCC Hardware Description Nozzle & Basket Diffusion flame nozzle based on the design that successfully operated at the SGT6-3000E (formerly known as the W501D5) Dow Chemical Plaquemine site. Dual fuel design: Natural gas as startup & backup fuel, H 2 / Syngas as main fuel. Dilution is premixed into the fuel. Combustor basket is an improved Siemens diffusion flame basket design. The transition segment and downstream turbine hardware is the standard design, no change is necessary for IGCC. Page 8

DOE Advanced Power Systems goal is to conduct R&D for CO 2 sequestration ready coal-based power systems. Phase 1 Technologies identification, R&D Implementation Plan, conceptual designs Phase 2 Development and Validation of Component Technologies Phase 3 (Not yet awarded) GT-IGCC plant construction, validation / demonstration Completed Page 13

Technology infusion from the Advanced GT to FutureGen & 2010 GT will be realized. Page 14

15 5. Conclusions Siemens has extensive gas turbine operational experience with fuels for IGCC spanning several decades. The combustion development program for the SGT6-5000F engine is based on a proven IGCC combustor and fully rig tested to ensure all emissions and operational requirements can be meet with syngas and high hydrogen syngas fuels. Siemens in partnership with the DOE Advanced Hydrogen Turbine project is working on advanced hydrogen combustion technologies producing lower emissions while at the same time operating at higher gas turbine efficiencies for IGCC projects with carbon capture.
