    1. Days of Combustion 2004 June 02 – 03, 2004 Concept and First Operational Experiences of a Directly Wood Particle Fired Gas Turbine

    2. Days of Combustion 2004 June 02 – 03, 2004 Overview state of the art concept of directly wood particle fired gas turbine emissions: CO, CnHm, NOx conclusions

    3. Days of Combustion 2004 June 02 – 03, 2004 State of the Art mostly by means of steam power plants (10 MWel & 20 MWtherm, 30 %) allotherm gasification and operation of gas engine (2 MWel & 4.5 MWtherm, 25 %)

    4. Days of Combustion 2004 June 02 – 03, 2004 Powerplant Size (fuel) costs prop. earnings prop. or degressive

    5. Days of Combustion 2004 June 02 – 03, 2004 Directly Wood Particle Fired Gas Turbine existing gas turbine combustion chamber ash separator fuel feeding system

    6. Days of Combustion 2004 June 02 – 03, 2004 Requirements & Concept main grid isolation small volumes solid fuels long residence times & mixing formation of NOx two-stage combustion: autothermal gasification & complete combustion

    7. Days of Combustion 2004 June 02 – 03, 2004 Combustion Chamber of the Institute pressure vessel: ? 600 mm x 1 750 mm thermal input: 200 – 700 kW operating pressure: up to 3 bar spec. heat release rate: 3.0 – 4.6 MW/m3 ash separator: axial cyclone

    8. Days of Combustion 2004 June 02 – 03, 2004 Sectional Drawing

    9. Days of Combustion 2004 June 02 – 03, 2004 Airflows

    10. Days of Combustion 2004 June 02 – 03, 2004 KHD T216

    11. Days of Combustion 2004 June 02 – 03, 2004 Pneumatic Fuel Feeding System

    12. Days of Combustion 2004 June 02 – 03, 2004 CO Emissions

    13. Days of Combustion 2004 June 02 – 03, 2004 CnHm Emissions

    14. Days of Combustion 2004 June 02 – 03, 2004 NOx Emissions

    15. Days of Combustion 2004 June 02 – 03, 2004 Conclusions cost effective powerplant complete combustion and low NOx emissions by two stage combustion chamber appropriate adjusting of air mass flows reliable operation of expander due to ash separator
