  2. 11. On Gas Turbine Diagnostics with Emphasis on Combustion Chambers

    Author : Raik Orbay; Kraftverksteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulent combustion; PDA; swirl stabilisation; PIV; off-design.; Gas turbine; experimental methods; LDA; atomisation; emission measurements;

    Abstract : The thesis aims to analyse the gas turbine based energy conversion systems with the emphasis on combustion chambers. The investigation is mainly experimental at a component level. The majority of investigations concentrate on gaseous fuel firing. READ MORE

  4. 12. Experimental investigation of flows related to gas turbine combustion

    Author : Dragan Stankovic; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical engineering; combusiton; flameless; jets in cross flow; chemiluminescence; POD; LIF; PIV; Spray; Gas Turbine; single digit NOx; Premixed Combustion; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Abstract : The notion of "global warming" has become a major public-domain concept as an environmental threat to our future on earth. Independently of the accuracy of existing prediction of combustion emissions on the climate on earth, the concept of reducing combustion emissions has been an important political driving force in imposing more and more severe restrictions on harmful emissions from combustion.

  5. 13. Aspects of creep-fatigue in gas turbine hot parts

    Author : Magnus Hasselqvist; Gunnar Härkegård; Linköpings universitet; []
    Keywords : creep; fatigue; TMF; gas turbine; modelling; life assessment; ageing; micro-structure; solute drag; back stress; Haynes 230; IN792;

    Abstract : The goal is reliable creep-fatigue lifing methodology for industrial gas turbines.A literature study on high temperature materials used in gas turbines reveals that:• Most testing/modelling work has focused on characterisation and modelling of material response in isothermal standard tests, i.e. creep, tensile and LCF tests.

  6. 14. Numerical Modeling of Flows Related to Gas Turbine Combustors

    Author : Robert-Zoltán Szász; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasma; fluid dynamics; plasmas; Gaser; fluiddynamik; Gases; vortex breakdown; swirl; CFD; gas turbine;

    Abstract : The thesis focuses on the numerical simulation of the flow field in gas turbine burners. Due to tougher and tougher requirements on low levels of emission of pollutants there is a need for new combustion technologies. In gas turbines one method to attain low pollutant levels is the use of lean premixed combustion. READ MORE

  7. 15. Development of LPP-Burner for Industrial Gas Turbine Application

    Author : Jonas Holmborn; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; Dry Low Emission DLE ; Lean Partially Premix LPP ; Combustion; Gas Turbine; Burner; applied thermodynamics; Termisk teknik; termodynamik;

    Abstract : This thesis reports the work done in the development of a modified Lean Premix Prevaporised (LPP) burner for the use in Alstom Power Sweden’s industrial gas turbines. Incentive for the development of the modified burner have been the need to increase the flame stability over the operating range for the burner, especially for the liquid fuel but also the gaseous fuel operation.
