  1. 1. Development of LPP-Burner for Industrial Gas Turbine Application

    Författare :Jonas Holmborn; Strömningsteknik; []
    Nyckelord :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;

    Sammanfattning : 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.

  3. 2. Black liquor gasification : burner characteristics and syngas cooling

    Författare :Mikael Risberg; Mats Lindblom; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : Black liquor gasification at high temperature is a promising alternative to the conventional recovery boiler process used in chemical pulp mills today. Compared to a conventional recovery boiler a black liquor gasifier can increase the total energy efficiency of a chemical pulp mill and produce a synthesis gas that can be used for production of motor fuel.

  5. 4. Numerical Study of Cellular Instability in Burner Stabilized Adiabatic Laminar Premixed Flames

    Författare :Jiangfei Yu; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Detailed Numerical Simulation; Cellular premixed flame; Hydrogen; Oxy-fuel; Heat-flux burner; Hydrodynamic instability; Diffusive-thermal instability; Nonlinear flame dynamics.;

    Sammanfattning : The thesis deals with experiments and numerical simulations of adiabatic laminar premixed flames anchored to a heat-flux burner using different mixtures under various operating conditions. The aim is to obtain a better understanding of cellular instability in heat-flux burner anchored flames. LÄS MER

  7. 5. Pressurized entrained-flow high temperature black liquor gasification : CFD based reactor scale-up method and spray burner characterization

    Författare :Magnus Marklund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Black liquor is an important by-product in the chemical kraft pulping process, which provides the paper mill with pulp. Due to both economical and environmental protection driving forces it is important to recover the pulping chemicals and energy contained in the black liquor. LÄS MER
