  4. 3. Discribing the Auto-Ignition Quality of Fuels in HCCI Engines

    Författare :Per Risberg; David E. Foster; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Auto-Ignition Quality; RON; MON; Cetane Number; HCCI; CAI and Fuels; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : The Homogeneous Charge Compression Ignition (HCCI) engine is a promising engine concept that emits low concentrations of NOx and particulates and still has a high efficiency. Since the charge is auto-ignited, the auto-ignition quality of the fuel is of major importance. LÄS MER

  5. 4. 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.
