  2. 2. Short term water heat storage studies of velocity and temperature fields and their importance for sizing of the storage

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Jan Dahl; Luleå tekniska universitet.; [1993]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Short term water heat storage's have been introduced in many district heating systems. The main reason for this is the possibilities opened by the storage for optimization of the generation of heat and electricity in combined heat and power plants. READ MORE

  3. 3. Development of an optimization model for the location of biofuel production plants

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Sylvain Leduc; Luleå tekniska universitet.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Abstract : First generation biofuels have not achieved the expected greenhouse gas emission savings and the production may in some cases compete with food production. Issued from non arable land and certified wood, the production of the second generation biofuels are more adapted to tackle those issues. READ MORE

  4. 4. Studies of the flow pattern in short term hot water storages

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Pascal Veber; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Abstract : This thesis relates to the study of thermally stratified hot water storages used in district heating systems and is an extension of the doctoral theses of Jan Dahl and Roger Hermansson. The thermal performance of a stratified water storage is reduced by different phenomena such as heat transfer to the surroundings and mixing between hot and cold water during the charging of the tank.
