  1. 11. Dynamics of large-scale fluidized bed combustion plants

    Författare :Guillermo Martinez Castilla; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operational flexibility; combined heat and power; process control; thermal power plant; biomass combustion;

    Sammanfattning : Fluidized bed combustion (FBC) plants are widely used in energy systems across the world for the thermochemical conversion of solid fuels, and are especially suitable for low-rank fuels (a category to which renewable solid fuels belong). FBC plants are traditionally operated for base-load electricity production and for heat production, both of which processes are characterized by steady and stable operation. LÄS MER

  3. 12. Robotized Production Methods for Special Electric Machines

    Författare :Erik Hultman; Mats Leijon; Jörg Franke; Uppsala universitet; []
    Nyckelord :Industrial robotics; Assembly automation; Large-scale production; Cable winding; Linear generator; Wave energy converter; Wave power; Engineering education; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : A research project on renewable energy conversion from ocean waves to electricity was started at the Division of Electricity at Uppsala University (UU) in 2001. The Wave Energy Converter (WEC) unit developed in this project is intended to be used in large offshore WEC farms and has therefore been designed with large-scale production in mind. LÄS MER

  4. 13. Large scale experiments and modeling of black liquor gasification

    Författare :Per Carlsson; Mikko Hupa; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : Biomass gasification could provide a basis for increased electricity and engine fuel production from a renewable source in the pulp and paper industry. This work focuses on the largest byproduct available at the pulp mills, black liquor. LÄS MER

  5. 14. Models and solution methods for large-scale industrial mixed integer programming problems

    Författare :David Bredström; Mikael Rönnqvist; Dag Wedelin; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematic; linear programming MIP ; production-planning; MATHEMATICS; MATEMATIK;

    Sammanfattning : This thesis deals with large-scale industrial problems that can be formulated using mixed integer linear programming (MIP) models. Because of the large problem size, it is not often possible to apply standard solution methods. Therefore special techniques must be used. LÄS MER

  7. 15. Distributed Stochastic Programming with Applications to Large-Scale Hydropower Operations

    Författare :Martin Biel; Mikael Johansson; Stein W. Wallace; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Stochastic programming is a subfield of mathematical programming concerned with optimization problems subjected to uncertainty. Many engineering problems with random elements can be accurately modeled as a stochastic program. In particular, decision problems associated with hydropower operations motivate the application of stochastic programming. LÄS MER
