  1. 1. On Heat and Paper From Hot Pressing to Impulse Technology

    University dissertation from Stockholm : Fiber- och polymerteknologi

    Author : Marco Francesco Carlo Lucisano; [2002]
    Keywords : Paper; Impulse Drying; Heat Transfer; Phase Change; Heat-Pipe Effect; Delamination; Flashing;

    Abstract : Impulse technology is a process in which water is removedfrom a wet paper web by the combined action of mechanicalpressure and intense heat. This results in increased dewateringrates, increased smoothness on the roll side of the sheet, andincreased density. READ MORE

  2. 2. District heating in future Europe : Modelling expansion potentials and mapping heat synergy regions

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Urban Persson; Sven Werner; Lars J. Nilsson; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; district heating; energy efficiency; distribution capital cost; heat demand density; plot ratio; excess heat recovery; sequential energy supply; heat utilisation rate; effective width;

    Abstract : This thesis presents a set of methodologies and approaches to investigate and determine the extent by which district heating can contribute to improved energy system efficiency and reduced carbon dioxide emissions in future Europe. The main motivation for suggesting large-scale implementation of district heating as a structural energy efficiency measure to obtain these objectives originates essentially in the predicament that a majority of European buildings today remain highly dependent on fossil fuels to provide energy needed for space heating and hot water preparation.

  3. 3. Realise the Potential! Cost Effective and Energy Efficient District Heating in European Urban Areas

    University dissertation from Gothenburg : Chalmers University of Technology

    Author : Urban Persson; Sven Werner; Louise Trygg; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; energy efficiency; distribution capital cost; heat density; plot ratio; excess heat recovery; sequential energy supply; heat utilisation; effective width;

    Abstract : The Member States of EU27 need to accelerate the integration of energy efficient technology solutions to reach the 20% energy efficiency target set for 2020. At current pace, projections indicate that only half of expected primary energy reductions will be reached. READ MORE
