  1. 1. Regional Energy Systems with Retrofitted Combined Heat and Power (CHP) Plants

    University dissertation from Västerås : Mälardalen University

    Author : Song Han; Mälardalens högskola.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combined heat and power; Waste-to-Energy WtE ; Regional energy system; Greenhouse gases GHG ; Retrofitting; Optimization; Kraftvärme; Avfall-till-Energi; Regionala Energisystem; Växthusgaser; Uppgradering; Optimering.; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Fossil fuel depletion, economic development, urban expansion and climate change present tough challenges to municipal- and regional-scale energy systems. Regional energy system planning, including waste treatment, renewable energy supply, energy efficiency, and climate change, are considered essential to meet these challenges and move toward a sustainable society.

  2. 2. Retrofitting CHP Plant and Optimization of Regional Energy System

    University dissertation from Västerås : Mälardalen University

    Author : Song Han; Mälardalens högskola.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; annual performance; combined heat and power; drying; ethanol; integration; part-load.; årliga prestation; kraftvärme; torkning; etanol; integration; del-last.; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The use of biomass-based combined heat and power (CHP) plants is considered by the EU administration to be an effective way to increase the use of renewables in the energy system, to reduce greenhouse gas emissions and to alleviate the dependency on imported fossil fuels. At present in Sweden, most of the CHP plants are operated in part-load mode because of variations in heat demand. READ MORE

  3. 3. Integration of thermochemical processes with existing waste management industries to enhance biomethane production

    University dissertation from Västerås : Mälardalen University

    Author : Chaudhary Awais Salman; Mälardalens högskola.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polygeneration; process integration; integrated biorefineries; biomethane; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : In most waste management industries, waste is separated into different fractions, each of which is treated with suitable processes. Established technologies such as waste combustion for combined heat and power (CHP) production and biomethane production through anaerobic digestion (AD) of biodegradable waste work fine as standalone processes.

  4. 4. Economic and Environmental Benefits of CHP-based District Heating Systems in Sweden

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Shahnaz Amiri; Linköpings universitet.; Linköpings universitet.; Högskolan i Gävle.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Framtidens energisystem och därmed även klimatet påverkas av många faktorer, såsom energitillgångar, efterfrågan på energi, energipolicy och valet  av energitekniska lösningar. De framtida energisystemen står inför tre viktiga utmaningar: den ständigt växande efterfrågan på energi i världen, problemet med minskande energitillgångar samt den ökande koldioxidhalten i atmosfären och utsläppen av andra växthusgaser och deras påverkan på klimatförändring.

  5. 5. Restructured district heating price models and their impact on district heating users

    University dissertation from Västerås : Malardalen University

    Author : Jingjing Song; Mälardalens högskola.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating; restructured price model; price model survey; pricing strategy; consumption profile; consumption pattern; alternative cost; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : District heating (DH) is considered to be an efficient, environmentally friendly and cost-effective method for providing heat to buildings, since electricity is usually co-generated in biomass fuelled combined heat and power (CHP) plants. This gives it an important role in the mitigation of climate change. READ MORE
