  1. 1. Particle emissions from wood pellet combustion

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Henrik Wiinikka; Luleå tekniska universitet.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Abstract : Combustion of solid biomass under fixed bed conditions is a common technique to generate heat and power in both small and large scale grate furnaces (domestic boilers, stoves, district heating plants). Unfortunately, combustion of biomass will generate particle emissions containing both large fly ash particles and fine particles that consist of fly ash and soot. READ MORE

  2. 2. Improving Wood Fuel Pellets for Household Use Perspectives on Quality, Efficiency and Environment

    University dissertation from Karlstad : Karlstads universitet

    Author : Magnus Ståhl; Karlstads universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood fuel pellets; sawdust; drying; pellet production; recirculation; quality; efficency; environment; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : Bioenergy is one of many contributors to reducing the use of fossil fuels in order to mitigate climate change by decreasing CO2-emissions, and the potential for biofuels are large. The wood fuel pellets are a refined biofuel made of sawdust, which is dried and compressed to achieve improved fuel and transportation properties. READ MORE

  3. 3. Combined solar and pellet heating systems for single-family houses how to achieve decreased electricity usage, increased system efficiency and increased solar gains

    University dissertation from Stockholm : KTH

    Abstract : In Sweden, there are about 0.5 million single-family houses that are heated by electricity alone, and rising electricity costs force the conversion to other heating sources such as heat pumps and wood pellet heating systems. Pellet heating systems for single-family houses are currently a strongly growing market. READ MORE

  4. 4. Emissions from realistic operation of residential wood pellets heating systems

    University dissertation from Västerås : Mälardalen University

    Author : Kaung Myat Win; Mälardalens högskola.; Högskolan Dalarna.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik; Wood pellet; Heating; Combustion; boiler; stove; emissions; particulate matter; SWX-Energi; Integrerade system för sol och biobränsle;

    Abstract : Emissions from residential combustion appliances vary significantly depending on the firing behaviours and combustion conditions, in addition to combustion technologies and fuel quality. Although wood pellet combustion in residential heating boilers is efficient, the combustion conditions during start-up and stop phases are not optimal and produce significantly high emissions such as carbon monoxide and hydrocarbon from incomplete combustion.

  5. 5. Wood Fuel Pellets: Sawdust Drying in the Energy System

    University dissertation from Karlstad

    Author : Magnus Ståhl; Karlstads universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood fuel pellets; sawdust; drying; pellet production; recirculation; VOC; system integration; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : In 2004, the amount of wood fuel pellets used in Sweden was 1 256 000 tons, it was mostly used in large scale burning for district heating. Over the last 10 years, a significant increase in pellet production has occurred and today the preferred raw materials for pellet production, i.e., dry sawdust and wood shavings, are insufficient.
