  2. 1. Fourier Transform Infrared Spectroscopy in Industrial Hygiene Applications : Assessment of Emissions from and Exposures in Wood Processing Industries

    Author : Urban Svedberg; Christer Edling; Bo Galle; Hans-Erik Högberg; Nils Plato; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; FTIR; Exposure; Emission; Saw mills; Wood pellets; Tracer gas; Monoterpenes; Hexanal; Carbon monoxide; Open path FTIR; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

    Abstract : This thesis evaluates the use of Fourier Transform Infrared Spectroscopy (FTIR) as an approach to the increasingly difficult air sampling challenges within the field of occupational and environmental hygiene. The application of FTIR is exemplified by the assessment of emissions from and exposures in the sawmill and pellet industries. READ MORE

  4. 2. Mitigating Off-Gassing and Self-Heating in Fuel Wood Pellets Storage : A Raw Materials Selection and Pre-Treatment Centred Approach

    Author : Workson Siwale; Jonas Berghel; Gunnar Henriksson; Michael Finell; Stefan Frodeson; Mani Sudhagar; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solid biofuels; densified biomass; heat generation; off-gas emissions; carbon monoxide; carbon dioxide; methane; fatty and resin acids; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : Wood pellets have become a preferred solid biomass fuel for heat and power generation due to their standardized nature, known properties, and consistent quality. However, pellets produced from fresh sawdust sometimes undergo self-heating and off-gassing during storage. This poses a challenge for their transportation and storage. READ MORE

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

    Author : Tomas Persson; Per Lundqvist; Simon Furbo; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pellet; pelleteldning; kamin; panna; solvärmesystem; varmvattenberedning; systemutformning; småhus; elbesparing; verkningsgrad; emissioner; rökgasförluster; skorstensförlust; diskmaskin; tvättmaskin; Thermal energy engineering;

    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

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

    Author : Kaung Myat Win; Rebei Bel Fdhila; Tomas Persson; Erik Dahlquist; Henrik Thunman; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood pellet; Heating; Combustion; boiler; stove; emissions; particulate matter; Energy- and Environmental Engineering; energi- och miljöteknik; 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.

  7. 5. SiC based field effect sensors and sensor systems for combustion control applications

    Author : Mike Andersson; Anita Lloyd Spetz; Udo Weimar; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SiC; Field Effect Sensors; Combustion Control; Other physics; Övrig fysik;

    Abstract : Increasing oil prices and concerns about global warming have reinforced the interest in biofuels for domestic and district heating, most commonly through combustion of solid biomass like wood logs, hog fuel and pellets. Combustion at non-optimal conditions can, however, lead to substantial emissions of noxious compounds like unburned hydrocarbons, carbon monoxide, and nitrogen oxides as well as the generation of soot.
