2. 1. 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

4. 2. Process Utility Performance Evaluation and Enhancements in the Traditional Sugar Cane Industry

   Author : Eyerusalem Deresse Birru; Andrew Martin; Catharina Erlich; Hailong Li; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sugar cane; energy saving; heat loss; steady state; transient state; CO2 emission; absorption chiller; pellet; bagasse drying; energy perfor-mance; traditional mills; modern mills; waste water; surplus power; Energy Technology; Energiteknik;

   Abstract : The need to achieve sustainable development has led to devising various approaches for the efficient utilization of natural resources. Renewable energy technology and energy efficiency measures feature prominently in this regard, and in particular for industries such as sugar production:  the sugar cane industry’s eponymous feedstock is a renewable resource, and mills have potential for increased energy savings via improvements to cogeneration units, electric drive retrofitting, and other measures.

5. 3. Particle emissions from wood pellet combustion

   Author : Henrik Wiinikka; Luleå tekniska universitet; []
   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

6. 4. Implication of pellet quality on combustion performance

   Author : Peter Sundberg; Claes Tullin; Sylvia Larsson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Abstract : Quality aspects of wood pellets and their use have been of utmost importance since the development of the pellet market in the early 1980s. Research and hard-earned knowledge have resulted in advancements in the field, but there are still uncertainties in the pellet industry about how different quality aspects affect combustion performance.

7. 5. 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.
