1. Black liquor gasification : burner characteristics and syngas cooling
Sammanfattning : Black liquor gasification at high temperature is a promising alternative to the conventional recovery boiler process used in chemical pulp mills today. Compared to a conventional recovery boiler a black liquor gasifier can increase the total energy efficiency of a chemical pulp mill and produce a synthesis gas that can be used for production of motor fuel.

2. Entrained flow gasification of biomass : On atomisation, transport processes and gasification reactions
Sammanfattning : Since the energy consumption in the world is increasing together with an increase of greenhouse gas emission it is of importance to find alternatives to fossil fuels. Biomass is one of the alternative energy sources which is both renewable and CO2 neutral. LÄS MER
3. Development of flue gas treatment for small-scale boilers with a focus on particulate matters purification
Sammanfattning : Small-scale boilers significantly contribute to particle matter (PM) emissions, which adversely affect health and global warming. According to World Health Organization, particulate matter was ranked as the fifth significant parameter in premature death in 2015. LÄS MER
4. The indoor thermal climate in residential buildings after energy efficiency measures in a subarctic climate
Sammanfattning : There is ongoing work related to the energy efficiency of residential buildings in the subarctic regions in northern Sweden. The focus is often on the reduction of energy usage and the economic aspects for the property owners. With the introduction of new technology and changes to the existing building, the indoor thermal climate is affected. LÄS MER
5. Thermal comfort and energy in residential buildings in a cold climate
Sammanfattning : Building design typically has a focus on energy use and economy. The indoor environment is often overlooked or simplified to such an extent that essential aspects are neglected. Additionally, introducing technologies for improving energy efficiency can also affect the indoor thermal climate and, in turn, the perceived indoor comfort. LÄS MER
