1. Estimation of energy need for heating in single-family houses : A dissertation for the technology licentiate´s degree in statistics
Sammanfattning : .... LÄS MER
2. District heat production under different environmental and social cost scenarios
Sammanfattning : District heat production systems (DHSs) are normally designed to meet the heat demand of customers at a minimum cost whilst fulfilling local and national regulations. Various factors influence the choice of district heat production units in a minimum-cost system. LÄS MER
3. Computational Analysis of Gas Flow and Heat Transport Phenomena in Ducts Relevant for Fuel Cells
Sammanfattning : The thesis concerns modeling, simulation and numerical analysis of heat and mass transport, and fluid flow in ducts of both solid oxide fuel cells (SOFCs) and proton exchange membrane fuel cells (PEMFCs). The unique fuel cell boundary conditions (thermal, mass) for the flow ducts in fuel cells are identified and applied. LÄS MER
4. Borehole Thermal Energy Storage Systems for Storage of Industrial Excess Heat : Performance Evaluation and Modelling
Sammanfattning : Improving industrial energy efficiency is considered an important factor in reducing carbon dioxide emissions and counteract climate change. For many industrial companies in cold climates, heat generated at the site in summer will not be needed to fulfil the site heat demand during this time, and is thus removed to the outdoor air.

5. Lignin Extraction from Black Liquor - Properties of the Liquors and Sulphur Content in the Lignin
Sammanfattning : Kraft lignin isolated by precipitation can be considered as being a valuable renewable source of energy and material. Removing lignin from black liquor is also advantageous as it decreases the load on the recovery boiler, which is usually the limiting factor in the production of kraft pulp. LÄS MER
