Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent …
Undersökning av ett nedlagt oljebergrum
This thesis considers the use of an oldrock cavern as thermal energy storage.With a large system of differentchillers a model was created to find anappropriate future system. There aremainly two trajectories to take. Eitheran installation of chillers needs to bemade or the rock …
Metoder för att sänka återledningstemperaturen
… with the local district heating system in Malå. The aim is to increase the thermal efficiency of the cogeneration plant in Malå, by lowering the temperature of the cooling medium. Another benefit that comes from this is improved combustion efficiency at the power plant, since …

Luossavaara-Kiirunavaara Aktiebolag (LKAB) är en gruvdriftskoncern med järnmalmsbrytning som huvudsaklig verksamhet. En av produkterna tas fram genom att raffinera järnmalm till pellets vilket är en efterfrågad produkt vid ståltillverkning. Vid sintring av råkulor till pellets …
Hjälpmedel vid beräkning av temperatursprickor i vanligt förekommande betongkonstruktioner.
Rapporten innehåller inledningsvis en faktadel med allmän information kring temperatursprickor i betong. Här presenteras bl a uppkomsten av fenomenet, vilka typer av sprickor som förekommer och vad ett tvång är. Tanken är att ge läsaren tillräcklig kunskap för att kunna förstå …
… new production capacity. Heat from the electricity production is loaded into thermal storages to cover a part of the future need for heat. Heat can also be rejected as surplus heat into water if the demand for electricity is high. Renewable biofuels turn CHP plants into …
technology of treatment and properties of modified wood
… anti-swelling efficiency (ASE) was in the range 40-57%. Reference samples of thermally modified wood showed only 40% ASE. The grafting of ELO to the wood polymeric constituents was studied using FT-IR spectroscopy. The modification influenced negatively the modulus of rupture …
