En fallstudie på SSAB EMEA i Borlänge
… heat within the industrial enterprise. Since then, SSAB has contributed to the heating of the residences that are connected to the local district heating network. The present study aims to examine the values that the utilization of waste heat add to the industrial company and …
tekniska, ekonomiska och miljömässiga förutsättningar för fjärrvärmeproduktion med lokalt skogsbränsle
A third party access to district heating networks has been proposed in Sweden, to increase the competition on the district heating market. Such third party access could create opportunities for the agricultural sector as an energy producer. This study describes the technical …

… changed because of today's rising electricity rates resulting in increasing heating costs for properties, especially in the properties with electric heating systems. "Ankaret" is a parish for "Svenska Alliansmissionen", which is located at "Gullbrannagården".The parish has …
… stringent energy requirements across Europe. When conventional district heating technology is used in areas with low energy consumption heatlosses do not fall even though the amount of energy delivered is reduced. This reduces income for thedistrict heating company. To maintain …
Där värme- och elproduktion samt lönsamhet studeras och avfall är huvudbränslet
The demand for district heating is expected to decrease in the future, due to competition from heat pumps and energy efficiency measures in buildings. Development of existing district heating systems is therefore necessary for district heating companies to maintain market …
… to examine how energy efficiency within this sector could affect the district heating volume in the future, on basis of Vattenfalls district heating system in Uppsala. An Excel model has been created to study how energy effficiency measures affects district heating demand in …
… electricity and oil prices it becomes interesting to calculate on alternative heating systems. I have chosen to calculate upon my parents? farm, which today heats the dwelling house with wood. This is very time-consuming work, time which could be spent on other work. The main …
The aim of this report was to do a case study at a geothermal heating system which has been in operation for about 5 years, and study if its performance has changed during this period of time. A literature study about the processes involved was also done in purpose of background …
… to look at the possibilities to start selling hot water from a small district heating plant with bioenergy. My reason for doing this project is to look at a new business opportunity for our farm. Our company have less work during the winter time compared to the spring and this …
… municipalities, mostly due to high emission from buildings with older wood heating furnace without hydraulic accumulator. In Vänersborg three areas were analysed in VEDAIR for the year 2003: Vargön, Mariedal and the downtown district. In the whole municipality the upper …
fastställande av fjärrvärmedistributionens läckage inom Vattenfall Värme Uppsala AB
Heat is distributed to the district heating customers through pipes with water as a heat carrier. The district heating system is complex. To decide what is leakages from the district heating net versus what is the water consumption of the plant, is difficult. Therefore, the …
A problem in the field of district heating is the oil burners needed to provide power when a peak load occurs. One possible way of reducing the needed amount of oil is to reduce the power demand for space heating in the district-heating substations when the need for district …
… problem with electrical vehicles is their lack of waste heat for compartmental heating, due to higher efficiency of the electrical engine and the fact that the energy conversion doesn’t involve combustion. An ordinary diesel-buss can use the waste heat from the engine for …
