… been focused on verifying whether the existing structure provides sufficient heating and cooling functions. Based on the validation review, the current prototype's performance is presented and suggestions for improvements are submitted.Knowledge in the relevant area has been …
… there are several radio transmitters/receivers that takes space, generates heat and transmit in varied frequency band etcetera. All these radio transmitters/receivers could be replaced with a Software Defined Radio system. It means that one common, general radio hardware is used …
utveckling av en beräkningsmodell med simuleringsverktyget IPSEpro
Heat and power stations are often in need of optimizations. A simulation model is a tool for findingways to optimize the plant. The scope of this diploma work is to develop a simulation model ofBoiler 5 at Mälarenergi AB. Boiler 5 is a circulated fluidized bed boiler that was …
… Combustion engines are in need of a cooling system that reduces the heat developed during the combustion. In general, two main types of cooling systems are employed; either air cooling, where the outside of the cylinder is exposed to a flow of the surrounding air, ore water …
… the importance of well constructed details increases when minimizing the heat losses. Examples of these details are floor-wall junction and window openings in the wall. In such connections thermal bridges occur, which means that heat more easily is transported out of the …
ett Sex sigma <br /> projekt för analys och åtgärdsförslag på Sapa Heat Transfer AB
Detta examensarbete har utförts på Sapa Heat Transfer i Finspång och har tagit upp frågan med hur den interna hanteringen av produkterna kan orsaka defekter. I arbetet har en typ av defekt undersökts särskilt och denna defekt kan ses som ett exempel. Företaget tillverkar …
… ” into small drops. The drops are rapidly cooled in a water bath where all the heat energy from the liquid metal is transferred into the water. The granulation is often performed with great metal flows, normally 1-4 tonnes of metal is granulated per minute. The energy that is …
The purpose of this thesis for Sapa Heat Transfer is to examine a furnace in which aluminium is pre-heated before hot rolling. The project is modeled in a computer environment in which the air flow in the furnace and the heat transfer to the aluminium solids are included. The …
Undersökning av temperatur- och luftbeteende intill höga glasfasader och i vistelsezon med golvvärme som en värmekälla
… due to cold downdraught. Cold downdraught can be countered by placing heaters under glass surfaces. Nowadays technology offers highly insulating windows, which is why there is an interest to investigate the indoor climate with only underfloor heating. The research in this area …
Problem area Alfa Laval is a world leading company in the heat transfers area and have the vision to continue to be that in the future as well. The company has a lot of press lines where the utilization is high and also has started to become old. Prognosis shows that there is an …
panna 5, Mälarenergi AB, Västerås
During the past 30 years the fuels for energy production in heating and power plants have changed. Fossil fuels have decreased in usage whereas bio fuels in Sweden have increased with 60% since the 1970's. Different fuels affects combustion and the release of various substances …
… detta examensarbete har varit att genomföra en nulägesanalys av Hall 7 på Sapa Heat Transfer AB i Finspång. Utifrån nulägesanalysen togs åtgärdsförslag fram som kan generera en effektivare uppvärmning, mindre yttre utsläpp och behagligare arbetsklimat. Problemet i Hall 7 är att …
… has been created where input for different parameters such as insulation, heating and lighting can be varied. The model calculates the energy usage of the different parameters and then translates them into carbon dioxide emissions. The results show that the single parameter that …
A feasibility study
… low power consumption since they are close to the load, which is sensitive to heat. Different amplifier architectures were investigated to find a suitable circuit for the given prerequisites. In this report the advantages and disadvantages of voltage and current feedback are …
Idag värms glasugnar upp med antingen gasol eller olja, detta projekt vill visa på möjligheten att istället använda gas från biobränsleförgasning som förbränns utan synliga flammor. Detta skulle miljömässigt ge fördelarna att biobränslen inte bidrar till växthuseffekten och ge …
