1. 6. Släckteknisk skillnad mellan mörkt och ljust släckpulver

   Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Karl-Magnus Larsson; [2018]
   Nyckelord :Släckpulver; Släckeffekt; ISO-9705; Pulversläckare; Extinguishing powder; Extinguishing effect; Powder extinguisher; Technology and Engineering;

   Sammanfattning : The purpose of the work was to investigate whether an extinguishing powder with a darker color other than white has an increased extinguishing effect when extinguishing a fire in an enclosure. In the experiments conducted, a conventional extinguishing powder was tested against a carbon black-dyed extinguishing powder with nitrogen or air as a propellant. LÄS MER

3. 7. Influence of Building Structure and Building Content on Residential Fires

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Hilco Hiemstra; [2016]
   Nyckelord :Residential fires; Building structure; Building content; Insulation; Technology and Engineering;

   Sammanfattning : In Europe, there are still a significant amount of residential fires. Particularly fires in the living room are a major threat to the occupants. Much research has been done to residential fires. LÄS MER

4. 8. Elevated Fires

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Kseniia Polukhina; [2016]
   Nyckelord :fire position; elevation; fire development; Technology and Engineering;

   Sammanfattning : The primary objective of the present study is to evaluate the effect of the fire source elevation on the main fire parameters, by implementing laboratory experiments. In modern Fire Safety Engineering practice, it is often assumed that fire always commences at the floor level. However, it is not always the case. LÄS MER

5. 9. Effects of Water Mist System on a Controlled Fire

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Jasper Ho; [2015]
   Nyckelord :Fire; water mist; simulation; experiment; extinguish; extinguishment; Technology and Engineering;

   Sammanfattning : Current legislation regarding implementation of water mist system(s) requires full scale testing specific to its intended use which involves extensive funding that discourages potential users. This motivates the desire for accurate water mist simulation. LÄS MER

7. 10. Brandrisker vid lägre syrehalter – Experiment i konkalorimetern

   Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Erik Linnå; Viktor Wahlström; [2014]
   Nyckelord :CACC; carbon dioxide; carbon monoxide; cone calorimeter; controlled atmosphere; fire risk; heat release; HRR; hypoxic air; mass loss rate; oxygen; particle board; time to ignition; brandrisk; effekt; effektutveckling; koldioxid; kolmonoxid; konkalorimeter; LTH; massavbrinningshastighet; spånskiva; syrehalt; tid till antändning; Technology and Engineering;

   Sammanfattning : This report has been conducted to examine the advantages and disadvantages of using an open system for experiments in the cone calorimeter with a vitiated air enclosure at low oxygen levels. Eight different experimental set-ups were conducted in which two were designed according to ISO 5660, i.e. the cone calorimeter in its standard configuration. LÄS MER
