    Model scale tunnel fire tests with water-based fire suppression systems2014Report (Refereed)
    Abstract [en]

    A total of 18 tests were carried out in the 1:4 model scale tunnels with water-based fire suppression systems together with one free-burn test. The key parameters including fuel load covers, activation time, water flow rate, nozzle type, ventilation velocity, sprinkler section length and tunnel width were tested. Technical information and analyses of test data are presented in this report with a focus on the influence of these different parameters on the design fire in a tunnel with a water-based fire suppression system. Further, guidance for the design fires in tunnels with water-based fire suppression systems is proposed.

    Model scale tunnel fire tests with automatic sprinkler2013In: Fire safety journal, ISSN 0379-7112, E-ISSN 1873-7226, Vol. 61, p. 298-313Article in journal (Refereed)
    Abstract [en]

    Abstract The study focuses on the performance of an automatic sprinkler system in a model scale tunnel with longitudinal ventilation. A total of 28 tests were carried out in a 1:15 model scale tunnel using an automatic sprinkler system with glass bulbs. The maximum heat release rate, energy content and failure of the automatic sprinkler system were analysed. The results show that high ventilation rates and low water flow rates result in a failure of the automatic sprinkler system in a longitudinal ventilated tunnel fire. The main reason for the failure under the tested water flow rates was the effect of the longitudinal flow on the fire development and the hot gas flow close to the sprinklers. The fire development and the activation heat release rate of the first activated bulb are intimately related to the ventilation velocity. The fire spread to the neighbouring wood crib was investigated and a presentation of tests conducted using a deluge system are given.

    Fire Test of Profile Plank for Transformer Pit Fire Protection2014In: Fire technology, ISSN 0015-2684, E-ISSN 1572-8099, Vol. 52, no 2, p. 309-319Article in journal (Refereed)
    Abstract [en]

    In general it is recommended to fill a transformer pit with rock ballast to extinguish the fire if there is a leakage of burning transformer oil. There is a lack of technology-neutral performance requirements for the design of solutions for fire extinguishment in transformer pit fires. This hampers the introduction of alternatives to the traditional method of filling the pit with rocks. Therefore we have conducted quantitative tests where temperatures and concentrations of CO, CO2, and O2 were measured at different position in a transformer pit subjected to burning oil simulating an accidental rupture and leakage. The tests were conducted to investigate the extinguishing capacity of one specific alternative solution, i.e. a profile plank layer over the pit. Three tests were performed with 90°C and 140°C pre-heated transformer oil. In the second test, a 19 cm water bed was used to examine the impact of rain water in the pit. The result showed that the profile plank extinguished the flames in a few seconds and that the water level did not have any significant effect on the result. The measurements showed that the temperatures peaked at 600–800°C 50 cm above the profile plank in all tests but dropped to under 100°C in 14–16 s. Furthermore the O2-concentration dropped to 3–5 vol% below the plank, which contributed to the rapid extinction of the burning oil.

    Use of small scale methods for assessments of risk for self-heating of biomass pellets2012Report (Refereed)
    Abstract [en]

    One major concern when it comes to storage of wood pellets is the risk for self-heating. The propensity for self-heating varies between different types of pellets. It also depends on how the pellets have been handled and on the storage conditions, e.g. the temperature and humidity. Within the framework of the research project “Large scale Utilization of Biopellets for Energy Applications –LUBA” different laboratory-scale methods have been used to study different thermal properties and the propensity for self-heating for different types of pellets. The different methods used include micro calorimetry also called isothermal calorimetry, basket-heating tests and transient plane source (TPS). In total 21 different pellets samples were tested in the micro calorimeter, three in the basket-heating test and three in the TPS. The samples showed significant differences in propensity for self-heating. Differences could be seen both between different types of pellets and depending on the age of the pellets. Comparing the reactivity rates from the basket-heating tests and those from the isothermal calorimetry tests with the same type of pellets, both methods gave the same ranking of reactivity. It was shown that the TPS-method is applicable for the determination of thermal properties both for measurements on single pellets and for measurement on bulk pellet material.

    Pulsations During Fires in Tunnels2013In: Fire technology, ISSN 0015-2684, E-ISSN 1572-8099, Vol. 49, no 2, p. 551-581Article in journal (Refereed)
    Abstract [en]

    The existing theoretical modelling of thermoacoustic oscillations has been studied and applied to the case of tunnel fires. The assumptions of the theoretical model were reviewed. It was found that several assumptions are not applicable to tunnel fires and, hence, suggestions for improvement are given. The correlation which expresses the starting conditions for thermoacoustic oscillations is analysed and dependencies on different parameters are presented. The pulsations documented during the large-scale tests in the Runehamar tunnel in 2003 have also been further analysed. The measurements were compared to the theoretical limiting curve for oscillations, showing good agreement. To further study thermoacoustic oscillations in tunnels, more detailed tests in a model-scale tunnel (1:100) were performed. These tests focused on the circumstances which are required to create thermoacoustic oscillations, i. e. the fire was located at different positions along the tunnel and the air flow rate was varied. The tunnel had a length of 4 m, was 8 cm wide and 6 cm high. The results were in good accordance with the theoretical modelling but showed deviations which were most obvious at very low and high air velocities. Both the starting conditions for thermoacoustic oscillations and cases where the thermoacoustic oscillations suddenly stopped, were observed. These findings led to identification of several points in the theoretical model which need to be improved, and to the development of a strategy to avoid such pulsation in fires.

    Pilot spark energy in the cone calorimeter: A source of measurement uncertainties2014In: Fire and Materials, ISSN 0308-0501, E-ISSN 1099-1018, Vol. 38, no 7, p. 760-764Article in journal (Refereed)
    Abstract [en]

    This work presents measurements meant to study the influence of the spark energy on the time to ignition of a given material in the cone calorimeter. For this purpose, square slabs of particle board were tested under two radiation intensities until ignition occurred using two spark energies for each intensity level. Results show that increasing the spark energy leads to a reduction inthe ignition time regardless of the radiation intensity. However, the influence of the spark energy on the time to ignition is, in absolute numbers, larger for the low radiation intensity case than for the high radiation intensity case. Nonetheless, the proportional difference is nearly 10% for both levels of heat radiation. Results from this work confirm that there is an influence of the spark energyon the time to ignition of a given material suggesting that a narrower and more specific definition of the ignition circuits allowed in the cone calorimeter would be highly beneficial for ensuring repeatable results among laboratories.

    Electrical currents and breakdown voltages as a diagnostic tool for fires2011Report (Refereed)
    Abstract [en]

    Two types of electrical measurements have been investigated in order to perform diagnostics of the fire dynamics in the ISO 5660 cone calorimeter. The rationale of the study is to take advantage of the pilot ignition electrodes that are already in place and use these to collect additional information such as emission of pyrolysis gases and time to ignition. The first part of the project was a refinement of the method for measuring the so called ion current, which has already been investigated in a pilot study. It was found that thorough shielding and grounding gives an excellent signal to noise ratio. An expression for the correlation between measured current and conductivity was also developed and validated experimentally. The second part of the project consisted of measuring the breakdown voltage, that is the voltage when dielectric failure occurs. It was found that this method was more sensitive to the fire dynamics before ignition, such as pyrolysis, but that the response to ignition was more ambiguous for the breakdown voltage than for the ion current.

    Measuring breakdown voltage for objectively detecting ignition in fire research2013In: Measurement science and technology, ISSN 0957-0233, E-ISSN 1361-6501, Vol. 24, no 10, article id 105802Article in journal (Refereed)
    Abstract [en]

    This paper presents a method intended for detecting the initiation of combustion and the presence of smoke in confined or open spaces by continuously applying an intermittent high-voltage pulse between the electrodes. The method is based on an electrical circuit which generates an electrical discharge measuring simultaneously the breakdown voltage between the electrodes. It has been successfully used for the detection of particle-laden aerosols and flames. However, measurements in this study showed that detecting pyrolysis products with this methodology is challenging and arduous. The method presented here is robust and exploits the necessity of having an ignition system which at the same time can automatically discern between clean air, flames or particle-laden aerosols and can be easily implemented in the existing cone calorimeter with very minor modifications.

    Detection of fires in the engine compartment of heavy duty vehicles, a theoretical study2014In: SAE 2014 World Congress and Exhibition;, 2014, Vol. 1, p. 423Conference paper (Other academic)
    Abstract [en]

    Fires in the engine compartments of surface and underground non-rail heavy duty vehicles are still highly frequent. Statistics show that most of the reported fires commenced in the engine compartment and that these were not promptly detected by the drivers. Fires which were not detected rapidly, spread oftentimes beyond the firewall of the engine compartment having notorious economical and environmental repercussions; furthermore, endangering the safety of the occupants. Detecting fires in the engine compartments of heavy duty (HD) vehicles with inexpensive and simple automatic detection systems is in general challenging. High air flows and large amounts of suspended pollutants, together with the complicated geometry and wide range of surface temperatures typically occurring during the normal operation of the vehicle, complicate the reliable operation of almost all types of detectors. This work presents a theoretical study assessing the effectiveness of different detection systems in a simulated fire scenario. Results from calculations and Computational Fluid Dynamics (CFD) simulations of a well defined fire in a standardised engine compartment are used to determine the gas temperature and smoke concentration across the compartment and how these are affected by different engine configurations and driving conditions. The effectiveness of different detection systems is studied by means of simulating a fire and analysing predictions measurements of temperatures and smoke concentrations resolved in time and space in the virtual compartment.
