In der Folge konnte in den letzten fünf Jahren eine deutlich gestiegene Zahl von Bränden in Holzlagern und -halden festgestellt werden. Viele dieser Brände sind durch Selbstentzündung des Materials verursacht worden. Sind die Ursachen der Selbstentzündung bekannt, kann die Brandentstehung durch geeignete Maßnahmen vermieden werden. Die Fachgruppe II.2 „Reaktionsfähige Stoffe und Stoffsysteme“ der Bundesanstalt für Materialforschung und -prüfung hat in diesem Leitfaden das Thema aufgegriffen und die derzeit vorliegenden Erkenntnisse zusammenfassend dargestellt. Ziel des Leitfadens ist es, die Grundlagen der Selbstentzündung von Biomasse am Beispiel von Holz in übersichtlicher Form darzustellen und daraus praktische Hinweise zur Vermeidung der Selbstentzündung von Holzhalden abzuleiten, um so einen Weg für einen sicheren und nachhaltigen Umgang mit diesem Rohstoff zu ebnen. Dem Leitfaden liegen Ergebnisse des Forschungsvorhabens „Brandvermeidung bei der Lagerung von biogenen Brennstoffen“ zugrunde. Das Projekt wurde innerhalb der Fördermaßnahme „klimazwei – Forschung für den Klimaschutz und Schutz vor Klimawirkungen“ des Bundesministeriums für Bildung und Forschung finanziell gefördert (Förderkennzeichen 01LS05079). Für diese Förderung möchten die Autoren sich bedanken.

T1 - Study of the spontaneous ignition of stoichiometric tetrafluoroethylene-air mixtures at elevated pressures N2 - The Ignition Temperature (IT) of stoichiometric tetrafluoroethylene–air mixtures on hot walls was determined in a 3-dm³-reactor. Tests at elevated pressure conditions were performed, namely at 5, 15 and 25 bar(a), showing a decrease of the IT with the initial pressure. Furthermore, the measured ignition temperatures of stoichiometric tetrafluoroethylene–air mixtures were lower than the ignition temperatures required for the decomposition pure tetrafluoroethylene (Minimum Ignition Temperature of Decomposition, MITD) reported in previous works. Equations from the Semenov thermal explosion theory on spontaneous ignition were used to identify approximate combustion kinetics of tetrafluoroethylene from the experimental results. The determined kinetics was used for the prediction of the IT of stoichiometric tetrafluoroethylene-air by simplified calculation methods. A very good agreement with the experimental results was observed.

T1 - The explosive decomposition of tetrafluoroethylene: large scale tests and simulations N2 - There is a lack of data on the self-ignition behaviour of tetrafluoroethylene (TFE) in industrial sized equipment. In order to assess the tendency of TFE for decomposition in large scale vessels, , a facility was designed and constructed. Tests were carried out in a cylindrical reactor with a volume of 100 L with initial pressures of 5 and 10 bar(a). The effect of the reacto r adjustment (vertical or horizontal) was taken into account. The current work describes the test set up and summarizes the experimental results achieved. Furthermore, this paper reports on a numerical model for the prediction of the self -heating of TFE in closed vessels, which was previously developed for small scale reactors and has been here validated for larger dimensions with the experiments performed in the new facility.

The cases of a direct engulfment of the cylinder in the flames and of exposure to a distant fire were considered. Furthermore, the model was also applied to the prediction of the heat transfer during the cooling with water of heated acetylene cylinders, in order to assess the effectiveness of this procedure as a measure to prevent the burst of the cylinder. To provide data for the definition and validation of the model a total of 13 bonfire tests with 8.9-, 10- and 50-dm³-cylinders were performed, where pressure and temperature measurements in the samples were performed. During 5 experiments the fire was extinguished before the expected cylinder burst and a cooling with water was applied. In the paper a short description of the experimental set-up and of the test results is given. Finally, a comparison with the model predictions is provided, showing reasonable agreement.

A1 - Schröder, Volkmar T1 - On the minimum ignition temperature for the explosive decomposition of tetrafluoroethylene on hot walls: Experiments and calculations N2 - The Minimum Ignition Temperature of Decomposition (MITD) of tetrafluoroethylene in a partially heated pipe was analyzed for different initial pressures (5, 10 and 15 bara). The pipe used had an internal length of 1 m, an internal diameter of 30 mm with a volume of about 0.7 dm³ and was vertically oriented. Pressure at the pipe top and temperature at four different locations along the pipe axis were measured. Tetrafluoroethylene was found to decompose at lower temperatures for increasing initial pressures, in agreement with previous tests with reactors with fully heated walls. A complete passive quenching in the non-heated part of the pipe was observed only for an initial pressure of 5 bara, while for higher initial pressures, the decomposition propagated completely along the test pipe. Moreover, the test results on the MITD were compared with data from previous experiments in fully heated 0.2 and 3 dm³ cylindrical reactors and showed a decrease of the MITD with the heated volume through heated surface ratio of the vessel. Furthermore, the prediction of the MITD of tetrafluoroethylene by simplified calculation methods was attempted, showing a good agreement with the experimental results.

T1 - Self-ignition of tetrafluoroethylene induced by rapid valve opening in small diameter pipes N2 - This work investigates the ignition of tetrafluoroethylene induced by the adiabatic compression that can arise by activating a high speed valve separating two portions of a pipeline with a high pressure difference. In the tests performed the high pressure zone contained tetrafluoroethylene at pressures between 15 and 30 bar. For the low pressure zone, experiments with nitrogen, air and tetrafluoroethylene were carried out. The pressure range in the low pressure zone was comprised between 0.05 and 1 bar. The pipe diameters analyzed were 15 and 20 mm. For the analyzed geometries, special conditions were required in order to reach reproducible ignitions, namely air at temperatures of at least 105 °C had to be present in the compression pipe. Furthermore, a minimum length of the compression pipe had to be used. The current work describes the experimental setup employed for the tests and discusses the achieved results. Numerical simulations were performed in order to clarify unexpected findings.

Damit Acetylen in entsprechenden Mengen vor Ort zur Verfügung gestellt werden kann, wird es in Druckgasbehälter abgefüllt. Im Falle eines Brandes stehen Acetylenflaschen im Verdacht, jederzeit – auch nach Löschen des Feuers – aufgrund einer möglicherweise initiierten Zerfallsreaktion zu bersten. Um insbesondere Personenschäden zu vermeiden, evakuieren und sperren die Rettungskräfte einen Sicherheitsbereich mit einem Radius von mindestens 200 m um die verdächtige Flasche ab. Gleichzeitig wird umgehend mit der Kühlung der Flasche begonnen. Wie lange muss aber eine Acetylenflasche gekühlt werden, bis sie sicher abtransportiert werden kann, und wie lange muss der Sicherheitsbereich mit dem großen Radius aufrecht erhalten werden? Diesen Fragen ist die BAM in den vergangenen Jahren im Rahmen verschiedener Untersuchungen und Projekte nachgegangen.
