Spontaneous ignition of biofuels - a literature survey of theoretical and experimental methods
Blomqvist Per, Persson Bror
Swedish National Testing and Research Institute (SP)
Methods for assessing the risk of spontaneous ignition are reviewed. The most widely used engineering method today, the Frank-Kamenetskii method, is reviewed in detail. Further a new improved experimental method, the so-called crossing-point method, is reviewed. This new method considerably speeds up the testing procedure. The Frank-Kamenetskii theory is best suited for application on materials that do not have excessive moisture content and where the reactions can be sufficiently well described by a single order reaction of the Arrhenius type.
