Auto Ignition temperatures in Volumes up to 0,5 m³

Project No. FF-FP 0363

Status:

ongoing

Aims:

Aim of this project is to get a basis for judging whether an extrapolation of auto ignition temperatures, determined in small volumina, to larger volumes is possible with respect to safety considerations, to get, based on the experimental data determined during this research project, reliable information on the amount of auto ignition temperature reduction with increasing volume as well as on the enlargement of the ignition delay time with increasing volume and to offer estimation methods for both auto ignition temperature reduction and ignition delay time enlargement.

Activities/Methods:

  • Experimental determination of the ignition temperature of selected substances in vessels of 0,15 m³ and 0,5 m³. The determination method is as far as possible identical to the standardized procedure.
  • Experimental determination of the ignition temperature of homogenous vapour/air mixtures of the selected substances in vessels of 0,15 m³ and 0,5 m³ with a modified method.
  • Checking if the Beerbower-correlation is usable without a loss in safety.
