The behavior of acetylene cylinders involved in fire: An experimental and numerical analysis

  • Fire exposure tests of acetylene cylinders were performed. The purpose of the experiments was to gather information on the behavior in fire of such vessels, depending on the initial charge of acetylene. In fact "empty" acetylene cylinders still contain the solvent in which acetylene is dissolved plus the amount of acetylene to saturation at atmospheric pressure and ambient temperature and may still constitute a threat to safety. In the fire exposure tests performed the hazardousness of these vessels was demonstrated, since it was observed that not only fully charged acetylene cylinders but also cylinders with saturated solvent can explode, provided the heat transfer to the vessel is sufficient. The times to explosion were shorter for fully charged cylinders, due to the higher initial pressure and to the faster pressure increase. The effects of the explosions are comparable for both fully charged cylinders and for cylinders with saturated solvent, except for the smaller fireball whichFire exposure tests of acetylene cylinders were performed.

The times to explosion were shorter for fully charged cylinders, due to the higher initial pressure and to the faster pressure increase. The effects of the explosions are comparable for both fully charged cylinders and for cylinders with saturated solvent, except for the smaller fireball which is produced in the second case, due to the smaller amount of fuel available. In both cases the cylinder walls or at least fragments can fly further than 100 m away from the burst location. Results of the experiments are presented in the paper. During the tests, temperature measurements at the cylinder walls and in the cylinder interior were performed. Furthermore, the pressure in the cylinder was recorded. The collected data will serve for the validation of a numerical model for the simulation of the heating of acetylene cylinders involved in fire and of the afterward cooling with water, which has been developed. The constitutive model equations and the results of some simulations are presented in the paper.zeige mehrzeige weniger
