Radiant heat from propane jet fires
Sonic propane jet fire experiments were carried out in absence of wind, with visible flame length ranging between 2.2 and 8.1 m. The thermal radiation intensity increased with the mass flow rate and the flame length. The net heat released was also computed and a correlation for the flame length as a function of Q is proposed. The surface emissive power and the fraction of heat irradiated were e...
متن کاملExperimental methodology for characterizing flame emissivity of small scale forest fires using infrared thermography techniques
An experimental methodology based on thermography techniques has been developed and implemented with the aim of finding emissivity values of forest fuel flames. In this paper, previous works by different authors are discussed and theoretical fundamentals of heat transfer by radiation and of infrared thermography on which experimental method relies are briefly described. Then, designed methodolo...
متن کاملJet Fires: a “Minor” Fire Hazard?
Jet fires have received only a rather reduced attention as compared to other types of fires; this is probably due to the fact that they are usually much smaller that fireballs, pool fires or tank fires. However, jet fires often occur in areas where there is other equipment and the probability of flames impinging on a pipe or a vessel can be high. Furthermore, due to the turbulence of the phenom...
متن کاملThe Behaviour Of Vertical Jet Fires Under Sonic And Subsonic Regimes
Accidental release scenarios such as flammable gas leaks or ruptures of pipes and pressurised process-equipment normally originate high velocity jets which, if ignited, give rise to jet fires. Although the direct effects of jet fires are considered to be relatively smaller than that associated to other types of fires, they are characterized by high heat fluxes and, especially if there is flame ...
متن کاملThermal and Geometrical Features of Jet Fires
In many severe accidents involving explosions or large fires, jet fires have been the first step of a domino effect sequence: a recent historical analysis has shown that among the accidents registered in the data bases, in approximately 50% of the cases in which it was a jet fire it caused another event with severe effects. However, the knowledge of jet fires essential features –behaviour, effe...
