چکیده

În prezenta lucrare a fost realizat un studiu asupra evoluţiei presiunii în timpul exploziei sub formă de deflagraţie produse în amestecuri propan-aer aflate într-o celulă cilindrică (Φ = 10 cm; h = 15 cm) cu aprindere centrală, la diferite concentraţii iniţiale de propan (între 2.60 şi 5.70%, in vol.), la diferite presiuni iniţiale (între 0.3 şi 1.3 bar) şi la temperatura iniţială ambiantă. Sunt discutate influenţa presiunii şi concentraţiei iniţiale asupra presiunilor de explozie, a timpilor necesari atingerii presiunilor maxime de explozie şi a vitezelor maxime de creştere a presiunii. Presiunile maxime de explozie măsurate au fost comparate cu valorile din literatură şi cu presiunile adiabatice de explozie.

Explosion Pressures of Confined Deflagrations Propagating in Stoichiometric Gaseous Mixtures of Lower Alkanes with Air

An experimental study on maximum explosion pressure in closed vessel deflagration of stoichiometric gaseous mixtures, for various initial pressures within 0.3 – 1.2 bar and ambient initial temperature is reported. Explosion pressures and explosion times of stoichiometric methane-, ethaneand propane-air mixtures were measured in a spherical vessel and in two cylindrical vessels with different di...

Explosion Severity: Propane versus Natural Gas

Natural gas, composed mainly of methane, is in some ways similar to propane gas. Both fuels have similar energy densities per unit mass, and similar laminar premixed flame burning velocities. However, propane explosions have been shown to produce higher overpressures in unconfined explosion tests when compared to methane. In vapor cloud explosion modeling, methane is considered to be a “low” re...

Initial Pressure and Mixture Composition Influence on LPG-air Confined Explosions

Values of some characteristic parameters of confined explosions for LPG (Liquefied Petroleum Gas)-air quiescent mixtures are examined in correlation with the initial pressure of fuel-air mixture and fuel/air ratio. The explosion pressures, the explosion times and the maximum rates of pressure rise were obtained from experiments made at ambient initial temperature in two closed vessels with cent...

The upper explosion limit of lower alkanes and alkenes in air at elevated pressures and temperatures.

The upper explosion limit (UEL) of ethane-air, propane-air, n-butane-air, ethylene-air and propylene-air mixtures is determined experimentally at initial pressures up to 30 bar and temperatures up to 250 degrees C. The experiments are performed in a closed spherical vessel with an internal diameter of 200 mm. The mixtures are ignited by fusing a coiled tungsten wire, placed at the centre of the...

The Convective Dispersion of Flammable Mixtures within Open Cylindrical Enclosures following the Release of a Fixed Mass of a Gaseous Fuel

There are many practical situations where a finite mass of a buoyant gas may become suddenly exposed to atmospheric air at a negligible pressure difference within vertical chambers or vessels that are either fully or partially open. The consideration of such situations when a fuel or toxic gas is released is of immense practical importance especially in relation to developing measures for prote...
