On explosion limits of H2/CO/O2 mixtures

Models to Estimate the Lower Explosion Limits of Dusts, Gases and Hybrid Mixtures

The present paper reports on the experimental and theoretical investigations on the lower explosion limits of single dusts, gases as well of two phase mixtures such as gas/dust, vapor/dust, spray/vapor and vapor/gas. The materials used were corn starch, lycopodium, toner and high density polyethylene as dusts, methane and hydrogen as combustible (perfect) gases and acetone and isopropanol as sp...

Explosion properties of aerosol/air mixtures

Combustion hazards associated with liquid fuels are often categorized in terms of the fuel’s flashpoint. However, in hazard scenarios where high-flashpoint fuel is released under pressure, jet breakup and aerosol formation will result. In these cases, this simplistic method of combustion hazard classification may be not sufficient and then alternative approaches are required. As for gases and d...

Explosion pressures of hydrocarbon-air mixtures in closed vessels.

An experimental study on pressure evolution during closed vessel explosions of several gaseous fuel-air mixtures was performed, at various initial pressures within 0.3-1.2 bar and ambient initial temperature. Explosion pressures and explosion times are reported for methane-, n-pentane-, n-hexane-, propene-, butene-, butadiene-, cyclohexane- and benzene-air mixtures. The explosion pressures meas...

Explosion effects on buildings

Nowadays there are many software tools available which, in case of a gas release, allow to calculate the dispersion of the gases (and hence predict the size and shape of the cloud) and to calculate the overpressures as a function of distance if this gas cloud should explode. The next step is then to predict what the consequences of these overpressures will be: to what extent will buildings (and...
