Approach determining maximum rate of pressure rise for dust explosion

Journal of Loss Prevention in the Process Industries, 2014
Abstract The risk assessment requires the knowledge of dust explosion hazard data. Maximum rate of pressure rise is an important parameter of explosion severity characteristics. Its accuracy depends on the experimental conditions and the approach determining maximum rate of pressure rise.

Maximum explosive pressure and temperature of vapor-air mixtures

Coke and Chemistry, 2011
For mixtures of air with highly inflammable vapor, the maximum explosive pressure corresponds to superstoichiometric fuel concentrations. The maximum explosive pressure is similar for different classes of compounds and considerably exceeds the handbook values. This must be taken into account in predicting the consequences of explosions.

Temperature and pressure influence on maximum rates of pressure rise during explosions of propane–air mixtures in a spherical vessel

Journal of Hazardous Materials, 2011
The maximum rates of pressure rise during closed vessel explosions of propane-air mixtures are reported, for systems with various initial concentrations, pressures and temperatures ([C(3)H(8)]=2.50-6.20 vol.%, p(0)=0.3-1.3 bar; T(0)=298-423 K). Experiments were performed in a spherical vessel (Φ=10 cm) with central ignition. The deflagration (severity)

The Effect of Unequal Temperature Distribution on the Maximum Pressure Developed in Explosions in a Closed Vessel

The Journal of Chemical Physics, 1934
When a combustible gas mixture is exploded at the center of a spherical vessel, a temperature gradient is established at the moment of maximum pressure which rises from the wall to the center. The maximum pressure recorded is lower than would have been found had the temperature been equalized without heat loss.

Maximum explosion pressure for rich methane-oxygen mixtures

Combustion, Explosion and Shock Waves, 1993
The maximum pressures achieved during the self-ignition of a 2CH4+O2 mixture in a closed heated vessel at initial pressures of 11, 16, 21, 26, and 31 atm are measured. Experimental data are compared with thermodynamic calculations based on the principle of conservation of gas density during the combustion.

Maximum explosion pressure in flameproof enclosures: The effects of the vessel and the ambient temperature

Journal of Hazardous Materials, 1984
Abstract Explosion pressures measured in the Westerberg apparatus for determining the design requirements of flameproof enclosures in various flammable atmospheres (as generally used in the U.S.A.) are not the same as pressures measured in a 4-1, spherical explosion vessel generally used in the U.K.
