ABSTRACT: Most explosion characteristics published so far are valid for specific and limited conditions. No explosion characteristic exists for COG which cover all conditions occurring in “real life” and resulting conditions. This requires more information and systematic investigation of the explosion parameters of COG in air under various conditions. Two experimental models were used with the aim at simulating the gas explosion in the middle scale explosion vessels, and the associated effects of the temperature for different gas/air concentrations. The explosion pressures and the rate of pressure rise were determined as a function of the fuel/air ratio at different initial temperatures and pressures. Based on these experimental data, the maximum explosion pressure and the maximum rate of pressure rise were determined as a function of pressure and temperatures. The deflagration index and also the laminar burning velocity were calculated from these data too and compared with the experimental results measured in 20-L and 1000-L spherical vessels.
