The effect of vacuum pressure on the flammability limits of natural gas (NG)

The purpose of this study is to determine the effect of vacuum pressure on the flammability limits Natural Gas in a closed vessel explosionsat various initial pressures within 0.98 and 0.96 bar and at ambient initial temperature. Times and pressure of the explosions were recorded. Experimental inves...
