【摘要】20L spherical explosion vessel is a important instrument for gas, flammable liquid steam and dust explosion parameters research. A spherical explosion vessel used for gas, flammable liquid steam and dust explosion experiment was designed by using dynamic coefficient method under the basis of existing pressure vessel standard. The key step was how to convert from explosion transient load to equivalent static load. The hydraulic experiment and the explosion limit experiment were made by using the spherical explosion vessel. The results showed that LEL of methane was 4. 5% , UEL of methane was 14.0% ; LEL of ethanol steam was 2. 5% , UEL of ethanol steam was 15. 0% ; LEL of 10|xm magnesium powder was 45g/m3. The experimental data had little difference with those in former documents, so, The results showed that the multi-functional spherical explosion vessel was rational and scientific
