摘要: 通过气体动力学和热力学分析,导出了球形及圆筒形容器内发生可燃气爆炸时,容器上泄压装置的最适泄放面积计算式,并以乙烯与空气的混合气为爆炸介质、爆破片为泄压装置,在圆筒形容器内进行了大量实验验证.结果表明,理论与实验结果相吻合.

Abstract: By analysing the discharge characteristics of flammable gas explosion, an expression was derived for the proper venting area for spherical and cylindrical vessels withstanding internal flammable gas explosion. A series of experiments were carried out with C2H4/air mixtures and rupture discs in four cylindrical vessels. The experimental results show a good agreement with the theoretical results.
