摘要
参照国标GB/12474-90的有关规定,设计了一套测试可燃气体爆炸极限的实验装置。系统地测量了三元混合物R290+R152a+R134的爆炸极限,积累了爆炸极限数据,绘制了爆炸极限曲线。混合物的临界爆炸比(CFR),随着R290/R152a体积比的增大而增大。
An experimental apparatus was built to measure the flammability limits of combustible gases, as per the Chinese National Standard GB/T 12474-90. Extensive measurements were made on the flammability limits of ternary mixtures of propane/l, 1-difluoroethane/1,1,2,2-tetrafluoroethane. Experimental da- ta and flammability limit curves were obtained for the mixtures with variation of the concentration ratio of the inert to the fuel. The critical flammability ratio（CFR） of the mixture increases as the molar ratio of R290 to R152a increasing in the blend.
