可燃制冷工质的爆炸极限研究综述

Review of explosion limit study on combustible refrigerants

从爆炸极限的定义、爆炸容器、点火方式、流动状态、选择性扩散等方面,阐述了实验研究的进展;从可燃物的爆炸极限预测方法出发,概述了估算研究的成果。到目前为止,实验测定的方法还没有统一的标准,理论估算的误差也比较大。指出了颇有争议性的问题和亟待研究的空白,并对进一步的研究工作提出了若干建议。

The improvement on experiment study was illustrated on the basis of explosion limit definition, explosion vessel, ignition method, hydrodynamic condition and selective diffusion. The previous results were summarized referring to prediction methods on explosion limit of flammable mixtures. So far, there is still no uniform standard in the experimental methods and there are also some great differences between the theoretical evaluation result and experimental measurement data. Moreover, several controversial problems and investigation vacancy were pointed out and some suggestions were proposed for further study on explo- sion limit after careful and systematic review.
