| Abstract: | The explosion process of flammable gas was researched in this paper, according to the second law of thermodynamics and principle of isolated system entropy increase.Calculation formula of one-component gas explosion limit was set up and checked with the practical example. Analysis and appraise about the generality and precision of the result about the calculation provided scientific basis for computation of explosive limit about flammable gas. |
