| Abstract: | It is a safety guarantee for exploration,development and utilization of natural gas containing high carbon dioxide component to grasp the explosion characteristics of methane and carbon dioxide gas mixtures.Meanwhile,it is valuable guidance for the industrial processes involving methane and carbon dioxide such as coal gasification,inertization,explosion suppression and explosion venting,to master related explosion characteristics.In order to promote progress of relevant subject,experimental and theoretical investigation on explosion characteristics of methane and carbon dioxide gas mixture is reviewed systematically in this paper,including the experiments related to flammability region,explosion pressure and inertization and theoretical prediction of flammability limits.Progress and problems that need to be solved in every field are analyzed.Finally,the future highlights in the following three aspects are expected: firstly,how to improve the integrality,comparability and applicability of experimental data;secondly,the methods and indexes of reliability assessment for theoretical prediction;furthermore,how to extend applicability of theoretical prediction from at normal temperature and pressure conditions to more complex situations. |
