国内外关于混合气体可燃性及爆炸极限的标准化研究

Standardization Study of Gas Mixture Flammability and Explosion Limit at Home and Abroad

阐述了爆炸极限对国内外可燃气体分类的影响及类别对可燃气体的意义,分析了操作温度与爆炸极限的关系及修正方法,总结了不同类型的混合气体可燃性的判别及爆炸极限计算的标准化方法,提出了国内标准中存在的盲区及修订盲区问题的建议,为石化行业的设计及生产提供更精确、更安全的参考数据。

The paper states the impacts of explosion limit on gas mixtures classification and the significance of classification to gas mixtures; and analyzes the relations of operating temperature and explosion limit and the correction method; and summarizes the distinguishment of flammability and standard calculating methods of explosion limits of different composition gas mixtures. Meanwhile,both the blind zones existing in domestic standards and the revision suggestions are provided with more secure and accurate reference data for the design and production of petrochemical industry.
