摘要: 采用自然环境中氧化试验装置,研究了硫化铁的自然氧化进程,根据硫化铁在自然环境中氧化进程的特征,提出了其氧化过程可以分为表层自热期、潜伏期以及加速氧化期 3个阶段。热量积聚在硫化铁自燃进程中起着关键性的作用。此外,又研究了原油、水分以及硫单质等因素对热量积聚过程的影响。结果表明,原油对热量积聚具有双重影响;水分对于自燃具有抑制作用;硫磺对硫化铁自燃初期影响比较小,后期主要起到外部热源的作用。

关键词: 硫化铁 , 氧化 , 自燃 , 热量积聚 , 影响因素

Abstract: Oxidation process of iron sulfides was observed by installation of oxidation experiment.Oxidation process of iron sulfide can be divided into three stages :surface layer self -heating period,incubative period and accelerative oxidation period. Heat gathering was the key factors for iron sulfide self -ignite.Effects of oil,water content and sulfur on heat gathering were explored using oxidation experiment installation.The results show that oil has complicate effect on self - ignite of iron sulfide.Water content can prevent iron sulfide from oxidizing.Sulfur has a little effect on initial stages of self -ignite,while in the final stage it can be as external heat source.

Key words: Iron sulfide , Oxidation , Self-ignite \ Heat gathering , Effect factors
