Why does ferrous sulfide self-ignite, and how can it be prevented? Due to its unstable chemical properties, ferrous sulfide undergoes an oxidation reaction when exposed to oxygen (air). When the heat generated by this reaction reaches its autoignition point, ferrous sulfide will ignite on its own. The preventive method is to prevent contact between oxygen (air) and ferrous sulfide; if spontaneous combustion of ferrous sulfide is detected, measures such as flushing with water and isolating oxygen (air) should be taken immediately to ensure the safety of the equipment.

Ferrous sulfide is not a pure substance; it mixes with coke powder, oil residues, and other substances to form scale, and its structure is generally loose. When ferrous sulfide oxidizes in humid air, ferrous ions are oxidized to ferric ions, and sulfur with a valence of -2 is oxidized to sulfur with a valence of +4, releasing a large amount of heat. Due to the local temperature increase, the oxidation of the surrounding ferrous sulfide is accelerated, triggering a chain reaction. If carbon and heavy oil are present in the fouling, they will burn rapidly under the action of ferrous sulfide, releasing more heat. This spontaneous combustion phenomenon can easily lead to fire and explosion accidents. Preventive measures: 1. Limit the formation of ferrous sulfide. 2. Clean the corroded parts of the equipment promptly. 3 Try to avoid the mixing of C and organic substances.
Iron sulfide can release heat through oxidation reactions, and this chemical property is the main cause of \"spontaneous combustion\". It reacts more easily with oxygen to release heat in humid conditions. If ferrous sulfide contains combustible impurities, the likelihood of combustion increases. Preventing the spontaneous combustion of ferrous sulfide mainly involves controlling oxygen concentration and keeping it dry. For chemical analysis reagents, the preventive measure is to store them in dry and sealed conditions, right?
