Abstract

The probability of reactions in the coke-battery lining on the oven side is assessed. The temperature ranges corresponding to such reactions are determined. The reaction products that are thermodynamically possible are iron oxides (FeO, Fe₃O₄), carbon monoxide and dioxide (CO, CO₂), elemental sodium Na, and carbonates of calcium, sodium, and potassium (CaCO₃, Na₂CO₃, K₂CO₃). The carbon monoxide and dioxide formed may be involved in subsequent reactions or may form part of the coke-oven gas. The reaction kinetics, which depends on the porosity of the lining, the temperature conditions, the properties of the batch, and other factors, necessitates the minimization of direct contact between the lining, the batch, and the coking products. This is possible by applying special ceramic coatings to the bricks. On account of large temperature fluctuations, the harmful reactions will be particularly intense in the lining at the extreme heating channels and at charging and gas vents, and so preventive measures are particularly important in those regions.

焦炉衬里的化学效应。1. 与煤费的反应

摘要

评估炉侧焦炭电池内衬的反应概率。确定对应于此类反应的温度范围。热力学上可能的反应产物是氧化铁 (FeO, Fe ₃ O ₄ )、一氧化碳和二氧化碳 (CO, CO ₂ )、元素钠 Na 以及钙、钠和钾的碳酸盐 (CaCO ₃ , Na ₂ CO ₃ , K ₂ CO ₃）。形成的一氧化碳和二氧化碳可能参与随后的反应或可能形成焦炉气的一部分。反应动力学取决于内衬的孔隙率、温度条件、批料的性质和其他因素，因此需要尽量减少内衬、批料和焦化产品之间的直接接触。这可以通过在砖上涂上特殊的陶瓷涂层来实现。由于温度波动大，在极端加热通道和充电和排气口的衬里中有害反应会特别强烈，因此在这些地区采取预防措施尤为重要。
