从维持适宜理论燃烧温度和使富氧效益最大化2个方面对高炉适宜富氧量进行了探讨,提出了煤焦临界置换比、增益临界富氧率、临界富氧气体价格等有实际意义的概念,并给出了相应的计算公式。
The proper oxygen enrichment of blast furnace was discussed from two aspects of maintaining appropriate theoretical combustion temperature and maximizing oxygen enrichment efficiency. It was proposed that the critical replacement ratio of coal, the critical oxygen enrichment rate, the price of critical oxygen-rich gas, etc. have practical significance Concept, and gives the corresponding formula.
