高炉富氧喷煤是实现高炉稳产、高产、优质、低耗的必要手段,是高炉炼铁技术进步的重要标志。高炉的富氧和喷煤是互为条件,互为依存的。喷煤量不断增加,就需要有足够的氧气来促进煤粉的燃烧,以提高煤焦置换比和保证高炉顺行。 Blast furnace oxygen-rich coal injection is the necessary means to achieve stable production, high yield, high quality and low consumption of blast furnace, and is an important symbol of the technological progress of blast furnace ironmaking. Oxygen blast furnace and coal injection are mutually dependent and interdependent. Increasing the amount of coal injection, you need to have enough oxygen to promote the combustion of pulverized coal in order to improve the coal-to-coal conversion ratio and to ensure smooth blast furnace.
