我国高炉喷煤技术的发展

论述了我国高炉喷吹煤粉技术的发展过程，分析了提高高炉喷煤比的措施，通过提高焦炭质量、改善鼓风质量、采用氧煤喷吹、混合喷吹等技术和工艺措施可有效提高喷煤比。同时指出，研究回旋区条件下煤粉的燃烧过程，开发高效喷煤助燃剂，最大限度地提高煤粉在风口区域的燃烧率和喷煤置换比，是当前喷煤技术攻关的课题。

Technology Development of Pulverized Coal Injection of China's Blast Furnace

This paper introduced the technology development of pulverized coal injection of China's blast furnace and analyzed the measures of increasing PCI rate.By means of increasing quality of coke, improving quality of air blast, using oxygen-coal injection and mix injection technology etc can effectually increase the PCI rate.At the same time, it pointed out that studying combustion course of coal power in the condition of raceway zone and developing high efficiency PCI combustion-supporting agent for increasing...
