摘    要：由于高温下煤粉燃烧的限制性环节是氧的扩散,根据氧传递学说和电子转移学说,提出了在煤粉中添加氧化助燃剂来改善煤粉燃烧的新方法,对三钢1000m³高炉喷煤助燃剂的使用情况进行了试验研究。试验结果表明:添加喷煤助燃剂后,煤粉燃烧率明显提高,为进一步提高煤比,降低焦比创造了条件。

Abstract: Oxygen diffusion is the restrictive step of pulverized coal combustion in high temperature,so a new method has been developed to improve combustion efficiency of pulverized coal in which combustion-supporting oxidant was added according to oxygen transfer theory and electron transfer theory.This paper summarized the experimental conditions on combustion-supporting agent on PCI can raise burning rate of powdered coal,which can create favourable conditions for raising coal ratio and reducing coke ratio.
