一、前言目前,我国烧结能耗比较高,全国重点钢铁企业为85公斤标煤/吨(1985年平均值),高于国外一般水平。焦粉(煤粉)是烧结生产中的主要燃料,占整个工序能耗的80—85％。在烧结过程中,固体碳的燃烧为形成液相和其它反应的进行提供了必要的热量和气氛条件。显然,改善焦粉在烧结过程中的燃烧特性,提高燃料利用率,是烧结生产中值得研 I. Introduction At present, the energy consumption of sintering in our country is relatively high. The key steel enterprises in the country are 85 kg of standard coal per ton (1985 average), which is higher than the general level of foreign countries. Coke powder (coal) is the main fuel in sintering production, accounting for 80-85% of the energy consumption of the entire process. During sintering, the combustion of solid carbon provides the necessary heat and atmosphere conditions for the formation of the liquid phase and for the progress of other reactions. Obviously, to improve the combustion characteristics of coke in the sintering process, improve fuel utilization, it is worth to study sintering production
