一、前言 1978年初,武钢高炉才正式喷吹煤粉。由于设备、工艺方面还存在不少问题,1980年全厂高炉喷煤量仅31.3kg/t。今后随着我国能源构成的变化,重油在高炉喷吹物中的比率将越来越低,煤粉将成为武钢高炉几乎唯一的风口喷吹燃料。因此,大力增加喷煤量,充分发挥其经济效果,对于增铁节焦具有十分重要的意义。增加喷煤量后改善喷吹效果的关键在于掌握喷煤量、风温、鼓风湿度等参数影响理论燃烧温度的规律,合理地进行热补偿(有人称为温度补偿),以控制适宜的理论燃烧温度。作为这项研究的尝试,作者首先导出自然鼓风条件下理论燃烧温度计算公式,然后
I. Introduction In early 1978, WISCO blast furnace pulverized coal injection. Due to equipment, technology there are still many problems in 1980 blast furnace coal injection volume of only 31.3kg / t. In the future, with the change of energy composition in our country, the ratio of heavy oil in the blast furnace will be getting lower and lower, and the pulverized coal will become the almost only tuyere fuel for blast furnace in WISCO. Therefore, to increase the amount of coal injected and give full play to its economic effect, it is of great significance to increase coke-feeding coke. Increase the amount of coal injection to improve the injection effect of the key lies in grasping the amount of coal injection, air temperature, air humidity and other parameters affect the theoretical combustion temperature of the law, reasonable thermal compensation (also known as temperature compensation) to control the appropriate theory Burning temperature. As an attempt of this study, the author first derived the theoretical combustion temperature calculation formula under natural blast conditions, and then
