焦炭预热干燥技术的应用

Research and Application of Coke Preheating Drying Technology for BF

针对外购焦炭质量不稳定、水分波动大、影响高炉炉况顺行等问题,通过增设热风炉烟气主引风机及焦仓排气管轴流风机,改造供配电系统,完善自动化控制系统等措施,实现了焦炭水分的持续稳定,为高炉的生产顺行与低硅冶炼创造了有利条件,同时提高了热风炉废气综合利用率,显著提升了TRT发电量。

The unstable and moisture fluctuations metallurgical coke quality of the blast furnace may affect the good situation of blast furnace and other issues. By installation of main fan for hot air stove flue gas and axial flow fan for coke bin exhaust pipe, transforming the power supply and distribution system, improving the automation control system and taking other measures, sustained stability of coke moisture can be achieved, which created the favorable conditions for the blast furnace production smoothly and low silicon smelting, and improved the comprehensive residual heat utilization rate for blast furnace, and also significantly improved the TRT generating capacity.
