Abstract

The distribution of natural gas into the blast channel of a blast-furnace air tuyere with a heat-insulating insert enhances the mixing of gas with the blast air and improves combustion efficiency. Numerical simulations were conducted using Ansys to analyze gas dynamics, heat transfer, and natural gas combustion during injection through a collector cavity and a set of holes in the tuyere flange. The effects of the diameter and number of flange holes on tuyere performance were investigated. The thermal and gas-dynamic performance of the tuyere and the thermal stresses in the insert were found to depend on the ratio of cross-sectional areas at the inlet and outlet of the collector.

法兰设计对带隔热衬板的高炉风口性能的影响

天然气进入带有隔热嵌套的高炉风口的风道，加强了天然气与鼓风的混合，提高了燃烧效率。利用Ansys进行了数值模拟，分析了通过集热器腔和风口法兰上的一组孔喷射过程中的气体动力学、传热和天然气燃烧情况。研究了法兰孔直径和孔数对风口性能的影响。研究发现，风口的热动力和气体动力性能以及插片内的热应力取决于集热器入口和出口的横截面积比。
