Significance of burden distribution in the performance of a blast furnace

Abstract

The performance of a blast furnace is considerably influenced by burden distribution. The bed permeability and efficiency of gas utilization are improved by proper distribution of burden materials. The burden distribution is significantly affected by adopting different types of charging system. The charging sequence plays specific role in each type of charging system. The Paul Wurth bell less top charging system offers more flexibility in distribution of burden materials at any desired location. The furnace performance with regard to productivity, fuel rate and hot metal quality can be certainly improved by changing the burden distribution pattern.
