摘要

摘要考虑了高炉滚道周围的各种物理化学现象,建立了一个新的滚道热物质平衡模型。该模型是独特的,因为它考虑了基于热力学的反应,并确定了重要参数,如滚道绝热火焰温度(RAFT)、波什气体特性、滚道焦炭率等。重要的是,该模型还预测了已知RAFT和熔炉渗透性情况下的吹制参数。本文只考虑了不同注入剂H2、CO、CH4、CO2和焦炉气(COG)的影响,重点研究了滚道状态。首先,本文描述了基于热力学、热平衡和材料平衡的建模方法。本文的第一部分量化了在保持吹制参数不变的情况下,注射剂对滚道的影响,而第二部分则介绍了在保持RAFT和炉内渗透性不变的条件下,滚道性能以及吹制参数的变化。

A theoretical approach to evaluate the effect of hydrocarbon and CO2 injection on blast furnace raceway: step towards reduction of CO2 emission
ABSTRACT A novel raceway heat and material balance model is developed considering all physico-chemical phenomena surrounding the raceway of the blast furnace (BF). This model is unique, as it considers reactions based on thermodynamics and determines important parameters such as raceway adiabatic flame temperature (RAFT), bosh gas properties, raceway coke rate etc. Importantly, the model also predicts blowing parameters in case of known RAFT and permeability of the furnace. This paper focuses on the raceway regime only considering the effect of different injectants, H2, CO, CH4, CO2 and coke oven gas (COG). Firstly, the paper describes the modelling approach, based on thermodynamic, heat and material balances. The first part of the paper quantifies the effect of injectants on the raceway keeping the blowing parameters constant, whereas second part presents the changes of raceway properties as well as blowing parameters keeping RAFT and permeability of the furnace constant.
