Abstract
In this study a static heat energy balance analysis has been carried out for an iron blast furnace. The objective of this work is to provide a mathematical calculation model of the heat distributions for the various components of the blast furnace. The model presented, is also indicative to the amount of excess fuel being charged. To prepare a proper heat balance, the first step is to attain a proper mass balance calculation. To do so, each input and output materials has been analysed, and the respective elemental compositions have been calculated. All major components and reactions of a blast furnace have been included in the study. Each calculation has been done with sufficient details, to allow estimation of heat requirements, according to the working conditions of a blast furnace.
Highlights
Heat energy analysis is a very major study for the proper operation of a blast furnace

The model takes into consideration all the factors which play a significant role, in the heat requirements of a blast furnace
Summary
Heat energy analysis is a very major study for the proper operation of a blast furnace. A material balance is an account of input and output of mass, governed by the law of conservation of mass. A proper material balance will provide accurate quantitative values, thereby simplifying calculations in each step of the heat balance. A detailed study of each input and output components of the blast furnace has to be carried out, which includes: 1. A heat balance analysis for a continuous production blast furnace was presented by [1]. The authors gave a simplified model to calculate heat distributions for various components of the furnace. Taking [1] as reference, the following study has been conducted to calculate exact heat distributions of each input and output component of the furnace, in detail. Composition analysis of all materials has been carried out using XRF analysis, and BF gas analysis has been carried out using Orsat absorption method
