Static Heat Energy Balance Mathematical Model for an Iron Blast Furnace

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.
