Thermal regulation of the hearth by means of a blast-furnace model

A mathematical model of the lower heat-transfer zone is developed on the basis of heat-transfer theory and operational data for blast furnaces in Europe, the Commonwealth of Independent States, China, and the United States. This model may be used to determine the theoretical combustion temperature o...

Description
Summary:A mathematical model of the lower heat-transfer zone is developed on the basis of heat-transfer theory and operational data for blast furnaces in Europe, the Commonwealth of Independent States, China, and the United States. This model may be used to determine the theoretical combustion temperature of coke. On that basis, a relation is derived between the theoretical combustion temperature of coke, the yield of blast-furnace gases, and the degree of direct reduction of iron, when coal-dust fuel is employed.
