Total energy of the hearth gas in pulverized-coal injection

Abstract

Recommendations are made for calculation of the total energy of the hearth-gas flux in pulverized-coal injection. That permits monitoring of the mean total energy and the energy at each tuyere in the blast furnace. On that basis, the penetration depth of the hearth-gas flux toward the center of the furnace may be regulated for each tuyere, and hence the gas-dynamic and reducing conditions in the blast furnace may be improved.
