Abstract—In textbooks on the metallurgy of iron, the chapter regarding the processes in the blast-furnace hearth must be supplemented with information regarding the calculation of the total energy of the composite blast, which determine the size of the combustion zone ahead of the tuyeres; and the total mechanical energy of the hearth gas, which characterizes the penetration depth of the hearth gas with respect to the furnace axis and the temperature at the center of the hearth. Constant monitoring of these total-energy values is required in the blast furnace. Those readings must be compared with the values for the best operating periods.
