On the consideration about the optimum number of tuyeres of blast furnace, the race way depth in comparison with the hearth diameter is noted.
As the measure of active race way depth in general, “the active race way dimension rate” (η) is adapted to the analysis of relations between practical data.
In the cases of good operation results of blast furnaces, the values are in the range from 0.45 to 0.50. Therefore, the equations for determining the optimum number of tuyeres are derived by taking η=0.47.
By taking the generalized combined blast condition into consideration, the constant term in LEONIDOV'S formula is analyzed to get a more optimum answer. Also, the validity of this equation is proved by the data from the blast furnace in operation.
