Blast-furnace dynamics and the static pressure losses

Abstract

In the interaction of the forces responsible for the motion of batch and gases, account must be taken not only of the gravitational force on the batch column but also of the gravitational force on the gases. Accordingly, the difference in the work of the gravitational forces on fluxes corresponding to the lower and upper pressure losses must be determined. The work increases with increase in gas pressure in the furnace. Consequently, the pressure losses increase without preventing the intensification of the blast-furnace process.
