Abstract
A process for measuring, optimizing and controlling the gas permeability of a sinter mixture on a travelling grate by adjusting the flow of air and/or fuel to the furnace to maintain a zero pressure differential between the inside and the outside thereof such that all the gas generated permeates the sinter mixture, and determining the gas permeability as a function of said flows. These steps are repeated for various values of selected process parameters having a significant influence on gas permeability, one at a time, in order to determine the value of each parameter which produces optimum gas flow.
