More Information
Summary:A method and apparatus for measuring the percentage reduction of iron ore in a reduction reactor of a multiple reactor gaseous reduction system. In accordance with a preferred embodiment, the flow and composition of the reducing gas fed to the reduction reactor and the flow and composition of the reactor effluent gas after cooling are measured and the measurements are fed to a computer along with data on the initial weight of the charge to the reactor, the moisture content of the charge and the initial reducible oxygen in the charge. The computer is programmed to compute the rate of oxygen removal from the charge, integrate the rate of removal with respect to time and compare the integral with the initial oxygen content of the charge to evaluate percentage reduction thereof.
