Abstract
The performance of iron-ore pellet induration plants, including their energy consumption, is critically dependent on the relative flowrates and conditions of gas streams involved in the process. Equations and procedures for gas flow and pressure balance calculations within a dynamic mathematical model of the complete grate/kiln induration process are presented. Detailed simulation results, including pellet temperature profiles, enthalpy balances, and heat losses for a particular operating plant are discussed. Energy consumption per tonne of product changes appreciably with production rate, and there is a rate at which the specific fuel usage is minimized. Fuel oil consumption is increased if part of the oil is burned in the grate furnace rather than in the kiln.
