    Mathematical model for a straight grate iron ore pellet

    Dec 01, 2008 Hamidi and Payab have presented a mathematical model for pilot-scale iron ore induration furnace and have determined energy savings by coke addition to the pellet and oxygen injection to the furnace. Pomerleau et al. 16 have used a mathematical model for optimization of the operating conditions in a straight grate furnace.

    Mathematical model for a straight grate iron ore pellet

    A mathematical model is developed for induration of the iron-ore pellets in an industrial-scale plant based on the laws of mass, heat and momentum transfer. Physicochemical processes occurring during the induration of pellets such as drying of moisture, calcination of limestone and coke-magnetite reaction are considered to evaluate the gradient ...

    Optimizing the operation of straightgrate ironore pellet

    Mathematical models of straight-grate pellet induration processes have been developed and carefully validated by a number of workers over the past two decades. However, the subsequent exploitation of these models in process optimization is less clear, but obviously requires a sound understanding of how the key factors control the operation. In this article, we show how a thermokinetic model of ...

    A dynamic mathematical model of the complete gratekiln

    Induration drying and hardening of iron ore pellets is an energy-intensive feed preparation step for both the blast furnace and direct reduction routes to iron. It is commonly carried out by a gratekiln process. A mathematical model of the process is described, in which mechanistic models of the grate furnace, kiln, and cooler are linked to enable simulation of the entire process.
