Abstract The temperature distribution of COREX melter gasifier was studied by using a two-dimensional 1/30 scale thermal dynamic model. A set of operating conditions, such as radial distribution of direct reduction iron (DRI) to lump coal and coke volume ratio, coke charging location, coke charging amount and coke size, were taken into account. The results show that the temperature near the wall region decreases with the decrease of the radial distribution of DRI to lump coal and coke volume ratio. The temperature with central coke charging is higher than that without central coke column. Furthermore, the temperature significantly increases with the increase of central coke charging amount. With the increase of intermediate coke charging amount, the temperature near the wall region decreases while the temperature in the intermediate region increases. The temperature increases with the increase of coke size whether charging central coke or intermediate coke.
