Description
Coke oven gas (COG), as a kind of high heat value source, was projected to be injected into free board of the COREX melter gasifier. In this paper, a static model had been created based on mass and heat balances. The model was capable of calculating the temperature of free board, the quantity of COG injected and top gas. The results showed that the COG injection into free board can adjust its temperature efficiently. The quantity of COG burned ranged 3 Nm3/t to 20 Nm3/t when temperature is lower than 1323 K and the quantity of COG decomposed ranged 3 Nm3/t to 65 Nm3/t COG when temperature is higher than 1323 K. A maximum of 117.20 Nm3/t COG could be injected through nozzles to provide enough top gas for shaft furnace. Therefore, the maximum of the total COG quantity injected is about 132 Nm3/t; the minimum is 20 Nm3/t.
