SPONGE IRON output Temperature Construction period. Midrex 300 C 3-4 years. HYL 300 2-3 years. SLRN 400 1.5-2 years. REITEC Tunnel kiln 70 6 - 9 months. Due to low availability of Water in dry areas which the Iron Ore Mines are. located,water Consumption in REITEC Tunnel kiln DRI process is very low.Some of the cooling air remains in the tunnel kiln and the remainder is expelled by the cooling exhaust fan. This air can sometimes be used in other applications such as dryers, preheaters, boilers, etc. With this gas flow pattern, the kiln can operate with greater efficiency. Oxygen profile. Fig. 5 shows a typical tunnel kiln oxygen profile.
