KILN TEMPERATURE PROFILE. In a rotary kiln system producing cement clinker, gas flows are counter-current to material flows. Gases enter the kiln as secondary air at about 600°C – 1100°C and rise abruptly to over 1750°C as heat from fuel combustion, and the exothermic heat of clinker formation are released.
