Kiln Connection: Tunnel Kiln Energy Considerations
To simplify matters, we will work backwards from a known tunnel kiln and develop the energy evaluation starting with the existing fuel consumption. A kiln I am familiar with is 300 ft long, with a setting width of 10 ft, firing sanitaryware on a 10-hour cycle. The gross fuel consumption of this kiln is 2000 Btu/pound of green ware.

Sponge Iron
DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines.
