Energy Efficiency In Tunnel Kiln Dri Process

FACT SHEET Energy use in the steel industry

of metallic iron such as direct-reduced iron DRI or hot metal can also be used.Additives are used to adjust the steel to the desired chemical composition. Electricalenergy can be supplemented with oxygen injected into the EAF. Downstream process stages


The most advanced kiln technology in brickmaking is the tunnel kiln. In the tunnel kilnlike the annular kiln the firing ofbricks is a continuous process but unlike theannular kiln the firing zone remains stationary while the bricks move through the kiln.
