Modeling, optimization and control of a ceramic tunnel kiln …
Alex et al. (2023) simulated the firing process in roof tile and brick tunnel kilns, focusing on the effect of kiln wagon mass on energy consumption. Their results indicate that reducing the wagon mass could elevate the firing zone temperature, potentially resulting in lower fuel requirements to maintain the desired firing profile.

Application of coal-based direct reduction-magnetic separation process
After half a century of exploration, it developed into a direct reduced iron tunnel kiln called the Hoganas method. The Hoganas process is divided into two steps: first, the iron ore is directly reduced by carbon in the tunnel kiln to obtain the DRI block, then the DRI block is crushed and sorted, and finally, the direct reduced iron is obtained.
