Contrast this with conventional lignite drying methods , which burn coal as part of the process to generate the high-temperature energy they need for drying, creating a significant CO2 footprint .

I am not too sure about the heating of such a large unit and getting the internal part of the kiln to 800C. I am curious as to how and what method of heating will be needed. It looks like a big unit. To me most kilns are made from firebricks of some sort you cannot directly heat a metal shell, it would have to be lined. How is going to work?
