There are a number around, I have had "experience" with these two:

If you go for a romp on Google under “lime kiln and or calcination” etc there will be others.

If I recall correctly there is division within FFE in Australia who have experience with repair and delivery of LSTK (say) kiln projects, if you would like the contact, please PM me. I suspect there are other consultants with similar capabilities.

Can I respectfully suggest unless you really need to (or economics dictate) complete the reaction on site, you consider purchasing the product in its required form (in a ISO container et al)?

As you are probably aware, it is not a very friendly product / process. There are a number of reasons why you may want / need to complete it on site, which is fair enough.

I have worked in steel and in lime. Typically, the steel mill will want lower sulfur lime. Reheat kilns and shaft kilns tend to capture the sulfur in the stone which results in higher sulfur lime. Traditional "long kilns" make lower sulfur lime and have been preferred for steel shops. Some mills pay a premium for the lime from long kilns. The trade off is that long kilns are the least energy efficient, because the exit gas leaves the system at a higher temperature (over 1000F) Shaft kilns would be the most efficient, due to the ability to insulate them much more than with a rotating shell. All kilns are subject to the economy of scale, so be sure to check your economics carefully. It may indeed be cheaper in the long run to purchase from a local source if one exists.
