Is this a regular event? Are we talking large numbers of piles? The potential for large quantities of biochar? Is there a potential market for the biochar? What is the context now and going forward? That is, is there reason to invest time and thought and perhaps money in devising a workable, long-term solution, or is this a one off with no future? Or, even if it is a long-term problem, it's not feasible from a business point of view because there is no potential to cover the costs of solving it, paying for labor, etc.?

The piles are usually huge. 15-20m diameter and 5-6m high. Logs are 0.1- 0.25m diameter.
To make it worse , they burn when its cool and damp, outside of forest fire season.
The only partial solution i see so far is to make more pyramid or cone shapes and top light, then maybe bury hot ash with a bulldozer. Dousing with water does not seem to be an option because of the huge volume.
It depends on the size of the pile. I am currently working on a portable (as in, easily disassembled for transport by pickup), in-field unit that is 1.5 m x 1.5 m x 1.5 m. It can be assembled around a pile provided that the pile is not so dense that the chimney cannot be inserted.
Will be testing newest prototype in about 2 weeks (have national holiday to deal with). Photos and plans then if you like.
