Charcoal

Thanks for the comeback of last night.

 

I would like to respond to the "sounds expensive part"

 

If you consider that only what is considered a " waste" material is used for charcoal. Forest companies in B.C. replant where they log, so this is a renewable resource. From internet studies we see that sometimes as much as 30 % of the char product is lost to burning. With our closed system ( Very little to no air getting to the charcoal) The burning problem has been eliminated. In terms of

the gasses, as I mentioned before, the condensable are turned into solids, and sold. The non-condensable, are rerouted into the burn chamber and used as axillery fuel. We have added a air system with the N-C gas to force the CO into the burner. With the right mix of air, the CO should burn. So in term of using renewable feed stock, our expected char return, saving the wood oil, burning the N-C gas, and most important, the benefits to our precious Globe. I believe our plant will be the most environmentally friendly charcoal plant anywhere.

 

The following are the expected products of combustion. Note, only because we don't have any charcoal to use as fuel for start-up, we are using a light oil burner. This will be changed to a charcoal burner when we have product.

According to the Scientist that did the numbers, and the Professional Engineer that put this all together for me, and I quote

The emissions will fall within the acceptable regulatory limits
