Bio Char Kiln’s for off grid wood gasifier - how efficient are they?

Bio char kilns are a great way to create the bio char and dry wood you need to feed your off grid wood gasifier. In addition bio char is GREAT for your garden we have heard of double the size and growth of plants.

Most bio char kiln’s on the market are of the open burn type. Where you burn the wood and let the char fall through a gate. In theory this is simple and works well. However, the char once it falls through the grate keeps burning. Most open burn bio char kilns yield 10% of bio char to wood burned.

A sealed bio char kiln is completely different. These units have a completely sealed (to the burn chamber) bio char box - this box is vented to the outside to let gasses and moisture escape - BUT NOT FLAME - comes in contact with your bio char.

Our system yields anywhere from 33-50% efficiency which is 3-5 times more bio char than an open burn kiln.

Our off grid wood gasifier kit includes a sealed bio char kiln.
