Description:
A laboratory-scale charcoal kiln simu-lator was constructed and tested to de-termine if it could be used to produce charcoal that was similar to that pro-duced in Missouri-type charcoal kilns. An afterburner was added later to study conditions for oxidizing the volatile or-ganic compounds contained in the com-bustion gases that are produced when wood is converted to charcoal. Five burns were conducted to shake down the operation of the afterburner. Then four full burns were completed to mea-sure the effectiveness of the after-burner. Based on these simplified studies on the effect of an afterburner on emissions from Missouri-type char-coal kilns, it appears that, while the af-terburner can offer significant benefits under some conditions, the operation of the afterburner is not a trivial matter. A system, such as a charcoal kiln, that relies on natural draft for operation may be upset by adding an afterburner due to pressure changes in the stack that influence the natural draft. Optimizing the process, both in the sense of good charcoal quality and good afterburner per-formance, may be difficult without the benefit of continuous emission monitors.
