This photo-essay documents about 2 days of experimentation that resulted in a pretty stupendous new variation on Max’s “Cabin Stove.” The overall footprint of the stove determined the firebox size, and the geometry resulted in a rectangular heat riser that took hot gasses from a vertical throat in the corner of the firebox — unconventional, but it worked amazingly well. More to come! (Ed. Note: This stove, like so many others, is merely one more in a long line of innovations and adaptations, all based on the same basic principles: burn the fuel fast, hot, & clean, and extract and store as much heat as possible prior to venting. Within this long tradition, however, valuable technical analysis and development has recently been offered by a Danish builder named Peter Vandenberg. His contribution have provided inspiration and guidance for understanding and improving the hows and whys of clean combustion. Peter offers comments at the end of the post, and is a regular contributor (along with Lasse Holmes) to an online stove forum at http://donkey32.proboards.com/.
