Hey guys and gals, I invented this RMH stove. I use a high temp refractory for the burn box that is typically reserved for foundry use. It is denser than soap stone. when cured at high temperatures above 1500 degrees it's fracturing strength is almost 20000 lbs. per square inch. Its normal operating temperature is between 3-4 thousand degrees. I regularly record temperatures of 2800 degrees in the back of my stove.
I use the insulative properties of aircrete as an energy containment apparatus. It keeps the heat energy where it needs to be and lets it be released into the home when it needs to be released. I also use aircrete in the double wall stove pipe to maintain a hard flue at very low temperature as most of the BTU energy is expelled into the home. It exhausts out of the chimney at just over 100 degrees.
I moved to an off grid property specifically for the purpose of living with this stove. My jaw is on the floor on a regular basis. I had no idea what I had created. Watching this thing burn has been incredible. Winter came early and my cabin is unfinished and uninsulated. This stove really has been a life saver. We are in the rocky mountains of north Idaho and our cabin is 1600 sq. ft. The amount of BTU's that this stove can extract from just a small amount of wood is amazing.
I have read all of the posts on this thread and I must say I am impressed with the knowledge base. nothing was posted that I disagree with.
Here is what I have found. When I burn a fresh cut soft Oregon white pine with its low density (33-35 lbs. cubic ft.) It holds way too much moisture to maintain (HTSE) or hydrogen production. When I burn soft wet wood, I have to add 25-30% dry wood to maintain (HTSE) hydrogen production. However I have multiple Groves of European plum trees on my property which is a much denser fruit wood at (58*60LBS. per cu. ft.) and the higher wood gas compared to moisture retention in harder woods does allow it to sustain (HTSE) hydrogen production independently without adding any dry wood. Hard woods will maintain the burn box temp between 750C and 900C which is the sweet spot where (HTSE) happens.
I will be posting a video on my you tube channel of burning a fresh cut tree for 8 hours. It is incredible to watch a log in a hot box appearing to not be burning with a white greenish blue flame roaring up the back of the stove. it will be posted in the next couple days when the book is finished and up. Pretty cool.
