This one is an steam injected wood burner I designed and constructed for a machinery trader importer. This is meant to be use in conjunction with a rotary drum grain dryer. In a nut shell, base on our test and rough estimate we can save more than 50% wood. I will tell you more when I have the time, probably tonight. I just want to post it before I forget or worst change my mind. I intend to patent it before. But heck, the era of monopoly is fading its the dawning of the era of sharing:)
Ooopp s mp4 files are not allowed. So what do I post?

This is the first prototype of this kind. And still needs some revisions. But crude as it is, It is the most efficient biomass burner I have seen so far. The concept is simple and very easy to do. The trick is to effect steam cracking right where the flame is burning. This turns the bigger hydrocarbons (wood gas) into smaller bits so that it can be burned completely. I don't know the actual chemistry. I dont have the means to know. But what I know for sure is that we use far fewer wood with other test parameters being the same. This concept can be use to almost all biomass except perhaps rice hull which contains mostly methane fuel. Though I have not tried yet but I will try rice hull as well when I get the chance. My instinct tells me that water is burned as well.
So to the drawing. The red tank on top is the water tank. I pressurize it to 10 PSI before test. It has little water in it and mostly air so that pressure can be maintained. The tank has a !/4 inch copper tube (and ball valve) that extends down the combustion chamber and is coiled and rest on an X solid bar high enough so that the flame will not melt it but low enough so that the water that flows into it will turn into super heated steam before exciting the coiled tube. The steam hits the fire directly. This concept can be use on RMH and just any kind of biomass burner. The thing that I dont like with this prototype is the fact that steam injection is sporadic. Apparently when water goes to the coiled tube and turned to steam it creates back pressure and push back on the incoming water. So this needs to be fix. Perhaps some of you can do experiments and share with us. Right now I dont have what it takes to continue the experiments. Being in a third world country we are not as privilege to do the tinkering. In fact due to some constraint I have not yet started my propose bit gardening system which I have publish here. My first thread in this forum. I'd like to take this opportunity to thank master gardeners Bryant Redhawk and Daron Williams for sharing their knowledge without theirs it would have taken me years of schooling. https://permies.com/t/83651/Bit-Gardening.
Ok so back to topic. well, at this point I wanna hear questions and suggestions.
That feels good. Thanks. Here's a tiny ad:
