Okay so I've been wanting to experiment with rocket heaters for a while, but I don't really live in a large enough apartment to do so. So I figured I'd ask about my ideas and see if anyone knew anything (so this is probably in the wrong place).
What occurred to me most recently is that most things that constitute wood ash are insoluble in water, so if you forced the pressurized gas to bubble up through a small water tank, I expect it would boil the water and shoot steam through the rest of the pipe, but the ash components would get stuck in the tank, right? And the exhaust port wouldn't need cleaning, just the tank, if my thinking is right. Furthermore some of the CO2 would react with the water to get CO3H2, which would in turn react with ash by-products like [Ca+2][O-2] to get [Ca+2][CO3-2] (about 25-45% of ash is one of those calcium products) and water, and some of the carbon would be sequestered as salt, I think. That reaction shouldn't have time to happen, but at the temperatures involved it may...
Another thing I'd like to know about is how the heat inside the barrel is. Like if it's mostly radiation then you could replace the top of the barrel with a bundle of fiberoptic cables, and direct the heat to masses around the house with minimal loss. Alternatively if it's mostly convection then you could add rifling to the inner pipe, and make the inflow off center to create the sorts of effects in a vortex tube, ( www.instructables.com/id/The-Hilsch-vortex-tube/ ). Is much known about the conditions inside the burn chamber?
