joash480: does it last and burn better than ordinary wood sticks?
peterinbrat: You need a secondary air intake or it's not really a rocket stove. The idea is that you are getting better pyrolysis with the higher heat AND a secondary combustion. That's why with the L burner, you are suppose to have a plate below the fuel feed so air is sucked into the burn chamber. Lot's of designs out there for rocket stoves that are not really understanding the concept. If you overload it, it should be flaring out through your fuel input.
Try feeding a two inch high temp hose in through your fuel feed.
momentsbigadventure: what video editing software did you use to add your text?
mozaikadezign: I own a pellet wood stove, black smoke is not enough air flow, opening the damper a wee bit solves the problem. I also noticed on mild days that there is less air flow coming in even if the damper is untouched, cold days no black smoke build up on the window of the stove.
Joseph Busch: if there is too much smoke you need more air
glenn connell: I would have thought the fuel needs to burn before the vertical stack so that the fire can mix with the fumes when it hits the combustion chamber before rising vertically, hence the need for a horizontal filler tube
Marc-antoine Droguet: Bravo
exclamation3mark: need this with 50 litre water heating capacity for bath added manually by buckets
exclamation3mark: great piece of kit
lebammabel: Air enters space between both chimneys at the level of burning chamber and while travels up to holes gets some preheat.
Bristol Rocket Co.: This means the air is not heated up before is injected into the chimney?
lebammabel: If you mean side holes which appeared in stove update - I inserted tubes which connects outer stove body with chimney. And some air goes through additional air intake beneath fuel feed tube (square one).
Bristol Rocket Co.: So the air is passing through the insulation in order to reach the holes you made into the chimney? Is this true?
lebammabel: Yes I used something similar to vermiculite which translates as slag or dross. I mixed it with heat resistant or stove clay. I must say that it is not best choice for portable stove but at that time I did not find anything better. It appeared to be too heavy and stays hot long time after burning. Good choice for heater. Next time will try something like stone wool.
Bristol Rocket Co.: I remember now you wrote to me about the 45 degrees burning chamber. I believe I was one of the first to make the rs this way. I used to have a youtube channel called bs4872. Your stoves are great. I have a question, do you have any insulation in there? Thanks.
lebammabel: Updates 2 and 3 of this video I think are a bit nicer. Here I have some combustion problems which seems to be solved now.
Bristol Rocket Co.: Very nice!
lebammabel: In this video stove doesn't have the secondary air intake. However extra air could flow into burning chamber through ashtray opening, but then ash removal will be quite uncomfortable. The secondary air intake I made later. You can see it in video - DIY rocket stove - gravity feed (update).
yutjub123: where is the secundary air intake?
