Try denatured alcohol as a primer. Much hotter and no flash burn. Will be interesting to see if the 308L can take it long-term. I have not had good luck getting any grade stainless to withstand extreme temps. Too bad you can't find some cast iron that would work. For the shut-off, I wonder if a sliding gate located at the lower end of the feed tube would work? It would have to be thin so it could work its way through the pellets. Sharpen the edge that comes in contact with pellets in case it needs to cut through a pellet or two. Instead of a plate, possibly use several pieces of thin rod welded together. Spaced apart so that pellets can't pass through while making it easier to get through pellets than a solid plate. Round the ends of the rods (not sharpened) to push pellets out of the way versus getting stuck in them. Just thoughts...

If you'd ever really studied wood burning in the firebox of a Rocket you'd understand. Fresh air rushing in from the top combined with the venturi effect of the wood itself in the firebox opening keeps the burn contained down low in front of the horzontal burn tube. Only of air stopped flowing completely (which never happens) and the pellets were good and hot might the burn start to propagate upward. Even then I'm not so sure because pellets really need a good air supply to keep burning. Wood chips on the other hand I might be concerned about.

I have done much experiment with rocket type stoves. I have achieved such high temperatures that my 1/4" solid stainless grate was burned through in the center of the grate in only 8 hours of burn time. Achieving high temperatures means more complete burn and less ash but also means you must use a material like ceramic or refractory cement as the grate material. HINT: to greatly increase burn efficiency - pre heat your intake air. Yes intake air needs to be drawn from outside but pre heating it to at least 200°F will give you an incredible burn that will almost never go out. I was pre heating my air to about 500°F and obviously it is physically impossible for the flame to go out when the feed air is over the combustion temp of the fuel. Next heating season I will start adding nails to my biomass briquettes and STEEL will become a part of my heating fuel...... just like in coal burning electric plants.

For the last few years, I have been using pellets coated with cheap ($6 gal) cooking oil to start my old pellet stove without a electric lighter. I am thinking cooking oil and a BBQ starter fluid mixture would work even better. The pellet stove manufacturers discovered very quickly that a gravity feed system can be VERY dangerous. You can get small cheap dirt augers, from farm supply stores, that should be easy to use to make a safer feed system using a small gear motor and digital timer.

I had another idea for controlling the pellet flow to the rocket; might make an interesting project as well. Consider constructing an external horizontal auger feed system. I don't think it would need to be any longer than 6-inches. Since it would not be subjected to extreme temps, it could be made of PVC pipe. A PVC Tee would direct pellets into the PVC auger tube. Auger motors are relatively inexpensive off ebay. You would need to design and build a small auger and a variable timer system to pulse the auger motor. When you turn off the auger, pellet flow to the rocket would stop. Since there may be only and inch of pellets in the hopper at any one time, you might have to add a baffle plate to maintain proper air flow through pellets. The variable timer design would permit you to control the amount of heat being generated by the rocket. Regards.

What is the quantity of pellets consumed per hour? Is it still as efficient as with wood sticks and such? Wood pellet stoves have a fan that extracts the smoke away, and i understand how you are doing your best to make this off grid, but if you had some sort of auger to control the flow of pellets into the crucible and then directed the air flow down directly on top of the pellets to get the Venturi effect for complete burning. I am betting that you could Make a flow control at the bottom of the tube like what is found at the back of a jet boat output tube so that it is still gravity fed. Made out of cast iron to withstand heat and just high enough that it doesnt get hot enough to ignite the pellets in the tube.

Attach this motor to your feed tube. Build a 555 circuit to pulse it 5 seconds every 30 minutes (adjust timing and fiddle fart around with the voltage to optimize.) Re: Your 308L stainless basket: Not good to weld the lateral rods in more than one spot or the 308L will expand/contract till it self destructs.

This vary interesting. About two years ago I built a mass heater, rocket stove combination. The firebox was directly into the mass with a inverted 15 gallon barren heat exchanger in the exhaust exited from the storage mass. From the heat exchanger then into a free standing masonry chimney in my shop. I used it for two winters inside of my shop, then learned my insurance would not insure a home shop with a wood stove in it. Nor would they insure my house which stands adjacent to the shop containing a wood stove. I have removed it and used the 980#s of broken brick and mortar to go into the foundation of a concrete slab. I have tried several methods of operating that masonry heater on wood pellets. I am vary interested in what you have done here and see many possibilities. The masonry part of my heater was similar to those seen at this youtube link, Rocket Mass Heater Stove Wood Refractory Masonry Hermon Heater I must say the mass is the great advantage of this type of heater. If anyone has a suggestion about home owners insurance that allows wood stove in home shop I would be happy to hear of them.

As soon as the twisted one is lit, I push to back to the riser section to get a draft started and close the clean-out access door. Then I can use a long lighter to light the balled up pieces that are waiting on top of the pellets. Starts up very well.

For better feeding of your pellets, have you considered truncating your tube feeder? That means to make it smaller at the top and larger at the bottom. Perhaps this could be accomplished by leaving the bottom round, and slightly flattening the tube more and more as you go up to the feed hopper hence reducing the volume. Perhaps this would reduce any clogging.

Have you tried to burn wood chips- and by that I mean the tree services now put lots of the wood they cut down through a chipper.

I had thought if I had a bucket of chips and wood start the heater going with some sticks/ limbs and then take a small ice scoop and drop them down the throat of the feed tube they would burn ok. I am thinking I would need a little grate or stand at the bottom so air would flow but other than that I am thinking this should work. I would have to feed it often but my heater is only supplemental ti cut down on fuel cost while burning up basically trash. Anyone else had or done this idea

Some have tried and it does work. The problem is keeping them from jamming up. They tend to clog very easily whereas pellets drop much more easily.

At the same time, this won't harm the stove. - use a larger diameter tube that is smooth on the inside to prevent binding pellets. - A bigger hopper might be a good idea - put a shroud over the fins and put a small electric fan to blow air past the fins to double to output of the heat in the room. - Find a heavy duty spring to use as your cage for the pellets. Weld a plate on the bottom of it and drill holes in it. That should last a LONG time before needing replacement. I hope this helps. Please tell me what you think.

Zero, Have been following you since the OH days. Had a lawnmower running for awhile strickly on a plasma setup, no electronics. On your pellet stove, placed your pellet hopper in the firebox from corner to corner to start the fire. Have the front balance arms sticking out of the chamber through a slot, such that when you have it started you can move the arms to the rear making the hopper closer to the back of the fire box. Could label them start position and run.Slot being large enouogh for the arms to stick out should not create an accessory draft. Need to add a clean out door on the steel enclosure so you can clean it out without dismantling the unit. Make it the size of half a brick. Make a mini hoe to pull the ash out with. Should be big enough Bill

I see you have the air intake above the burn tube, just curious why you went that route instead of connecting at the same level. I'm building my first rocket stove and had planned on having my air intake at the same level (but in front of the stove), and routing it to the floor like you did.

To start, GREAT JOB!! I'm new to this, and have a couple of things to think about.... One problem seems to be controlling burn.. As you point out, its getting too hot in the shop... Damper on your exhaust maybe? Or how about damper on your intake (I notice that you use air from outside (burning cold air better than warm air.)). My concern with both of these damper options would be CO... No other videos online mention it. Given its lethality, it is well worth considering in such a restricted area... Another way of changing the heat being produced could be changing the dimensions of the burn chamber (on the fly)... This would take some fairly major rethinking of how the chamber is built... But not impossible... Your forethought on the design facilitates this. That is, from what I have seen, I think you can change/swap out your burn chamber. Also, starting, Rattlerjake1 suggests oil, I like where he is going with it... Smell, and safety, maybe a consideration... Another option would be a access door/hatch through the side or front, that can be opened and closed, this would let you have access to the burn chamber easily. Your project really is inspiring. Thank you.

Bart Wilson Damper on the intake would work better because it would create negative pressures inside the stove and prevent gas leakage. I also slide the pellet fire basket back a little to let air pass in front of it. That cools down the burn and regulates to some degree.

You should try a second bottle inside the first bottle using the top portion to create an inverted cone with a small opening around the outside of the cone. That way the entire weight of the pellets in the bottle are not forcing the pellets into the pipe and stopping it up.

Gravity feed, no power, REAL COOL!!! Until you had mentioned it, I too was thinking about the life of the burn grate as well because my wood stove (which has a bottom feed air supply/ash pan) needs a new one about every 3-4 years because of the exposure and conditions. In the rocket stove it seems as if this is going to be much more extreme conditions because the pellets are burning within the grate material. I was also wondering about life using SS. It could be better but it still may take a beating being exposed to the hot coals in what is realy like having a constant blacksmith with a never ending bellows. I have always wanted to try something like ceramic rods fabricated into some sort of grate for my stove. Fragile but I would think they should be able to take such extreme heat. Every time I need to replace my grate I think of maybe trying something like that just to see if the life was any better. Maybe its worth exploring here? I'm also curious, is there any major difference in your stack temp using pellets vs. wood?

I'm wondering if you couldn't place the hopper in it's optimum position & start the pellets using some tinder placed behind the hopper. I would think the coals generated from burning a small amount of starter would catch the pellets. Are you going to come up with a biomass production to make the pellets? Have you looked at possible making biomass briquets that have a hole in the center. Then stacking them on a rod. The rod placed on an angle ending in the firebox of the stove. To allow auto-feeding of the fuel without electricity. Just some suggestions. LOL Thanks for the vids they're always well done.

The best method so far seems to be just place a small amount of pellets in the very bottom of the grate, soak with some lighter fluid and ignite with kindling from behind as you suggest, then start the flow of pellets once the bed of coals is well established. I can also cheat and hit it with a propane torch for a few seconds.

So you went from burning FREE easily obtainable material to having to BUY pellets. Have you thought about making a drip waste oil tube into the fire box once you get it running with wood? The heated air flow would be more than enough to keep the oil burning and it would be easy to cut of or adjust flow to adjust heat.

Outside air inlet rather than pulling air from the room which creates negative pressure drawing cold air into the living space. Makes the system much more efficient. Workshop is elevated so it was easiest to just go straight down through the floor rather that back through the wall. Both would work.

I posted on T2H's channel and the new forum regarding my rocket stoves performance and some crazy but interesting ideas. Hope you see it. My prototype burns sticks and/or pellets, but sticks don't come close to performing like pellets! My latest pellet chute mod is burning close to 8 lbs. an hour through a 3 1/2 inch riser, but that leaves no room to burn anything else at the same time but smaller sticks. What a sound!! Can't wait to cook supper again tonight!! I have no back burn into the hopper in spite of vertical gravity feed, and it's natural draft. My burn chamber evolved into a modified, 4" x 6" J tube at a 25 degree angle, with a short vertical section near the mouth for the pellets. The 3 1/2" riser is carbon steel exhaust pipe, but it and the 1/4" wall sleeve it sets in are *orange* *hot* when burning 6 to 8 pounds per hour...upwards of 1500 degrees F! Even at half that burn rate the top of burn chamber and the riser get a dull red. The pellet chute and SS burn screen are at about a 30 degree angle, hugging the ceiling of the fuel chamber that I burn sticks in. The stove guts are inside a grease drum, with perlite filling the bottom and insulating the burn chamber only, giving me an oven area around the riser. The riser passes through the drum top, enters a 50+ pound heat exchanger box where it is forced to go horizontal for about 12", then exits down thru a heavy wall 4" tube that connects to flue pipe. No can on top, more like KB's Omega Stove. The trick was finding the right Stainless mesh (.047 x 3 x 3) and the right angle so it would feed smoothly and fall through the mesh at the right rate. If I ever stop improving it I will get a video up, but I am striving to burn sticks and pellets simultaneously, so I can tend to the fire on *my* terms. Like I said, the 25 degree angle evolved by accident, so my next one will be a 45 degree angle, since sticks will not self feed at 25 degrees.

ZeroFossilFuel I'm taking a lunch break from reworking my outside air intake to larger cross sections. The 8 lbs/hr happened when I just had it tacked on to the burn chamber with lots of leaks. When I mortared the cracks shut I had to run it with the door open to get enough air! Apparently it was leaking way more than I figured. Last night I put in my 4 lb/hr chute, but with leaks fixed, it would not take off with only outside air. I slid the chute a mere 1/2" closer to the riser outlet, which left it intruding into the opening that same 1/2". That got it burning 2 lb/hr, until I holesawed 4) 1" holes in my air ducting, just to see where it was starved. Then it burned 4 lb/hr like before and gave me insight to correct it. Before I am finished I will have my pellet chute so it adjusts up & down the chamber ceiling, nearer or further from the riser outlet. I don't know how to work links, but will try to get some still pics on the forum until I get this thing ready for video. (My stupid smart phone is deactivated till I can afford it on $1200/mo SS) This shit's addicting!! Thanks for your acknowledgement!
