You are really close to max efficiency with your burner. Would bet you that maybe use a secondary air injection would make it the ultimate unit. Nice work fella.
yeah that helps I thought it was more like 1/2 in, boy was I off! I am going to do a T and start with 1/2 in off wall and 10 3/16" holes on opposing ends for the vortex. Also using am using couplers at the burner T and through the tank wall so I can make adjustments without cutting anything to dismantle. I ordered a 273 cfm fan and riastat so I can vary the air input. I am using a 30 gallon compressor tank and have a water tank as an alternative tank if needed.
Rob here again! I got my air tube started as a T and as you stated Ill set it up at 2" from bottom. As I looked at the T tube I saw that I have it horizontally with maybe a 1/4 inch clearance. I thinking that maybe I should have about at least 1" clearance on both ends. i'd show you pictures but this doesn't give you the option to add pictures. I should be firing it up in a couple weeks
I'm trying to visualize your 2 inch tube burner...and where the oil line enters...is the bottom capped off? Any build up inside 2" tube? Did you try air flow adjustments? My goal is to slightly pressure air with two small computer fans. less noise and less power than a blowdryer. A very nice presentation
I got a question... Why your Pipe (Air / Oil Feeding Tube) is straight down into the Flame. Most People would put it at a 45 Degree Angle so the Pipe doesn't get too Hot or Kill your Copper Feeding Tube. Is there a reason? THANK YOU !!!
Thank you for your question. I recommend you watch my previous video. I brake down a similar heater and show how hot the blower tube is. The blower tube never gets very hot because of all the air coming from the blower.
Hi, I think your 2nd Mod is a lot better :))). Have you thought about putting the Old one on top of the new one? Plug up all those Holes and put on top of the new one? Since you have a Welder, it will be easier for you. :)))))
Please share a link to the burner build. Do you have issues with coking in the oil feed line? Thanks simple strait forward youtube! I like your delivery.
Thank you for your comment Peter. I have another video entitled "My new waste oil heater" that goes into more detail on the burner unit. It was my first attempt at a blower driven heater. I have had no issues with my oil feed lines and I have run it several winters without a problem. I now pour my waste oil through a paint strainer before I load it into my tank. That gets rid of any junk that will eventually clog the feed line. The only coking or carbon build up is on the bottom brake drum. That is easily scraped off once a week. Good luck with your project.
Well NJ I got mine going and wow! good design thanks> I have only one problem I think, I cant get it to stop smoking, so I am still running to rich I think but I have just a drip going into it. start up gave me a blue flame then slowly goes to a smoky exhaust. I have 30, 3/16 holes on a T, inch and a half square tube. running @50 to 275 cfm and still smoking. any thoughts would be appreciated. also I'm 2" from bottom with the tube and about 1/4 inch off out side wall
Hi Rob, I'm glad to hear you are making good progress. If you have black smoke then you are running rich, white smoke is usually running lean. Is the inside of your burner getting loaded up with soot? What size chimney do you have? Can you make temperature readings of your burn chamber as the fire changes from clean-blue to smoky? If the sides of your burn chamber are not getting really hot, you might try taking the T out or, making a second straight blower tube to see if that make a difference. Maybe the T is cooling the sides of your burn chamber. Sorry I can't help you more without seeing it working. Try posting a video. There are many smart people here that could help with the diagnosis. I'm happy to help as much as I can.
hey nj good job figgering this out! ive been watching and planning for years and like like what you have done the best . I am in the process of building your design. I think you can you can get the blue flame with more air!? I am gunna use a water tank and put baffles in it to hold the heat in longer and bump the air to about 200 cfm and cut the holes of the blower at an angle to create a swirling movement
Thank you again for your comment Rob. I bought a larger 273 cfm blower but, the 75 worked so well that I never tried it. I also wanted to make a 'T' at the bottom of the blower pipe to get the air to vortex but, I never got around to it. Here is a link to a video by Ota Vapno that I really like. He has three videos of his heater and he gets a nice blue flame. th-cam.com/video/XbMZn6EnFgY/w-d-xo.html Good luck with your project!
I am currently working on another version. I bring the air pipe in on the side instead of down from the top. The vortex is awesome but, it doesn't get anywhere near as hot or, burn as clean. I think the forced air is cooling the brake drum sides too much. So far the version used in this video works the best by far.
The 1 1/2 blower pipe is exactly 2 inches from the from the bottom where the oil comes up. I tried raising and lowering the pipe and 2 inches produced the best flame. Also, there are no holes in the bottom of the pipe. Only 3/16 holes around the sides of the pipe. Hope that helps.
Harder to come by drum brakes nowadays. My burner Videos th-cam.com/video/PeyV490fGB4/w-d-xo.html Clean up of mine th-cam.com/video/StVJgbA7JII/w-d-xo.html I think I need more air but limited at moment and using inside heated air so until I get the cold air from outside make up air into the inlet fixed will run it low & slow.
excellent fuel miser results, the best that I have seen on any stove . Thank you for showing us your work.
You are really close to max efficiency with your burner. Would bet you that maybe use a secondary air injection would make it the ultimate unit. Nice work fella.
Look forward to see your new design and good luck to fella.
Nice work fella. Like your logical way of thinking. Peace VF

What state or city are you located, also I would love to buy a finished product

yeah the T is the way I was gunna do too! Ima using 11 inch drums and hope to get a good burn. Yeah that link, those guys are using a lot of air!!
Great video, what kind of smoke or emissions do you get out of the chimney pipe?
I am currently working on another version. I bring the air pipe in on the side instead of down from the top. The vortex is awesome but, it doesn't get anywhere near as hot or, burn as clean. I think the forced air is cooling the brake drum sides too much. So far the version used in this video works the best by far.
would you consider building one to sell?Also your heat exchanger pipes could blow into a duct system?
what did you use to drill out the holes with for the pipe
hey again! how close is your air tube from the oil intake? Ima guessing about 1/2 inch
The 1 1/2 blower pipe is exactly 2 inches from the from the bottom where the oil comes up. I tried raising and lowering the pipe and 2 inches produced the best flame. Also, there are no holes in the bottom of the pipe. Only 3/16 holes around the sides of the pipe. Hope that helps.
should melt fan soon

This design is way to noisy.
