Has anybody experimented with different nozzle sizes? I'm still running the Hago siphon nozzles; but I recently purchased 3 different sizes and have been experimenting with them. I've found that I have a quicker light up, less "initial" smoke, and a generally cleaner burn using a smaller nozzle...

Since I have a large storage tank, I never burn any one kind of oil. There is always "mostly" Chevron Delo 15W-40 conventional oil in there. I have burned a fair amount of synthetic, but never noticed any difference in the furnace operation. As others have suggested, try raising your nozzle...

While I can recognize the need for an agency designed to protect the environment and health of the general public, the EPA is not my favorite organization. Use one of the EPA mandated "safety cans" to fill up the fuel tank on your lawn mower, and when you're done wiping up all of the spilled...

I was a little bit hesitant to post this; but figured I should share my failures along with my successes! I've been running my current furnace in my shop for many years now with relatively few problems. Thousands of gallons of oil have passed through it without incident. A few weeks ago I...

I still have my shop furnace; it is running right now! The last conversion that I did was for a friend of mine...I no longer have that furnace. I am working on a boiler, however at this point it is mostly just a pile of parts. I stumbled into a HUGE surplus of firewood this year, and...

Thanks! Yes, the principle is no doubt universal...I'd say that the nozzle block that Craig Kepner machines is probably a good jumping off point for ANY burner, though it is less work to install in a Beckett. I think that the most important temperature is the oil at the exact point that it...

I agree; there are far worse offenders than the handful of us who are building our own furnaces...but that doesn't mean that somebody won't cry "wolf" and shut our projects down.

**** :argue: I actually don't think this is bad advice. I do have a disclaimer in my very first post in this thread, citing local and federal regulations. My setup works well for my situation and location...it may not for others. Agree with the laws or not, I would suggest that nobody post...

I agree with this; but would add that, if you enjoy building cool stuff (like I do; and hour in the shop is way better than an hour on the couch watching TV) then this is a very rewarding project! I built a few versions of waste oil burners before I worked my way into this design, and I enjoyed...

I can speak to 3 different successful local furnace conversions. Other than a few cleanings and minor repairs, all have been relatively trouble free. I will say this: Don't assume that you can just throw the parts in the furnace, hit the thermostat, and walk away. In each conversion I did...

Thanks! I do seem to attract a fair number of "safety sallies" with my videos... I'm all for safety, but I also know that I might trip and fall on my way out the front door in the morning. That doesn't mean that I should stay in bed all day! My normal occupations have me hanging off the edge...

I found one of these slave plugs at a surplus dealer. I have a few military surplus generator sets that also have the same slave receptacle, so I considered purchasing one of these cables but the price was more than I was willing to pay! It is a cool feature, but I hope to never be in a...

Thought I might bring this thread back to life...in case there are any new(er) members who might like the info!

Chris, welcome to the forum! I am working on a boiler right now too, although I haven't wrenched on it for a few months... The blast tube needs to be long enough to house the nozzle block. The one that I show at the beginning of this thread could be an inch or so shorter, but not much more...

No reason...years ago when I built my first one, it was the best siphone nozzle I could find that was suited to my project. There could certainly be better or cheaper ones out there...

Yep; "genuine" pid controllers are usually more than $200. I did find some forums where electronics gurus were modifying the knock-offs for added reliability, features, and functionality. But...my feeling is that a $15 temp controller is a throwaway part. Keep a spare on hand, run it until it...

Sorry for the delay in getting back to you; I'm on a mini-vacation and out of my shop! I actually used two of those REX-C100 PID controllers in the last furnace build. The ebay ones are Chinese knock-offs...the included instruction manual doesn't work. Unfortunately, that furnace is no...

Where did this story originate from?

Are you asking for suggestions on how to remove antifreeze from barrels of waste oil that you are obtaining? If this is the case, it isn't too difficult. Antifreeze will always separate out from the oil and end up at the bottom of the barrel. Tip the barrel at a slight angle and run a rigid...

I'm not sure about the nozzle that was installed on my test furnace; it was about 75,000BTU. I never had a problem with the pressure nozzle clogging during my tests; it just didn't adequately burn the oil if I was over 30% WMO in my WMO/HHO mix. I wanted to burn 100% waste oil without mixing...
