Nice to see the positive effect of starting up and shutting down with diesel. Personally I think better filtration of the waste oil will be the biggest next step into a cleaner burning heater. Going to a 50/50 mix diesel/waste oil should also improve the burn. Maybe you could try to digitally control the valves you made, so it starts on diesel, stops on diesel and runs certrain amounts of time on the w.o. mix and then a certain amount of time on pure diesel (to clean the burn-chamber). Anyway, nice progress, and keep those vids coming!

Thanks for the comment. I haven't made a video about it yet, but I have recently tested new quality oil to determine if it is the oil that is the problem, or the waste in the waste oil that is the problem. Filtration is part of the puzzle for sure, but the largest hurdle is the temp required to burn waste oil / getting burn chamber hot enough. I was talking to someone the other day about your idea of electric valves that were timed to come on and clean the junk out... I went as far to suggest that a person could use a CO detector to judge when the oil starts to burn nasty and switch over to diesel, instead of just using a timer.... tho a timer is likely the smart thing to do.

I found Red Devil gasket cement and stove sealer. Going to try that for mods to burner...available from big box store Men ar ds. May be useful. Additionally I have had good luck with stainless steel screen material in the burn chamber. Can buy in sheets many places. Can cut and roll to shape and mod the burn screen area as you want.

Running my heater hours upon hours with a mix 80% diesel and 20% clean waste oi. I only had a really tiny bit of build up in the burn chamber. You can hear the sound from burning if it burns clean or not. Then i started to use clean diesel at start up and shut down. When it´s been burning thrue the whole night you can start to hear a bit of the not so clean burning noise and then when you shut the mix down and open up with clean diesel it starts running completely clean again. The more oilmix you put in to it the more often you need to pick it apart and clean it so i found the 80-20 mix and maybe even 75-25 mix favourable due to low maintenance. Going to start it up this winter as well for more fine tuning but i think im close to the sweet spot.

Hello and thanks for the comment. When you say "clean waste oil" are you referring to waste motor oil, or a cooking oil ? I do agree... if you listen to these things enough, you start to hear when things aren't quite right. I have tested with new motor oil and all sorts of different mixes. I would like to repeat some of my testing.... That being said, I haven't tested anything over 50/50. This is different depending on your situation, or what area you are in but where I am, even at 50/50, it makes more sense just to burn natural gas. Of course, IF you are already forced to burn diesel / committed to burning diesel, then 10% waste oil is a 10% savings ... If you are burning natural gas where I am, burning 50/50 oil/ diesel is a cost increase.

Having made the comment below, I just noticed I watched 11 yesterday and mist 10.5 for some reason...... Any way can't wait for the next video. Great videos, been watching since December and learnt a lot from your tinkering. I was thinking of separating the air fan for the combustion from the fan of the hot air. Just by adding an extra fan in front of the air intake and remove the fins of the original one. So I can change speed of air-intake for the burn chamber together with the pump pulse to get better fuel to air mixture. And then have the new fan keep the burn chamber at a more consistent heat by changing airflow. Maybe I'm in your words an idiot to and someone is going to say this is a stupid idea. But I'm willing to try it in the near future if you or someone else hasn't done it before me. Or can convince me not to do it with a good argument of course.. Again love your work and can't wait for number 11 and onwards.....

While aluminum melts at a fairly low temp, it is also really good at getting rid of heat. This is why it is used in pistons. I have determined the temp in my chamber is around 1000C, but the cold air coming in cools off the area where the oil is injected.

Thanks for the idea. I kinda started to do something similar to this, but my heater would overheat when switching back to diesel. This probably means that it was "working" as the extra heat is from the oil being burnt off by the diesel. I gave up on it after my heater overheated 4-5 times and happened so quickly that I didn't film it... so it didn't even make for good video. When the heater shuts down from overheating it takes about 10 minutes to cool before you can restart it, and then it would try to overheat again... it was a LOT of effort. This makes me think that this could work if I had electric valves on a timer that switched much more frequently. If I had more funds and more brain power, a CO detector on the exhaust that detected when the oil wasn't burning clean and switched over to diesel for 10 minutes...

I would have expected that you would need to reduce the viscosity of the waste oil down to that of diesel which means blending with something thinner than diesel such as gasoline or kerosene. I would use an airless paint spray gun "gravity cup" to check viscosity.

@loweredexpectations4927

8 ай бұрын

The viscosity isn't really an issue here. The type of pump that these heaters use displaces x volume per pulse, and the quantity of fuel is determined by the number of pulses. The only way viscosity would affect operation, is if it was so thick that the pump could not displace the oil. This would be obvious as the sound of the pump would change and the heater would likely flame out. With many other styles of pump, viscosity would absolutely be a concern, or if the system was pressurized and used a nozzle, but that is not the case. Mixing with diesel or kerosene is a good idea because it lowers the flash point of the oil.

Thanks for the comment. The burn chamber itself is pretty much as long as it can be without hitting the end of the inside of the heat exchanger.

One of the major struggles is keeping the temperature of the burn chamber up where the oil / fuel enters... I have a thermocouple on it now and have been doing lots of testing. I received a new controller today that will allow me to make fine adjustments to the fuel and air independently, so hopefully that works.

I've been failing at this as well. Using 6qt from my tdi, thin 0 wt oil that definitely has some diesel in it. Tried straight up, it ran but was very hard to start. Now I'm 50/50 and still struggling on starts, to the point I'm about 80/20 and it's not staying lit now. Thinking time for clean out. Frustrating because I havent ran much thru it. I hear the biggest trick is getting the oil clean. Using a centrifuge. Haven't tried yet, will probably just stick with diesel as I don't want to burn down my garage with the exhaust gets soaked with u burned oil and ignites.

I'm running a thermocouple on my burn chamber to monitor the temp where the oil goes in, and I can say for sure that keeping the temperature up is the biggest struggle. Once that is taken care of, then filtration will be the next hurdle. If your heater struggles to start on diesel, or makes funny noises on diesel, it is almost certainly a build up of carbon between the baffled area and the shelf inside the chamber.

Not to sound like a know it all, but these heaters use a MINUSCULE amount of fuel. They pump .022 ML per stroke. At max 7 hz, that means 9 ml (two teaspoons) a minute. To make a 5% correction to 9 ml per minute, you would have to reduce flow by 0.45 ml per minute. You would need an insanely precise valve for this to work, and even a slight temp / viscosity change would throw it way out of whack. This is the reason why they use dosing pumps with a fixed displacement, pumping at a specific hz to control fuel feed. You have almost infinite adjustment this way, within reason.

You would ideally have a thermostat controlled relay with a arduino or something that was smart enough to detect a flame out. When these heaters flame out, they keep pumping and running the fan... after the temp drops enough that they realize the flame has gone out, the pump stops and the glowplug turns on to burn off the plug .... BOOOOOM ! haha... So, Ideally you'd have a circuit that detected flame out in the burn chamber and shut the generator off immediately.

A 280 watt heating element in the chamber to flash off the oil may be a better idea. I'm not a chemist, but when you burn HHO it changes back into water, using up all of the H's and O's. This wouldn't change the air fuel ratio at all. If anything, it would make it run more rich, as the volume of HHO that you pump in would be displacing air that would normally be used to support combustion.

I’m glad you found this strategy used by me to be useful. You should still consider insulating the steel line that leads to the injector from where your brake line ends. This is to prevent the fuel you heated to cool back down again before being injected. If you also encounter vapour lock problems, or where your burner operates irregularity due to fuel being injected in different state phases.“ sometimes as vapour and sometimes as a liquid “ try to keep al the fuel lines going from bottom to top. This should encourage any vapour pockets to move along out the way and into the injector. Btw have you ever tried to run the burner facing down “With the hot air outlet facing straight down”?? I have a feeling this might encourage more heat to remain at the start of the combustion chamber as heat rises, and most importantly resolve or alleviate the white buildup you got. My idea is that the buildup always occurs where the unburdened fuel lands, hence it’s always in the bottom portion of the cylindrical burner tube. By running the heater pointing down this “fuel & combustion unburdened residue” will naturally fall down on to the heat exchanger part, in between the fins. Here the manual cleaning process will be much easier, being further down it will be exposed to greater temperatures so it might burn away all together and if not at least it will be in a less critical region of the burner where it will not affect the flame dynamics as much especially during the delicate start up phase. ;)

I do filter my oil, both in large batches before putting it into the fuel tank, and I also have a inline filter on the tank.

I reckon the perfume smell is some gasoline. I am fluent in recognizing rich exhaust as well I carry a gas can - AND a fire extinguisher; in my work truck. I have to vent the windows or the aromatics in gasoline are very strong when getting in the car. I don't know the exhaust gas profile of gasoline, but I think it involves a lot more CO when you don't have a catalyst. I've seen some videos on "black diesel". watch?v=DGTcGOmAbKM A blend, 30% fresh diesel 70% waste oil. But the key is, they run it through home water filters. I think 50 and 10 micron. It's the contaminants that create deposits, so the more you can filter out the better. I really want to share a video of my exhaust heat recovery, but as mentioned in the last comment, my fuel pump is not operating. I have a rigid dryer duct set to pick up the exhaust out of the muffler, set on concrete. Temporarily use a pc fan to induce draft until the chimney warms. Then move the fan to blow over the chimney to extract the heat. It exhausts directly outside from there. The highest temp I recorded without a process fan, just sitting in the air, was 130F on the black plastic pipe the chimney converts to before passing through the wall. If you direct vent you might have less exhaust issues, but also lose some of the heat that is recovered from the ventilation/attic.

Haha... yeah ... I'm familiar with the smell of gas and rich burning gas fumes. I'm not a big fan of it at all... I have seen a few videos of people claiming to burn waste oil in a few ways, but never anything convincing.... I tried to view the link but it didn't work ... I think I've already seen it, and if so, the guy hasn't posted a video update about the heater since Dec 08 2022. In the comments section he says he was doing modifications to the burn chamber... He's using 2 house water filters and has a very tidy setup with the heater over the black diesel tank. Yeah... eventually I need to direct vent... The way I do it is not ideal... but it's also nice to be able to see the smoke / exhaust without having to run outside to see how it's running.

​@@easymac79 Yeah... that's the one. I hate being like this... but I'm pretty sceptical of anyone who says they have done this without issue for an extended period of time. The soap creek guy says he's been running black diesel since October 2022, First video shows up Dec 7, then two on Dec 8th.... Then nothing ... My guess is that he said he wasn't having any issues and now he's embarrassed or too prideful to show what really happened. I have burnt new motor oil, and so I know that it's not just a matter of the oil being clean. Oil requires a much higher temp to burn than diesel, and even when it burns "completely" it leaves behind ash and additives. My testing continues.

Thanks for the comment. Waste motor oil has a few properties that are undesirable. One is that it has a much higher viscosity than diesel, but the main issue is that oil has a much higher flash point compared to diesel. Typical motor oil has a flashpoint of over 200C up to 260C for a good quality oil. The diluting is done to try to lower the flash point of the oil so that it will actually burn.

Well, mate, I bet that you're a terrific guy. Unfortunately I must admit to giving all of your videos on the diesel heater a thumbs down. I have not commented on any of your previous videos. You've contacted KZread to get monetized and I feel like contacting KZread to have you pay anyone who watches your presentations. You began by saying that so many KZread creators make copy-cat videos. Right then, you certainly can't be accused of that! Two important statements you regularly make are: Don't do what I do- I'm an idiot. And, follow the manufacturers instructions and burn the right fuel. A proper detailed review of assembling the unit and testing it on the correct fuel is of great value. I have benefited from many such KZread presentations. I expect in your next video you'll be running the diesel heater on a mixture of kerosene, rubbing alcohol, Vaseline, and perhaps even pissing in the tank after a good night of drinking. I live in Ohio, USA. Should you ever decide to pass through or come to my state PLEASE issue a warning beforehand...

Thanks for your comment, Jack. When I purchased this heater, I planned on doing one video just saying "hey, I got a heater". This is my secondary channel where I just posted crap... If you look back, you will see there is random nonsense. I think perhaps you misunderstood my comments about other KZreadrs and their videos. I don't particularly like cookie cutter unboxing / review videos, but I understand the reason and appeal... What I have a problem with is all of the people who are claiming that you can burn waste oils without any issue ... Posting a heater video was not priority, so it was delayed several weeks after I got the heater... By that time, I had experienced the horrors of what it's really like trying to burn waste oil, and decided that I would make a few videos showing my struggles. I have had a lot of comments from people telling me that they have had the same struggles, and also others who have told me that they were considering purchasing one of these to burn waste oil, but now they won't, because of my videos... so that's a win. If VEVOR ever sends me the heater(s) that I thought they were going to send me, then I 100% plan on doing much more practical testing, but this heater was purchased specifically to burn waste oil and I will continue the testing with it. I appreciate your insulting humor. Cheers.

Hey. Not sure how many videos on this series you have watched, but you're missing the point. These are great heaters for burning diesel. That's what they were intended for. There are people who claim they will burn anything, and this leads to people purchasing them with the idea that they will burn anything... My videos are to show the struggles in burning waste oil. Partnerships between KZreadrs and companies is simply about the number of products that you can sell for them. They don't care if I use their heater as a stool. I made a mistake and only posted the Canadian affiliate link in my earlier videos, and as a result lost a bunch of sales. (didn't get credit for sales). So, Vevor may not send me anything.

Жыл бұрын

Thanks for the suggestion. I have been trying most / all of my tests on alpine mode, but I don't show it every time as I think people get sick of it. Every time I test in alpine mode the temperature goes way down and it actually works worse. I think there are actually 2-3 issues with alpine mode. 1. It leans out the AFR too much and makes it run lean. 2. diesel and oil actually run quite hot when running rich 3. Overall, even if it starts to burn better in alpine mode, the overall heat output (BTUs) are too low to keep heat in the burn chamber, so it doesn't get hot enough to burn the oil and fouls up more quickly.
