Well, I used the new diaphragm pump for the first time yesterday. Much better than the old gear mesh pump. Oil and air temp was around 20 degrees F, pumping through a screen filter and hydraulic filter I probably get about 2gpm, unrestricted (no filter) probably closer to 5gpm. I'm happy with that, in the warm weather I'm sure it will get close to the rated 12gpm...

clipfirst draft of outdoor WMO furnace--What do you think?

Hello all, I am new here and I have a prototype idea for an outdoor oil furnace, the drawing is attached. I was thinking of having the bottom of the first combustion chamber removable for cleaning as I would be running unfiltered drain oil. I see a guy on you tube who makes burners out of fire extinguishers and they seem to run well. I am thinking I could insulate the inside of the shell with ceramic wool and have an insulated flex pipe ran through my garage window. The big blower that circulates the air would be attached off center of the shell so it swirls the air around the combustion chambers and exhaust pipes. I am thinking with 2 or 3 combustion chambers all the residual oil would have plenty of places to completely burn up and the only thing exiting would be carbon monoxide. the car muffler would contain the flame completely and act as another heat exchange.

Goals:
1. Burn unfiltered oil, so I would have to use wider fuel line. I could pressurize the vessel with something quiet like an air brush compressor for fuel delivery.
2. Preferably no preheating, with having 3-4 burn chambers. I could keep the oil supply in the garage to keep it a little warmer if need be.
3. No spray nozzles. I built a gun style spray burner one time, It worked well on the first batch of oil I burned because it was mixed with gasoline, but once it was straight waste oil, I couldn't get any kind of combustion what so ever. Plus, I don't want my air compressor running all the time.

4. No filtering, I would like to just be able to dump any crap in my container that is petroleum based oil that doesnt contain antifreeze. Its hard enough to get oil to burn in -10 degree temperatures that I don't want to have to spend more time screwing around with cleaning the oil, when I could just burn it, and remove the primary burn chamber to clean that.

Any after thoughts?

The easy way to check if the igniter is working is to lift it up while it is trying to fire. If it is good you will see the spark jump to the electrodes.

Ok, so I just checked my nozzle inventory...

The nozzle that was installed when I got the burner was a 9-2. I After a few days of frustration, wondering what the heck I was doing wrong, I installed the 9-31 and it's been working almost perfectly since then. I also have a handful of 9-5's which after a little research seems to be the stock nozzle.

So it seems that I'm running a slightly smaller than stock nozzle, which makes sense because my blast chamber is defiantly smaller than the original Clean Burn furnace.

Now that I think about it I'm guessing because the previous owner burned Vegetable oil he needed a smaller nozzle and that's why the 9-2 was in there, does that make sense?

Are nozzles something that wear out pretty often? I'm not sure how old the current nozzle is, but is it something I should have a good spare of?

Also, what is everybody setting their preheater temp to? The Clean burn manual says 150, but it seems to work better at 170.... I've read the over 180 and there is a high risk of carbon buildup in the heater.

Thanks,
Austin

I would go with the 9-5 nozzle. They do wear out over time but it takes 1,000's of gallons of oil running through them before they start to wear. You can take them apart to clean them if they get plugged. I do not run anything over 150* of preheat temp and you will bake the oil quickly especially with that burner having the oil element on the oil. The CB 4000 burner was short lived and the worst of all the Clean Burn designs.

Other than about $800? Just kidding, I'm going to guess that the pump is the main difference. As far as I can tell, and I'm pretty much a newbie to waste oil heating, there really isn't much 'new under the sun' in burning waste oil. Most all of the designs that work use a siphon feed, either from a constant level tank or a pump. Physical layout of where you want to use it will have a bearing on what you want to use, for me a tank wasn't really handy. Most people on here and on altfuelfurnace on yahoo groups seem to think the metering pump is the best way to go if you can afford it. The nice thing about the Clave pump is that it's adjustable, and with a metering pump the temperature or makeup of the oil doesn't effect the flow rate. I'm currently using a pump but with pressure regulators, and it does require a little tweaking during the day as the oil flow rate changes as it warms up and thins out. I'll likely go with a metering pump eventually myself, but a lot of the 'factory' waste oil burners do use the pressure regulated pump like I'm using now (mine is from a Lanair furnace).  From reading the Clave advertisement on Ebay, I do like the fact that the oil is not heating when it's on standby, but right now my setup is the same way, more by accident than design. That should make for less buildup in the block, although again, there are factory furnaces out there (my buddy's Cleanburn for example) that run the block heater anytime the furnace is powered. He doesn't seem to have any problems with his, and he bought it well used and has used it hard for three years now.

I suggest you talk to Craig and the Clave people, and explain exactly what you're looking for and see what they say. They each will know their products better than anyone, and that will give you an idea on what is best for your application.

Greetings MMDeveloper, welcome to the forum!

Sounds like you have some work to do with your tank.  Good luck with your project and stay safe!

Most furnace controls have provisions for oil solenoids that will turn on to allow oil flow to the gun when it starts to fire, and turn off when the control turns off.  Look at the wiring diagram on your main control and you should see terminals for the solenoid.

One more time, two steps forward and one back.  I put it all back together, using different leads to the heater, and I tried them with an extension cord with the heater in the block before I reassembled, and it works. I did notice a frayed looking spot in the cover of the thermocouple, and made a mental note to be careful that I don't mess it up because it looked like it had been pinched or something. Nothing like being a psychic, I got it all back together and no thermocouple action. Evidently moving it around was enough to separate the wires or something at that bad spot I noticed, so I'm dead in the water until my new thermocouple arrives on Tuesday. For good luck I ordered a complete set of new PID and thermocouple also, so I don't have to wait for parts if something goes south in the future. I did get work done on the tank and pump set up today, for lack of a couple little fittings that I need to get from a hardware store (and that I thought I had, but didn't) the pump and tank are ready to go with a new pickup with screen and check valve, and a Goldenrod water block filter in line.  Getting closer, not quite there yet.
