Commercial Waste Oil Heaters / Re: Reznor ra235 ignition issues.
« on: November 30, 2020, 04:52:26 pm »
So determined 250 gallons of bad oil. Rolled a different drum of used oil over and stuck the hose in and cleared all the lines and filter. Reprimed out off the different barrel and after 10 sec of rolling the remainder of bad oil out of the nozzle it fired right off. Really wish I would have checked all that first in hindsight.

From my previous experience with waste oil (had two at my last shop)  I have never seen it light period. It was really weird this lit with a torch even badly.

Next question is can the 250 gallons be saved somehow or do I call around to get it disposed of?

I need to clarify that it shut itself off without reaching temp. It was 56⁰and got up to 70⁰ in 30min. Thermostat was on 88⁰.
Carlin ign controller was blinking red. I assume it overheated from too much draft.

I did try adjusting the shutter settings but didn't notice a change in flame length. I already have them set around 2 a piece.

Does the +3000' motor have higher or lower pressure?
And the big question is would that prevent it from lighting by itself?

Flame is for sure more directional obviously. Still seems way too much as it hits the target and kind of splashes off if that makes sense. Still has some sparks in it as well.

Is diesel suggested to eliminate the fuel theory? I could try to run directly from a 5 gal can? The blower wheel is dirty colored but all the find are free and clear.

Ok all cleaned out. Let it try to light for 30sec and no go. Lit with torch instantly. Let burn for 37ish min. Smoke was med to faint haze and then cleaned up.

***Unit turned off on its own under thermostat temp.

 Assuming because my Airband/ shutter and draft aren't adjusted.

Haven't gotten a Guage yet to measure compressor pressure. Place local is closed for turkey day.

Is it safe to assume the reason it won't light itself is too much air pressure or bad fuel(even though once it lights it runs fine)?

Duh. Not sure why I didn't upload that. I assume this is the right picture.

Spark is healthy. Does not jump to anything else that I've seen in 3 cycles. Looks exactly like the video.

I was thinking that as well. You think I should worry about cleaning it and if yes do you have a good method? Brake cleaner, decreaser, soap? Brush ideas for getting in there. The tubes are 4in and 3 in respectively.

I'll upload the numbers on the pump. I tried finding the info on <3000 elevation pump and couldn't find much.

Still not convinced it's not user error on the black box. I never pushed it more than twice before I manually lit or cleaned it out but.....I'm not sure I've cleaned it super great. I've never really cleaned it better than pictured and assumed it was "good enough". Also am lost to how to get it better other than way more time.  Used a scraper and a windshield brush. I've tried iso alcohol as I have a bunch on hand.

Ok update time. Ordered the tune up kit. New nozzle, new electrodes, and new transformer from building owner. Cleaned the firebox out.

Will post pictures to show adjustments (by the book)  and ignition flame.

Is my ignition good?
How much burn off should I expect from the firebox at this level of clean?

I'll wait to put it back together and attempt to light after any responses.

I haven't been back yet. Wife's birthday weekend and I was waiting on the new nozzle. I won't leave you out of the situation.

By pump motors I assume you mean the oil pump?

I figured the new nozzle would be a decent first step as well. It gets here fri.

Pump looks original.... but that's a guess. I can pull numbers on it if there are any.

As far as I know it came from a local building that was sold at a local auction (should be set up for my alt). You know what assuming gets you though.

Yes adjusted correctly. I'm not happy about the parts but that's what the guy wants to do next. I'll take a picture or video of the ignition minus oil of course with the burner out.

The electrodes are adjusted by the book via micrometer. Verified spark at transformer and electrode tips. Verified that it is being blown into a torch like tip(blueish 3/4"out)

Oil is being heated for 15 minutes minimum and verified heater cartridges are making cases hot to touch. Haven't verified pressure due to no adjustment no access to gauge. Can confirm that line is bled and oil flows. Have confirmed a mist like fog inside fire chamber on ignition attempt. Confirmed nozzle is clear and clean.

Cannot confirm air settings but it DOES seem to be overfiring although it ran cleanish for around 4-5 min. Cannot confirm draft but have the damper set to allow most draft from the heater. Damper does not swing.

It looks like a bon-fire when it starts to huff and puff.

It also does throw sparks around from what it seems.

Like stated I don't have the luxury of letting it burn off and smoke out my shop. I do believe that you are correct that it's burning raw and causing the smoke. I'm assuming that chokes the stack until it's over with. I have to open it up and clean it out good tomorrow(fairly easy with the massive clean out door)

So relit this AM seemed better on those Airband settings from the start. After about 5 min it started the smoke backfire again so I shut it down and need am just going to clean it out good. I can't smoke out my shop as I currently work in it. I did take 3 videos and uploaded at the link shared.

I ordered a tune up kit because it still won't start on its own which doesn't make sense. I have everything for ignition and it touches of really fast with the torch. The tune up kit is a nozzle, cathodes, gaskets and etc. I also ordered a new transformer although I'm not convinced mine is bad. The very first time I fired it up it lit right away. Got a carbon bridge and wouldn't relight. Cleaned it off and still nothing. At this point I'm thinking it has to be the ignition.

 Oil is heating fine all the way to the gun. Shop has been above 55 all week and weekend.

There are 3 videos. Initial ignition, stack smoke initial, and video of raw fuel igniting and starting the shutter.

Also if you need me to upload pictures of anything I can do that.

Thank you again. One thing to note is that I can see the marks where the Airband and shutter WERE set at. (Almost 2 for both)

Would you advise setting to there assuming its closer knowing it came from a local auction?

If by smoking outside the stack you mean like operating normal but smoky? Yes. Then after I let it burn for around 5 min enough to burn off the raw(I think) and tried to adjust the flame to eliminate the smoke or get it to burn cleaner it started shuttering and puffing smoke out of the stack where it shouldn't be. The baro damper and chamber inspection port.
