Auto ignition Propane Asphalt heater

[@mopclabs]

Excellent burner

Seems powerful 🔥🔥

You actually made something very similar to what is used on an incinerator/retort/cremation machine. If you have issues with the sparkplug, you can very easily change it out for an incinerator "igniton rod" or "flame rod (can be cut to length) ". Both look very similar to a sparkplug. Do a Google image search and you will see what I'm talking about.

Are you talking about the spark type with the long electrode ? Great comment . If your referring to the silicon nitride ive had to many failures do to there delicate positioning needs . The Long electrode flame rods look like a great idea though . Ive bin looking for a good resistor free alternative . I am using a NON - Resister spark plug . Thankyou for pointing this out great advice

I used to work on tar trucks and they need a lot of heat as they have to heat up anywhere from a couple hundred gallons to several thousand gallons of asphalt tar. The way they work to heat the tar is the burner heats a tube that runs to the front of the tank and then loops back to the back on the opposite side of the burner. It makes a big U in the tank. With the igniter try using a flame eye or a flame sensor so it turns the igniter off when a flame is detected. That is how the ones on the tar trucks are used as well as the ones at the asphalt plants. I hope this helps you out in what you are going for.

I would replace the spark plug with a hot surface igniter that’s designed for a furnace.

2 problems with that notion my friend They are to unreliable , ive had them brake way to often . They can handle a gentle heating from a furnace flame but in my experience they break and stop working . I have 3 video where we try those and they work for the test but they die way to easily if not perfectly positioned . Secondly a delay circuit is needed to give the heater a couple seconds to heat up , though doable its not economically viable to add the circuit . We are looking at $45 Vs $65 . Doesn't seem like much but a Geya time relay is $29 before tax and the unreliable silicon nitride ignitor is also $29 { silicon carbide is worse for reliability } . The customer was down to his last dollar at 490 bucks for this rig and yes $20 more for a less reliable set up can be a show stopper . And all this for a system that may fail if not properly installed . I had a customer burn one up and was not happy so i have since stepped away from them . If you dont use the time relay an explosion will likely result in the heat tube this fires into . I had high hopes for the silicon nitride ignitors but after taking a loss on the unhappy customer it keeps me up at night LOL . It sucks because they are great at lighting waste oil nd diesel even better than a spark but the reliability takes some serious time experimenting for flawless implementation . Not bashing your idea its just from my experience with them I fell out of love with them when i had to buy a second one to replace the one that cracked . there is a poor soul out there right now who is not happy with me over the silicon nitride ... I had to keep this unit under $500

I tried one without a timer relay one time and sure enough me and the guy both forgot to turn it off after the unit fired up and toasted it . I have the videos on those untis but im 1,100 videos deep and its to much hay for me to look through at the moment i know one of the videos was a diesel jet burner if you care to look for it

[@NOBOX7]

With the perfect position determined after days of testing yes it would work with a timer circuit , however.....

Would a battery powered grill starter work? I have one from an old gas grill that runs on 3 AA batteries and has 4 wires that will jump a 3/8" spark on each.

[@NOBOX7]

Yes it would as some have a switch option . it would take about 25$ of the price . I have one on hand but wanted something a bit more industrial

[@ProlificInvention]

I was thinking 5 volt 2 amp USB charger hooked by a wire to the power, switch set to on all the time, that way you could just turn power on and off all the time. Then 4 spark plugs with large gaps could be used
