Multiple burner ignition schemes.
Multiple burner ignition schemes.
(OP)
I have a case where four burners, (100-150kBTU), need to be ignited at the same time. They're all mounted in a square pattern about 20 inches to a side.
They will be automatically cycled. The configuration contemplated is a pilot tube running around the entire perimeter. The customary thermopile monitoring the end of the pilot tube. At first glance I'm not comfortable with this method as I've seen areas of pilot-tube-like burners go out for various reasons. This of course would mean a burner going on for a while unlit. (bang) Heck, it could mean three of the four burners going on for a while unlit!
Is this a typical solution or is something else more commonly used now?
I was looking at individual electric ignition detection systems and considering using one per burner but this gets kinda pricey at about $200 per burner.

Please give a little more description of your gadget. In your OP I didn't get a picture of diagonal corner burners. Maybe it is just the old boiler guy in me but I envisioned 4 burners on one wall in a square pattern.

All burners point straight up.

I think the pilotless ignition should be cheaper than what you've cited, particularly in quantity: http://w
Worst comes to worse, you could get a standard, 4-cylinder electronic car ignition retrofit kit, or build one yourself. Worst case scenario is 4 ignition coils with 4 12-V drivers.

RE: Multiple burner ignition schemes.
you say the burners will be automatically cycled, will a pilots heat be lost, if not, then a pilot is much safer than auto ignition of the entire buner, it would still be best to ignite a pilot, which in turn ignites the burners once a flame is detected.

IRstuff; That's an inexpensive novel idea to cannibalize a stove top. A concern would be the ignition system for 9kBTU burners not supporting 100kBTU burners for some reason. ??
Just so I'm clear on this your suggestion is like a continuous spark that just shows up next to a valved-on burner. Testing during setup that the burner always lights?
dcasto; You're suggesting something like:

Which proves a pilot light is positively on and assumes that if the pilot light is on, then the burner shall ignite.
If these burners are all pointed into a kiln that's >>1000F would not any gas ignite automatically? Of course since they have to initially ignite with a cold kiln... I guess that's a moot point.

Can't think of any reason why an even larger burner would have problems, unless it's air flow and mixing.
Actually, my only problem has been that the gas doesn't turn on like it's supposed, and takes up to about 20 seconds, but that's all mechanical, so it's likely to bew sticky valves somewhere.

I assume these are power burners???
