Burn time for Coleman 500A?

Post by Cajuncook1 »

Anyone with knowledge of the burn time of Coleman 500A? Want to do some outdoor cooking in Oct/Nov/Dec.

Thanks guys for any information.

Cheers

I use mine one or two times a week. It seems pretty good on fuel. But I think it's a question that would be hard to answer due to how far you have the fuel valve opened. They go from a nice simmer to a real roar and everything in between.

I'd suggest you take it out and try it out now so you can see for yourself how it works under your expected conditions. Just use water in it instead of food.

It won't burn for three months, I reckon. :)

I've run mine flat-out for three hours, but I can't say how much longer it would have gone. I do know that I fill my 500 and 500A infrequently when using them for cooking, which is rarely if ever flat-out.

Thanks, for the information 😎

Planning on cooking some gumbo, stews, and chili.

I like to slowly cook the beef and pork stews. The meat just falls apart in you mouth.

I think I can help out here, but we're going to have to do MATH. :shock: :mrgreen:

Ok, so 1 gal CF = 117,000 BTU. That comes to ~914 BTU/oz. The 500a holds 2 pints of fuel (32oz) so that's 32 * 914 = 29,250 BTU in the tank. The burner is referenced in multiple places as a 7,500 BTU/hr stove. 29,250 BTU / 7,500 BTU/hr = 3.9 hours at full tilt until the tank is dry. Obviously, you'll get more runtime out of it if you throttle back, but you shouldn't get much less than 3.9 hrs from a full fill, assuming that the tank can be completely sucked dry.

Now, factor in elevation, wind speed and pot geometry . . .. I tried to make coffee on my 500A in a breeze. I had a homemade, built-in windscreen (a very fine one, if I do say so myself), and I finally gave up on coffee. I later bought one of the stand alone windscreens, but haven't yet got around to trying it with the 500A.

Those factors won't change the runtime. None of those factors changes the BTU rating of the fuel, nor the BTU/hr input to the burner. Remember, BTU/hr ratings are input and not output. That's why we can take the BTU value of the fuel and use the BTU/hr of the burner figure a runtime. It will ABSOLUTELY impact the ability to transfer the heat to the things you want to heat up, but the runtime will be the same. I agree, the 500a is really adversely impacted by wind.

Thank you Michael 😊. Appreciate your thoughts and details.

So that Coleman 500A , if running properly and with a good windscreen, could give some good lengthy burn times. This would definitely help by not having to stop, cool and refill during the cooking.

😎😎😎😊😊😊

Thanks guys!

The big thing is the windscreen. Gotta have a windscreen on a 500, 500A. I made mine from a stainless steel pot that I got at Goodwill. I wonder if Timm's windscreen plans survived the move?

So true! I'd forgotten, as mine have screens.

Just in case:

Master Wysong would kick my ass up the block and back if he saw those plans!

I did a test with my 500A and they about halved the boiling time for a quart of water in a calm shop--makes even more difference in a breeze.

For cooking outside in a breeze, more windscreen is needed for best efficiency:

I was just camping a few weeks ago and was using my 500A with a Kamp-Site heat drum and a Paulin propane heater as I was unsure of fire restrictions. I was running the 500A at full blast and I think a tank lasted about 3 hours. Should last a long time at a low flame for a stew. I would also use a diffuser. I got inspired by Timm's wind screen and made one out of brass. Another wind screen might be good too.

If you can switch to another burner/stove for that time, you can just keep trucking while you cool/refuel.

I honestly can't guess how long any of my stoves will go on a tank. they re on/off, wait for the next meal, etc, repeat as needed so :cf_idontknow:

Timm's all nickle plated 500 is the teats! Here is my screen drawing... might need slight adjustments.
Drilling holes in the brass was challenging. I also made a heat deflector for the fuel knob (1st pic).

For drilling holes in thin material I use a step drill bit, much less painful than using a twist drill bit.

Drill press is perfect for drilling in metal. Clamped down, slow speed, variable constant pressure.

I use 500’s while out camping. One with a windscreen and one without. The one with was way hotter. It funneled the heat up to a griddle. One side was bacon the other was eggs so it works out well.

Hey David, I thought you might find this interesting too. I made a case for my Coleman oven and also a stand to use it with a 500 stove. I used rivet nuts and threaded rods for the stand. It will reach pizza temps of 425 degees.

By sleebus math 3.9hrs on a full tank. I was saying 3 hours full blast on a full tank, but just a guess.
Gar

Here is a boil test I did a while ago (bored I guess):
Stove Boiling Test
1/2 Qt. cold water in a Revere Ware 1 Qt stainless pot, no lid. Alt: 5,280 ft.
Main burner on 2 and 3 burner stoves.

Stove / Model Fuel Burners BTU Time
Coleman 500A: CF 1 Cast/BaB 7500 3:05.9 min.
Coleman 502: CF 1 Band a Blu 4500 4:31.6 min.
Coleman 426A: CF 3 Band a Blu 25,800 2:19.4 min. (7900, 10.000, 7900 BTU?)
Coleman 3H: CF 2 Cast Iron 10,000 est. 2:23.7 min.
Coleman 5410A: Prop 2 Band a Blu 10,000 2:22 min. (1:22.8 min. faster than Optimus 831)
Optimus 831: Prop 2 Optimus NA 3:44.8 min.
Optimus 99: CF 1 Optimus NA 4:09.4 min.

Things to remember: Coleman was optimistic about both outputs and fuel capacities. I measure my fuel when filling/refilling and come up with a few ounces short of what Coleman claims.

I fill to the bottom of the fuel bug, then measure that. Here's what I have for the little guys (suitcases take a larger measuring cup):

Image

500/500A fount is the same capacity as the 220/228. 28 oz vs. 32. Fill too high and you'll be pumping a lot for the first half-hour--or just spilling fuel.

I don't have a way to measure output, but I'm sure the marketing guys over stated that, too.

Note that the lowest mark on my cup is for the 502 stove. I just ran one for heat with a heat drum. 3 hours 21 minutes to empty, full open.

Well, you could always get the stove running, weigh it, wait 15 mins, weigh again. Using the BTU content of the fuel and its weight, you can calculate the BTU used. Multiply that x4 (since it was only a 15 min test) and you'll get BTU/hr.

How about 3:21 from 16 fl oz for the 502?

Ah! Ok, this I can work with.

So, that's 201 mins of runtime, using 16 oz fuel. You're burning 0.0796oz/min. In 60 mins, you'll have burned 4.776oz. Fuel is 914.06 BTU/oz, so 4.776 x 914.06 = 4,366 BTU/hr. Pretty darn close to the claimed 4,500 BTU/hr. :shock:

Remember, my measurements are in fluid ounces, not weight. Might have to convert that to actual ozs--which will depend on temperature, too. I'll toss 16 fl oz into the cup and weigh it today (gotta refill anyway).
