Oven – What temperature is the “warm” setting on a conventional oven

I would suggest the easiest way to cook ground beef with only disposable items is a grill. It's worked great for more than a couple of years.

But... If you don't have that, there are a few other things you can do.

Labor intensive but extremely effective is the raised rack made out of foil. You construct a tray out of tinfoil and add ridges to the bottom every inch to an inch and a half. This will cook your beef and allow grease runoff so you meat doesn't just cook in it's own fat.

The only other thing I could think of would be to cover one of your burners completely with tinfoil and use it like a frying pan, but i'm prertty sure that's gonna result in a lot of cleaning time, so it would probably be a negative once you took it all together.

You can do a low temperature cook on your ribs the same way you would do your pork shoulders. It's just the cooking times are shorter, that's all.

Set your oven to 250-275F, and roast those ribs until they're done. I've had beef ribs done in as few as 3-4 hours, but as many as 5. Optionally, you can foil your ribs about halfway into your cook, with some liquid in the foil pack. Just be aware that they'll cook faster if they're foiled. And depending on your preference, you may want to take them out of the foil to finish them.
