How long does one can burn?

Sterno rates each can at about 6 hours. Real-world time depends on wick height and drafts; a taller flame burns faster.

Can I reuse a partly burned can?

Yes. The twist cap lets you snuff the flame and relight the same can later, though a can left on its side may have a soggy wick.

No. It is a warming fuel for chafing dishes and warmers, not a cooking flame for direct grilling or boiling.
