Definitely. I have 3 burners on my stand that are all run off a single propane tank. It's rare to have all 3 going at once, but I frequently have 2 running - either heating strike and sparge water at the same time, or heating water for second batch sparge while starting the boil with first runnings.
You'll want to have a valve for each burner so you can regulate their flame independently, or shut one down completely.
