Assuming you start at 142°F Not intended to be smartass just to show how super awesome Google calculation is. This calculation neglects convective and radiative heat loss away from the boil kettle and assumes perfect heat transfer from the burner to the boil kettle. My burner is 55,000 BTU and brings 6.5 gallons to a boil from mash temps in around 15 minutes.

I just seen some deals on 10,000 BTU two burners so that will not work
My grill side burner gets it to 190 after a 30 min. Grr thank you for your help

I bought this unit a month or so ago, cost was $79 with mail in rebate from Gander Mountain outdoors store. It has two 30,000btu burners and holds 2 15 gallon keggles nicely. They also sell one a little bigger that has two 40,000btu burners on it. Mine does a decent job if you are not in a big hurry, it put me into AG brewing on a budget and does not take up lots of storage space .
It is a Camp Chef Explorer-2 camp stove

185,000 BTU for $49 shipped and 234 4.4 star reviews most of them from fellow homebrewers.

I bought the SP10 a few years ago, my brewing buddy took it off my hands in a swap and he still uses it. We did 12 gallon batches and it totally kicked ass, from mash temps to boiling in probably 20-25 minutes. He now has it hooked up to his natural gas line in his garage.

How did your buddy convert this to use with natural gas?
