A customer purchased a burner from me, and now he wishes to return it. He doesn't claim that it doesn't work, or that he's simply having buyers remorse, or even that he just doesn't want it anymore, but that it doesn't produce as many BTU as claimed. He goes so far as to claim that he's tested the BTU output of the burner. I really don't have any problem giving a refund if the item is returned, but his accusation that the BTU output is inaccurate is upsetting. I used the BTU calculator from Ron Reil's page to determine the output, and several have agreed that it's accurate, .042" orifice at 20 PSI yields ~104K BTU. We used a relatively conservative 0.75 for the discharge coefficient.
So, here's my question, is there a device that could measure the BTU in a forge, or is he likely just making it up? I just can't see directly measuring the BTU output without capturing all the heat lost from the forge, which would measure the forge's efficiency and not the burner itself.
I fully expect that eBay will force me to allow him to return it, but I want to make sure my BTU calculations aren't that far off.

"Sorry there was a Miss type im only getting 87655 out of this burner .I have thermo testers and others way of figuring out how hot something get it not rocket science so I'm telling you this isn't putting out 100000 BTUs not my first burner I build forges for a living so I'm not a amateur"
