: I need some help in calculating the mmbtu rating of a steam boiler. Is there a formula for this? what knowns are used for the calculation
First thing are you looking for an input or output? The output is easy, it takes ballpark 1,000 btu to turn 1 pound of water at 212 deg F into 1 pound of saturated steam. So if your steam output is 1,000 lbs/hr that is roughly 1 mmbtu output.
Input is different because that is a function of the efficiency of the boiler. That will require more detail on your boiler
