17/07/2017 · Adjust for the burner efficiency by dividing consumption at 100 percent efficiency by the burner efficiency rating. For a burner that is 95-percent efficient, divide by 0.95. In the example: 40,000 BTU divided by 1,075 = 37.21. Adjusting for burner efficiency: 37.21 divided by 0.95 = 39.17 cubic feet of natural gas consumed in one hour.

Once through boilers: in once-through boilers the pressure loss of the evaporator is between 5 and 30 %. Forced and natural circulation boilers: the pressure drop in the evaporator part of drum-based boilers does not affect the pressure loss of the main steam/water flow through the boiler.
