How to Calculate Gas Consumption in a Gas Boiler Burner?

A natural gas burner rated at 40000 BTUs per hour divided by 1000 BTUs per cubic foot uses approximately 40 cubic feet of natural gas in one hour. Exact Gas Consumption Step 1 Multiply the burner efficiency by the energy content of the gas being used. Natural gas contains 1075 BTUs per cubic foot; propane contains 2570 BTUs per cubic foot. Step 2

How to calculate the start-up cost of a natural gas boiler ...

Jan 09 2017 · In that case your are basically looking for an efficiency calculation. Since this will vary greatly by boiler design and quality you will need to measure it empirically. Kw of heat out/ Kw of gas input = efficiency. Lets say you calculate it at 1 minute and 5 minutes from start. For 0 to 1 minute you multiply 1 minute x (1 - efficency) x gas flow.
