: : I retrofitted my boiler to run on Natural gas. How do I calculate the steam output (in kg/hr) from the natural gas consumption (in Nm3/hr).

: : FYI. I do not have a steam flow meter installed in my steam line.

: Use the following formula:

: Daily volume in cu. ft. x heating value in fuel (usually 1,025 btu/cf for natural gas)/Enthalpy in the steam (from steam tables)/factor of evaporation

: factor of evaporation = enthalpy - (feedwater temp -32)/970.3
