Dear Ivan,
This information should be provided by the manufacturer but, for a rough value, you can multiply the volumetric flow rate (that it should be convert into Nm3/h(standard conditions)) by the lower heat power (LHP). An average value of the LHP of the natural gas is 9065 kcal/Nm3.
Regards,
Alberto
