Note. Gas consumption is calculated using a
caloric value of 38.7 MJ/m

) gross
or 34.9 MJ/m

To obtain the gas consumption at a different
caloric value:
a. For l/s - divide the gross heat input
(kW) by the gross C.V. of the gas (MJ/m
3
)
b. For ft
3
/h - divide the gross heat input (Btu/h)
by the gross C.V. of the gas (Btu/ft
3
)
c. For m
3
/h - multiply l/s by 36
