1.7.1Volumetric Method to Verify the High Flame Setting, Mathematical

WARNING! No other gas equipment can be in operation during this procedure. Calculation of flow rate E in ft3/hour

E =

FP

 

Hi

E = Flow rate in ft3/minute

FP = High Flame Power setting in BTU/hr

Hi= Heating value in BTU/ft3

Thus, for natural gas:

E = 60,000

BTU/hr

=

57.75 ft3/hr

=

0.96 ft3/min.

1040

BTU/ft3

 

 

 

 

E = 0.96 ft3/min.

Calculation of the natural gas needed in 1 hour by a 45WDG (3 burners) at full power:

57.75 * 3 = 173.25 ft3/hr =

2.89 ft3/min.

The time and the flow measurements should be taken at the gas (flow) meter with a chronometer (stop watch).

To run the test, open the manual gas cock valve, start up the unit according to the start-up instructions on page 24 and set the manifold valves to the high flame setting ("on" position).

Allow the unit to pre-heat (burn) for 10 to 15 minutes. Verify that the flow rate is calibrated to the appropriate flow rate indicated in the table.
