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
