PROCEDURE TO REFER BURNER OPERATING CONDITION IN HIGH ALTITUDE PLANTS

Find the 

corrected burner capacity

 for the plant’s altitude in

chart

 1

 and the 

corrected pressure

 in chart

 2

.

Check in the firing rate graph of the burner (page 5), if the work-
ing point defined by the values above is within the range limits.

If not, higher burner size is needed.

Note

Charts are based only on altitude variation (reference tempera-
ture = 68°F , 20°C)

To get the combined correction in case of different air tempera-
ture, a compensation of 

1000 ft each 20°F (305 m each 11°C)

is applicable.

Example

Rated capacity = 6000 MBtu/hr - Rated air pressure = 1.5”w.c.

Real altitude = 5000 ft - Real temperature = 108°F

 = 108°F - 68°F (reference temp.) = 40°F (equivalent 2000 ft

variation)

Proceeding as descripted above and considering a “virtual alti-
tude” of (5000 + 2000) ft 

- the corrected capacity is 7694 MBtu/hr

- the corrected burner air pressure is 1.92

Reference conditions (Charts 1-2): 

– Ambient temperature 68 °F (20 °C)
– Barometric pressure 394” wc (1000 mbar)
– Altitude 328 ft a.s.l. (100 m a.s.l.).
