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 6), if the working point defined by the values above is within the range limits. 
If not, higher burner size is needed.

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.)

Note

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

To get the combined correction in case of different
air temperature, a compensation of 

1000 ft each

20°F (305 m each 11°C) 

is applicable.

Example

Rated capacity = 3000 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 altitude” of (5000 + 2000) ft: 
- the corrected capacity is 3847 MBtu/hr;
- the corrected burner air pressure is 1.92.

Burner RS 120/M LN is OK
