Eclipse Winnox WX Series v1 Design Guide No. 111, 9/25/2008
Step 1 describes how to select burner options to suit an
application. Use the Winnox Price List and Datasheets No. 111
when following this selection process.
Caution:
Consult EFE-825 Eclipse Engineering Guide, or contact
Eclipse if you have special conditions or questions.
Burner Model / Size Selection
Consider the following when selecting the burner size:
Heat Input: • Calculate the required heat input to achieve
the required heat balance. The burner air supply option
selected will affect available heat output from the burner.
Power Supply Frequency: • Burner capacity will vary with
power supply frequency (50Hz or 60 Hz power).
Combustion Chamber Pressure: • Consider the effects
that large or varying chamber pressures have on burner
performance.
Altitude:• The maximum burner capacity is reduced by
approximately 3% each 1000 feet (300 meters) above sea
level.
Combustion Air Supply:• Combustion air should be fresh
(20.9% O
2
) and clean (without particles or corrosives).
Combustion Air Temperature: • Changes in air supply
temperature can affect the burner capacity. The
combustion air supply temperature should not exceed
250°F.
Fuel Type: • Variation in caloric value and density will
affect burner performance. Nominal burner performance is
based on fuel properties in Table 3.1.

Air Supply
Select either a combustion air blower mounted directly to the burner
body, or a pipe connection type for remote blower operation. For
each selection, the burner will include an integral air buttery valve
(BV).
