Note:
For pilot configurations using the tee fitting option to
connect the pilot fuel supply ahead of the 325 series
bypass regulator, back pressure to the bypass regulator
must be within an acceptable limit. The bypass regulators
used on all Winnox burners are designed to operate at
outlet pressures up to 2 psig with inlet pressures up to 10
psig. Back load pressures (outlet pressures) of 2 psig with
no inlet pressure will not affect components or the normal
operation of the regulator.
Warning:
Do not operate Winnox burners with gas inlet
pressure less than the minimum listed on the Winnox
datasheet. Lower gas inlet pressures may cause the
ratio regulator to remain fully open at lower inputs
as the burner transitions from low to high fire. This
could result in the possible accumulation of unburned
fuel in the burner which, in extreme situations, could
cause a fire or an explosion.
Firing Chamber Dimensions
The Winnox is a low emissions burner that might require a larger
firing chamber than a standard burner.
Chamber dimensions are a function of chamber temperature,
process air volume and burner input. Contact your Eclipse
representative to review your chamber design.
