ECLIPSE WGD
THROUGHPORT GAS BURNER
Luminous Flame Ensures High Heat
Transfer and Low NOx
Water cooled throughport
burners for regenerative
glass furnaces
Eclipse WGD burners are
compact water cooled burners
designed to be inserted into
the port neck of a regenerative
glass furnace. The burner is
fitted to the Eclipse retraction
mechanism to withdraw the
burner from the furnace when
not firing. Using through port
burners with the retraction
mechanism ensures the lowest
possible maintenance and
therefore consistent combustion
essential for high glass quality.
The burner produces a flat,
fan shaped luminous flame
using a unique arrangement
of converging flat jet nozzles.
Only one burner is to be used
in each port. Excellent flame
coverage of the glass is ensured
with this type of burner and
flames are extremely luminous
ensuring high heat transfer and
low NOx. The flame location
is very easily adjusted within
the furnace ensuring that
combustion is taking place
at the optimum position.
