Tube Shrouding Considerations
In applications where process air may flow perpendicular
over the combustor, a metal shroud should be installed
around the combustor that is 20% larger than the
combustor diameter with a length that covers the
combustor slots by 100 mm (4"). Slot dimensions can be
found in Winnox datasheet, series 111.
Chamber Wall
Make sure the chamber wall
support the weight of the burner
the mounting area. See Figure 3.3.
NOTE: The slots in the combustor must not be covered
with insulation. If necessary, taper the chamber insulation
at a minimum of 45° to provide clearance for the
combustor slots. Slot dimensions can be found in the
Winnox datasheet, series 111.

Burner Mounting
Mount the burner to the chamber wall using eight (8)
customer supplied nuts and lock washers.
Alloy Combustion Tube
1. Be sure gasket is installed between burner
chamber wall . See Figure 3.4.
2. Pack fiber insulation around the tube to a depth not
beyond the combustor slot position, as shown in
Figure 3.4.
Placing insulation over combustor slots will
impede burner
combustor life.

Refractory Plug
When using the refractory plug the customer must provide
a refractory combustion tube. The customer is responsible
for supplying all refractory materials for combustion tube
field installation as follows:
1. Install the chosen refractory realizing it is essential that:
• The combustion tube dimensions are held as given
in the Winnox Datasheet series 111. See Figure 3.5.
• The inside diameter of the combustion tube is
concentric with the refractory plug.
2. Support refractory combustion tube according to the
refractory supplier's recommendations. The alloy
anchors should be coated with bitumastic whenever
they are used.
3. Fiber insulation must be installed between the
refractory plug and customer supplied refractory
combustion tube.
4. After the burner and refractory have been installed, a
proper curing schedule should be followed according
to refractory supplier's recommendations.
