Fuel Type
Table 3.1 Fuel Type
If using an alternative fuel supply, contact Eclipse with an
accurate breakdown of the fuel components.
Fuel Supply
Select the turndown required.
The high turndown option includes a ratio regulator with
bypass adjustment for lower inputs.
Combustor Type & Material
Select a combustor type based on the application. Low
temperature applications use an alloy combustion tube.
High temperature applications use a silicon carbide (SiC)
tube or a refractory block & holder. See datasheet series
110 for specific temperature ratings. For vertical down-
firing applications with block and holder, consult factory.
Combustor Length
Select a combustor length. Optional lengths are available
on some models. Nozzle position will vary with combustor
length. The nozzle position determines the location of
heat release.
Figure 3.2. Combustor Length
Nozzle Type
Select the high temperature nozzle option if chamber
temperatures are expected to exceed 800°F (425°C).
Air Supply
The RatioMatic burner can be ordered with a combustion
air blower supplied and mounted directly to the burner
body or depending on burner size with a threaded, or
welded inlet to accommodate a remote blower. The
remote blower must provide adequate pressure and flow
per the appropriate datasheet series 110.
Control Motor
Select a control motor. Eclipse Trilogy T500 actuators are
standard on all Eclipse packaged burners, other control
motor options are available which Eclipse will mount to the
burner. RatioMatic burners can be ordered with control
motor bracket and mounting hardware only. Customer
supplied control motors must conform to these
specifications:
• rotation not to exceed 2 rpm
• minimum torque of 25 in-lb (2,8 Nm)
