Eclipse RatioMatic Burner, RM Series, V5, Design Guide 110, 11/11/2011
• 90° stroke
• continuous modulating or high/low modulating
control
• reversible direction of rotation
certain applications may require control motors with
a limit switch or switches if:
-
the burner capacity is to be limited to fit an
application
- the chamber is to be fired with positive or
negative pressure
- the chamber pressure is outside the range
-1" w.c. to +1" w.c. (-2,5 to 2,5 mbar)
- there is a need to indicate a high and/or low
fire air butterfly valve position
Limit Switch
Limit switches monitor the position of the integral air
butterfly valve. Select high, low, high and low, or no limit
switch option. Proper selection is based on preference,
control system, and local code.
Loading Line Type
All RatioMatic burners have the option of plastic, flexible
braided stainless steel or rigid stainless tube loading line.
Selection depends on application and environment.
Piping Connection
Select the gas pipe connection including the pipe thread
type and the turndown required.
The piping, burner gas inlet, and ratio regulator are
threaded using the customer selected pipe thread option.
The high turndown option includes a ratio regulator with
an adjustment for lower inputs.
Flame Supervision
Determine if a flame rod or an ultraviolet (UV) scanner will
be required. Flame rods are available on models RM0050
through RM0700, burners with alloy or SiC tubes. All other
options and models require UV scanners. If a UV scanner
is required, it must be ordered separately.
NOTE: Some flame monitoring devices do not work with
alternative fuels. Consult Eclipse for assistance when
selecting flame monitoring equipment for alternative fuels.
See Step 5 for additional information on flame supervision
selection.
A UV scanner could possibly detect another
burner’s flame if it is in the line of sight, and falsely
indicate flame presence.
Step 2: Blower Option Selection
Standard blower options are listed in datasheet series
110, additional blower options are available through
Eclipse. Price and leadtime may vary.
Power Supply Frequency
Select the 50Hz or 60Hz option. The 50Hz blower motors
have IEC frames and are CE marked. The 60Hz motors
have NEMA frames.
Pressure & Flow
Eclipse offers SMJ blowers for remote blower
applications. The RatioMatic burner can be ordered with a
combustion air blower supplied and mounted directly to
the burner body or with a threaded, flanged, or welded
inlet to accommodate a remote blower. Remote blower
must provide adequate pressure and flow per the
appropriate datasheet series 110.
Blower Motor Type
Motor types include various options: voltages, single or
three phase, TEFC or automotive duty enclosures.
Blower Inlet
When selecting an inlet, consider the following:
• amount and size of particles in the air
• sound level requirements
• space limitations
• cleanliness requirements of the process
Motor Orientation
Right-hand blower motor orientation is standard. If left-
hand blower motor orientation is required, contact factory.
