INSPECTION
ACCESS
- The waterside
openings are located in the most effective positions. The lower handholes
offer far better access for both cleanout and inspection.
- These more functional
locations avoid the obstructing handhole “tunnels” used
by our competitors.
- The top opening
offers a strategic view of the furnace crown sheet.
|
MORE
STEAM STORAGE
- Capacity to handle
swing and spike loads - quick recovery - quick response.
- The larger steam-release
surface is calmer, reducing carry over of unevaporated water.
- The resulting
drier steam also reduces system scaling.
- In addition, dry
steam helps to eliminate unnecessary extra condensate. Energy and
fuel are saved. Longer life results.
|
FOUR-PASS
DESIGN
- The gases leaving
the furnace are split four ways and travel through four individual
serpentine fin passages to the stack outlet.
- Each quarter of
the heat
travels its own four-pass path (see illustration below).
- Heat transfers
evenly to the fins and boiler shell, eliminating the metal stress
due to uneven heat transfer common in other designs.
|
|
This illustration
shows the progression of four gas paths around the circumference of
the boiler shell.
- Primary-pass in
furnace pipe.
- Second-pass follows
path through fins along outside of shell.
- Third-pass follows
path through fins along outside of shell.
- Fourth-pass follows
path through fins along outside of shell, then merges together to
exit exhaust stack.

OPTIONS
AND ALTERNATIVES
- We specialize
in customizing your boiler. The Cyclone can be equipped to suit a
wide variety of installations and specifications. We will help direct
you to the most cost-effective models and features.
|
SIMPLE
INSTALLATION
- Unit is skid mounted
for easy handling.
- Factory wired
with wiring schematic included in the manual.
- Efficient and
space saving layout.
|
AVAILABLE
ACCESSORIES
- The Cyclone is
available in a complete package with an optional compact boiler-mounted
feedwater system for a finished wired and piped, ready-to-fire
unit.
- Blowdown separators are
also available.
|
|
TURBULENT
FLAME
- Heat is forced
down, with the fire whirling and spinning against its natural flow.
This pattern enhances recirculation, mixing and heat transfer, driving
more energy into the water for greater fuel-to-steam efficiency.
|
RELIABILITY
- The furnace crown
is water cooled, eliminating troublesome refractory breakdown inherent
in units of inferior design.
- No fire tubes,
water coils or “in the fire” mud rings to burn out.
|
“EYE
HIGH” BURNER
- No step ladder
is needed to service.
- No bending over
or sitting on the floor.
- The air intake
is located in the center of the unit so dust is not pulled from the
floor.
|
|
DURABILITY
- Fire does not
pass under the bottom mud ring, eliminating the blistering that occurs
with other designs.
- Cooler furnace
gases are located at the bottom of the vessel where scale is most
likely to occur. Baking of scale is alleviated.
|
EASIER
SERVICE
- Fireside fin access
in top and bottom.
- Access opening
above feedwater inlet for easy cleaning.
- Thoughtfully engineered
with the owner in mind.
- No heavy doors
or covers to complicate service procedures.
|
SAFETY
- Electrical components
are located away from the floor, helping eliminate the possibility
of water coming in contact with electricity.
- Boiler built to
ASME Section 1, High Pressure Boiler Code.
- CSD-1 approved.
- Burner/Boiler
UL Packaged.
