four-passFin SystemINSPECTION ACCESS■ The waterside openings arelocated in the most effectivepositions. The lower handholesoffer far better access for bothcleanout and inspection.■ These more functional locationsavoid the obstructing handhole“tunnels” used by ourcompetitors.■ The top opening offers a strategicview of the furnace crown sheet.MORE STEAM STORAGE■ Capacity to handle swing andspike loads – quick recovery -quick response.■ The larger steam-release surfaceis calmer, reducing carry over ofunevaporated water.■ The resulting drier steam alsoreduces system scaling.■ In addition, dry steam helps toeliminate unnecessary extracondensate. Energy and fuelare saved. Longer life results.FOUR-PASS DESIGN■ The gases leaving the furnaceare split four ways and travelthrough four individual serpentinefin passages to the stack outlet.■ Each quarter of the heattravels its own four-pass path(see illustration below).■ Heat transfers evenly to the finsand boiler shell, eliminating themetal stress due to uneven heattransfer common in other designs.This illustration showsthe progression of fourgas paths around thecircumference of the boiler shell.1. Primary-pass in furnace pipe.2. Second-pass follows paththrough fins along outsideof shell.3. Third-pass follows path throughfins along outside of shell.4. Fourth-pass follows paththrough fins along outsideof shell, then merges togetherto exit exhaust stack.OPTIONS AND ALTERNATIVES■ We specialize in customizing yourboiler. The Cyclone can beequipped to suit a wide variety ofinstallations and specifications.We will help direct you to the mostcost-effective models and features.SIMPLE INSTALLATION■ Unit is skid mounted for easyhandling.■ Factory wired with wiring schematicincluded in the manual.■ Efficient and space saving layout.AVAILABLE ACCESSORIES■ The Cyclone is available in acomplete package with anoptional compact boiler-mountedfeedwater system for a finishedwired and piped, ready-to-fire unit.■ Blowdown separators are alsoavailable.

Four-PassCycloPower Fire4VT Cyclone SeriesFOUR-PASS ■ SPACE SAVING ■ TUBELESSTURBULENT FLAME■ Heat is forced down, with thefire whirling and spinning againstits natural flow. This patternenhances recirculation, mixingand heat transfer, driving moreenergy into the water for greaterfuel-to-steam efficiency.RELIABILITY■ The furnace crown is watercooled, eliminating troublesomerefractory breakdown inherent inunits of inferior design.■ No fire tubes, water coils or“in the fire” mud rings to burnout.“EYE HIGH” BURNER■ No step ladder is needed toservice.■ No bending over or sitting on thefloor.■ The air intake is located in thecenter of the unit so dust is notpulled from the floor.DURABILITY■ Fire does not pass under thebottom mud ring, eliminating theblistering that occurs with otherdesigns.■ Cooler furnace gases are locatedat the bottom of the vessel wherescale is most likely to occur.Baking of scale is alleviated.EASIER SERVICE■ Fireside fin access in top andbottom.■ Access opening above feedwaterinlet for easy cleaning.■ Thoughtfully engineered with theowner in mind.■ No heavy doors or covers tocomplicate service procedures.SAFETY■ Electrical components are locatedaway from the floor, helpingeliminate the possibility of watercoming in contact with electricity.■ Boiler built to ASME Section 1,High Pressure Boiler Code.■ CSD-1 approved.■ Burner/Boiler UL Packaged.
