Packaged Marine DesignThermal Fluid (Hot Oil)HeatersFor Heating Asphalt Barges, Tankers, And Any Other Application RequiringDependable Heating
13 Models Starting At 500,000 BTU/HRTopping Out At 20,000,000 BTU/HRVolcanic Heaters are available with single or double wound helical coils pendingrequirements
Volcanic Heater, Inc.
Volcanic marine typethermal fluid heatersoperate within a closed loopThe end mounted burner firesdown the inside of the helicalcoil unit, heating the thermalfluid, which is pumpedthrough the coils and travelsthroughout the system backto the expansion tank. These2 pass gas flow systems operate with precise temper-ature control, and can reachtemperatures up to 399o withclass II barge piping or higherwith class I barge piping whileoperating at minimal low pressure.
Heat transfer takes place byconvection and radiation onthe inside of the coil surface --convection on the outside.
The Volcanic heater, using itsoriginal Hopkins design is along proven rugged workhorse suited for on-deck usage.
Volcanic marine heatersare complete packagedheaters with these great features� Low maintenance.
� Unattended operation.
� Automatic running and safety controls.
� No rust, no corrosion, no freezing with hot oil systems.
� Built to customer specs.Control panel and expan-sion tank can be mounted in "right hand or left hand" position.
� No pressures associated with a thermal fluid closedloop system.
� Volcanic heaters come witha one year warranty.
Several Volcanic Heaters can beseen "on-deck", heating asphaltcargo on this inland waterwaysbarge
The burner and control panel are protected by a waterproof housing. Control panel and expansion tank can mount left or right.
Volcanic - a soundname in Marine Heatersriding the waterways foryearsA Volcanic marine heater is noordinary thermal fluid heater.It's a durable long lasting workhorse unlike most "land based"designed heaters. And,Volcanic still uses the originalHopkins design helical coilconcept.
Volcanic heaters have been workingthe Canadian and American water-ways from coast to coast for years.
These hot oil helical coil designheaters are designed and built, infact, overbuilt, for years of hard workon asphalt barges, tank farms, any-where heat is needed to deliver thegoods.
Volcanic heaters are used with unattend operation.
1 The burner and electrical control panel are protected by awaterproof housing for on deckusage. Control panel meets NECand UL Codes.
2 High combustion efficiency isobtained by pressure atomiza-tion of fuel oil and high pressureair. An electric pre-heater heatsthe residual fuel oils for properatomization.
3 Electrical panel meets allrequired codes and can bemounted on either side of theheater package.
4 Optional controls provide fullmodulation with low fire startand up to 6:1 turn down ratio.Burners meet USCG requirementsand ABS on request.
5 Extra heavy steel cylindricalshell surrounds the helical single
or double wound coil madefrom Schedule 40/80 seamlesspipe. Spacers separate the coiland shell.
6 The shell is covered with lay-ers of ceramic fiber blanket insu-lation. A rigidizer is sprayed onthe surface to protect againstvelocity of exiting gases.
7 Helical Coil - single or doublewound designed by Volcanic.
8 Access door allows for inspec-tion and maintenance tasks.
9 Observation port allows forchecking flame pattern andflue combustion conditions.
10 Separation/surge tank velocityof thermal fluid returning fromthe system is decreased to allowany steam or air in the system toescape into the expansion tank.
11 Expansion Tank - as the system is brought up to operating temperature, heated thermal liquid expands into the expan-sion tank from the separationtank. Thermal liquids expandapproximately 4% by volume foreach 100oF temperature increase.When the system is shut downand the liquid cools, liquid iswithdrawn from the expansiontank to maintain a filled circulating loop.
12 Cold Seal Tank - The thermalliquid system is vented to theatmosphere through this tank toexpel air and any steam duringsystem start up.
13 Circulating Pump - A centrifu-gal pump is used to supply thermal liquid for the entire system. Pumps are selected tomeet flow and pressure droprequirements of the system.Pumps are jacketed for watercooling when thermal liquid inthe pump is above 350oF whenrequired.
Miles of barge heating piping carries hot oil to userswith minimal to no pressureWith steam* at 338oF (170oC), a pressure of 100 PSIG (7 bars) isrequired and at 572oF (300oC)the pressure rises to nearly1500 PSIG (105 bars).With thermal fluids, these temperatures are achieved
at low pressures and system pressure drop for pump circulation of the fluid is the only governing factor.

Features of the standardsafety and limit controlsFlame Program & SafetyControl - The flame program con-trol provides for ignition and flamefailure protection for automaticallyignited burners. With limit, operat-ing controls and interlockingdevices, the control automaticallyprograms the operation of burner-blower motor, ignition, fuel valvesand modulator.
Low Flow Cut Out - Protects theheater and the fluid. This differential pressure switch measures pressure drop throughthe heater coil, indicating flow.Low flow will shut down theburner. (Manual reset).
Low Level Control - This floatcage type switch is usuallyattached to the expansion/surge tank. It will shut the burn-er down on low liquid level andturn off the red limit light, andwill restart the burner when theproper level has been returnedand reset.
High Temperature Cut Out -The sensing element is located inthe heater fluid line. The setpoint which is set by factory tech-nician to customer and USCGspecifications, should never beabove the maximum tempera-ture permissible for the fluid usedin the system. In case the setpoint is reached, the instrumentwill shut the burner down.
Low Fuel Oil Pressure Cut Out -Control shuts off the burner if thepressure in the fuel oil supplyline drops below the minimumrequired for proper atomization.
Alarm circuit and Signal Light -The burner wiring is arranged insuch a manner as to ring analarm in case of flame failure.Manual resetting is required. Incase of "flame failure" the buttonon the flame program controlmust be pushed. All other limitsafety switches will only ener-gize the red limit light if closed.Once the cause of stoppage iseliminated, the burner willrestart after resetting.
Low Fire Interlock Switch -This switch is part of the mod-utrol motor, and serves as a safe-ty interlock which will preventthe burner from starting unlessits components are set to provide"low fire" only. This provides forsafe ignition.
Volcanic personnel work with the customer, creating layout, piping, and heat requirements to produce a totally efficient system.When a shipyard sets out to build a vessel, a barge, Volcanic engineering and system designers will work with the customer toget the job done.
Sizing of the heater, the helical coil, the pumping, the piping package, taking into consideration the vessel's holding size - everything is calculated. And when it's all sized right and up and running, we at Volcanic know it's a precise and highly efficient system that will perform without flaws for many years to come.
Volcanic's Packaged System
Skid mounted heaters are completeunits containing all operating controls
and instruments. Installatin time is minimizeddue to quick connections for power leads,
fuel lines, stack, and thermal fluid piping lines.Volcanic service engineers complete on site start up
and go through maintenance procedures with the customer.
