Volcano Burner
Spare Parts Supplier
Marine boiler burners from the Japanese maker Volcano, the SFFG II and Vignis dual-fuel types among them, read from the burner's own plate, so tips, gas side items, ignition parts and flame monitoring items are quoted for the burner that is actually fitted.
Volcano burner types behind parts enquiries
Volcano Co., Ltd. is a Japanese maker of combustion equipment for ships and for industry ashore, burners for marine boilers among them. A Volcano burner is normally found on a boiler built by another maker: Mitsubishi's brochure for its dual-firing auxiliary boilers names Volcano as one of the two burner makers. The cards below cover the two Volcano burner types named in that brochure, SFFG II and Vignis.
SFFG II
In Mitsubishi's dual-firing auxiliary boiler, SFFG II is the Volcano dual-fuel burner listed for the larger boiler sizes, and it can fire oil alone, gas alone or both together. Mitsubishi writes the type as SFFGII, and it is also seen with a space as SFFG II. Copy it the way the burner plate reads, with the serial number, because the oil side, the gas side and the flame monitoring items are all listed against that particular burner build.
Vignis
Vignis is the Volcano dual-fuel burner that Mitsubishi lists for the smaller sizes of the same boiler, with a Sunflame SDR burner as the other choice there. It is a type of its own, not a smaller SFFG II, so an item is never carried from one parts list to the other just because both burners fire the same fuels. Where the boiler documents name both Vignis and SDR, the plate on the burner front shows which one was fitted.
Boiler plate, gas valve unit, other burners
The boiler is read from its own maker's plate. On a dual-firing boiler the gas valve unit and its enclosure can come with the boiler rather than with the burner, so its items are read from the unit's own label. A burner of another make on the same boiler goes to that maker's page, for example Sunflame, Saacke or Riello.
What puts a Volcano burner on the requisition
Most burner requests start with a flame that looks wrong or a burner that trips. The pattern below helps to name the right group of parts before the request is written.
Worn or coked oil tip
A tip that has worn or coked spoils the spray, and the flame shows it as smoke, a lifted flame or carbon on the furnace wall. The tip is renewed against its marking or its item number, never by a bore size judged by eye.
Late or failed light-off
Ignition electrodes, the ignition transformer and, where the burner has one, the pilot burner decide whether light-off is clean. Look at the burner front before listing ignition items: a burner that lights straight from its electrodes has no pilot burner parts to order.
Flame failure trips
A sooted detector window or a relay near the end of its life can stop the burner on flame failure while the flame itself is sound. Clean the window and test the detector before anything is ordered; if the trip comes back, put the detector, the flame relay and the burner management unit on one request, each with its own marking.
Dual-fuel burners running on gas
On SFFG II and Vignis burners the gas nozzles belong to the gas side and sit in their own group, apart from the oil gun. State the firing mode at the time of the fault, oil, gas or both, so the part is looked for in the right group of the parts list.
Volcano burner items that appear on RFQ lines
Grouped the way a boiler burner is assembled. Naming the group on each request line saves a round of questions.
- Oil guns, atomisers and nozzle tips
- Atomising steam or air items, where the burner's atomiser type uses them
- Gas nozzles and gas side items of dual-fuel burners
- Ignition electrodes, ignition transformers and pilot burner items
- Flame detectors and flame relays, by the type in the parts list
- Burner management unit and control items, by the type on the unit
- Burner fan, air register and damper items
- Fuel valves, solenoid valves and pressure switches
- Burner tile, gaskets and seals of the burner front
Reading a Volcano burner plate and manual
A Volcano burner part is priced from the burner plate and the burner manual, not from the boiler. These details let the request be worked without guessing which burner is fitted:
- Burner type exactly as stamped on the burner plate, every letter included, and the burner serial number
- Atomiser type as the plate or the manual names it, for example pressure jet or steam-assisted, and the atomising medium if the burner atomises with steam or air
- Nozzle and tip marking, or the item number of the tip in the parts list
- Flame detector type from the detector body and the type printed on the flame relay
- Burner management unit type from its own label, and who supplied the panel if the manual says so
- Firing mode in use when the fault appeared: oil, gas or both
- Boiler maker and boiler type from the boiler plate
- Item numbers and the parts-list or drawing number from the burner manual
- Photographs of the plate, the burner front and the removed part, and the delivery port
How a Volcano burner request is worked
Each line is reviewed as a genuine part or a checked alternative, confirmed before the quote. For a Volcano burner the review starts from the burner plate, because the same part name stands for different items on an SFFG II and on a Vignis.
Flame detectors, relays and burner management on the OEM route
These items prove the flame and shut the fuel off when it fails, so each is quoted only for the type named in the parts list or marked on the removed unit. A detector, relay or controller that merely looks similar in a photograph is not offered.
Tips and atomisers against the listed item
A tip or atomiser is matched to its item number or its marking, together with the burner type and serial. Two tips with the same thread can spray quite differently, so the listed item decides.
Catalogue items behind a Volcano number
Some lines in a Volcano parts list are ordinary seals, gaskets or bearings. If the owner agrees, these can be offered as checked alternatives, but only after the dimensions and the material are taken from the parts list or measured on the removed part.
Burner list and boiler list
Shell, tubes, mountings and level control are ordered from the boiler maker's documents; gun, tip, ignition, fan and flame monitoring from the burner's. On a dual-firing boiler the gas valve unit may belong to the boiler supply, so its plate is read on its own.
Volcano burner parts — questions from chief engineers
The boiler plate reads Mitsubishi. Why is the burner read as Volcano?
Because the burner is a separate unit with a plate of its own. For its dual-firing auxiliary boilers Mitsubishi names Volcano or Sunflame as the burner maker, so the boiler plate says little about burner parts. Send a photograph of each plate; boiler items go through the boiler parts page.
Our documents say SFFGII, the plate says SFFG II. Is that a problem?
No. Both spellings are met, and Mitsubishi writes the type without the space. The plate still decides, so copy it exactly as stamped, with any letters or figures that follow, and add the serial number of the burner.
The boiler documents offer Vignis or SDR. How do we tell which burner is on board?
From the burner front. For the smaller sizes of its dual-firing boiler Mitsubishi lists both a Volcano Vignis and a Sunflame SDR, and the two come from different makers with separate parts lists. The plate on the burner settles it; an SDR is read on the Sunflame page.
Which flame detector and relay details should I send?
Photograph the labels of the flame detector, the flame relay and the burner management unit, and type out what each one reads. These lines are priced on the OEM route, and only for the type in the parts list or on the removed unit.
Can a nozzle tip be quoted from a photograph?
A photograph helps to recognise the part, but a tip is fixed by its marking, by its item number in the parts list or by the burner type and serial. Tips that look alike can spray differently, so none is matched by appearance alone.
Is Vessel Core connected to Volcano?
No, and there is no agreement of any kind. Vessel Core holds no distribution, representation or partnership agreement with Volcano, and quoting a component against one of its designations implies no approval by the maker and no claim of interchangeability.
Start with the burner plate.
Send the burner type and serial number as stamped, the firing mode in use, the tip marking, the labels of the flame detector, the flame relay and the burner management unit, and photographs of the removed parts. Every line is placed in its burner group first, and only then is a part reference matched to it.
