Volcano Vignis For LNG Fueled Vessels

Manufacturer: Volcano Co., Ltd.
Model: Vignis

Features

Gas/Oil simultaneous mixed combustion
Fuel can change automatically and safely because it is capable of burning Gas and Oil simultaneously.
“Vignis” contributes to zero methane gas release into the atmosphere because it equips GCU mode by the simultaneous mixed combustion.

- GCU mode
  All types of “Vignis” equips GCU mode as a standard specification in addition to the boiler mode.
  It contributes to simplify device configuration and in some cases, no need to install GCU by using GCU mode.
- Combusts gas of any ratio
  “Vignis” is capable of treating inert gas up to 100% content due to Gas/Oil simultaneous mixed combustion.
- Wide turndown ratio “10:1”
  “Vignis” reduces heat loss by decreasing frequency of both firing and extinguishing due to wide range Turndown Ratio up to 10:1
- Compatible with a wide range boilers
  “Vignis” is applicable to boilers with evaporation rate of 1 to 7t/h
  Gas/Oil simultaneous mixed combustion DF burner “SFFGⅡ” can use for boilers which evaporation rate is higher than 7t/h.
- Completely compliant with international standard IGF code^*1 and IGC code^*2
  Based on 38 years of experience in gas combustion on vessels,Volcano DF burner is completely compliant with international standard IGF code and IGC code.

*1 GF CODE : International Code Of Safety for the ships using Gases Or other Low-Flash Point Fuels.
International standards applicable to LNG fueled ships.

*2 IGC CODE : International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk.
International standards applicable to LNG carriers.

Specification of Vignis-W (wide range type)

Parameter	Value
Evaporation rate	For 1.0 to 2.0 t/h
HFO Max. Combustion Rate	100 to 190 kg/h
MGO Max. Combustion Rate	95 to 180 kg/h
Gas Max. Combustion Rate	80 to 150 kg/h
Turndown ratio (gas)	10:1
GCU mode	Gas Max. Combustion Rate: 240 to 450 kg/h
Wide range type (Vignis-W)	Gas combustion amount for GCU mode is three times higher capacity than normal operation. That can reduce working hours when LNG fueled vessels and bunkering vessels are gas freeing.
