We have a wealth of experience dealing with burners and other systems used on vessels: from boiler burners used for the main propulsion engine on large LNG carriers, to auxiliary boiler burners used as heat sources within the vessel, as well as waste liquid incinerators, and waste oil / sludge processing systems. We offer products with excellent energy savings and environmental performance in conjunction with a global service network in order to support safe and efficient marine transport.
Overview
Gas/Oil simultaneous mixed combustion DF (Dual Fuel, which means gas and oil) burner for boiler of LNG (Liquefied Natural Gas) fueled vessel "Vignis" has Gas/Oil simultaneous mixed combustion mode as well as HFO-mono, MGO-mono and LNG-mono combustion mode.
Gas/Oil simultaneous mixed combustion mode can efficiently utilize BOG as fuel and shortage of calorie can be fulfilled by “Fuel Oil”. Because combustion condition is stable even at Gas/Oil simultaneous mixed combustion mode and fuels can be easily changed over,and also it is useful in preventing human error.
The new "Vignis" equips GCU mode. And a boiler which is equipped "Vignis" can be used as GCU(gas combustion unit).
Also, the wide range type is possible to process more boil off gases.

- 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.
Features
- Gas/Oil simultaneous mixed combustion
Fuel can be changed 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 be used for boilers which evaporation rate is higher than 7t/h. - Completely compliant with international standard IGF code*1 and IGC code*2
