Marine Equipment Sector Marine Boiler Burners & Incinerators

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 bilge / slush treatment 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.

Main boiler burner

For LNG carrier   Oil/Gas combination burners for main boilers   Type: SFFG II


This burner was designed and developed for the main boiler on LNG carriers and is currently being used by many LNG carriers. The boil-off gas from the LNG tank can be used as fuel, and it can also be combined with oil fuel for mixed combustion. The operation efficiency has been improved. This burner can also be configured as a single-fuel gas burner to reduce the impact on the environment and is ideal for complying with the tightening of regulations (for NOx and SOx, etc.) in the future. This burner offers excellent load-following performance, high load combustion, energy savings and a reduced environmental impact. Currently, its application is not just limited to LNG carriers but is also extending into other offshore fields, such as FPSO and FSRU.
