DF Burner for Boiler

What is a DF burner?

A DF (dual-fuel) burner is a combustion apparatus that can use low-carbon gaseous fuels such as LNG as well as petroleum fuels.
It can be used not only as a heat source for auxiliary boilers, but also for the disposal of BOG as well as excess gas during bunkering.

Features

Sunflame's DF burner is the rotary cup burner with integrated gas nozzles for stable combustion. Controls for rotary cup spinning speed, primary air for atomization and secondary air for combustion are just as effective for gaseous combustion as petroleum fuel combustion.
The software also improves its conventional capabilities. The control panel, equipped with a graphical touchscreen, has been designed to facilitate complicated oil and gas controls. A remote monitoring service via ship-to-shore communication is also available for optimal operation of the DF burner.

  • 01Flexible Controls

    Stable combustion by automated control of rotary cup spinning speed, primary air for atomization and secondary air for combustion

  • 02Fuel Saving

    Reduction of frequent start/stop operation by broader combustion turn-down ratio

  • 03Contribution to Low-Carbon Society

    Minimized fuel consumption by automatic oil fuel control based on the inert gas mixing ratio during GCU mode

  • 04Data Utilization

    Equipped with the devices required for the use of the Sunflame Smart Support System.

    *Additional service fees apply.

05Combustion Modes

  • Sunflame's DF burner features 4 different combustion modes.
  • It can be used as a heat source for auxiliary boilers on LNG powered ships through oil or gas fuel combustion as well as dual fuel combustion.
  • BOG (Boil Off Gas) and purge gas which results from bunkering can be processed at a free flow pressure (under 0.01MPa) using the GCU mode.

06Maintenance

  • Return piping is not required as both the main line and the ignition burner line use one common line. Since the ignition burner pipeline is operated at a low oil pressure of 0.3 MPa, it minimizes the number of components and consumable parts, making maintenance simpler.
  • For maintenance purposes, the burner is accessible by simply opening the hinged door.
  • The GVU is equipped with a valve control function and can check gas leaks and location instantaneously. Details

07User-Friendly Control Panel

Complex oil and gas controls made simple for anyone to use.

  • Visualizes the operation of the burner, the condition of the boiler and fuel control valve, and more
  • Operate and switch from one mode to the next using a touchscreen control panel
  • Displays troubleshooting procedures and caution alert for safe operation
  • Optimum air-fuel ratio of each control table for atomizing air, combustion air, spinning speed and oil flow
