BOS Emulsified Fuel System improves the combustion efficiency by producing stable water-in-fuel emulsions to improve injector fuel atomization.
The key success factor in emulsified fuel is the ability to produce and maintain the optimum 10% water as water-in-fuel particle sizes of 2-8 microns. This is achieved with our patented BOS Emulsifier that unlike other systems in the market, has no moving, cavitating or vibrating parts. The performance of our EFS has been verified by ship owners, classification societies and engine manufacturer Wärtsilä. The system can be operated using multi-fuels like HFO, IFO, MDO, MGO, ULSFO and new ECA. There is no use of any chemical additives.
THE SYSTEM COMES IN TWO MODULES: WATER CONTROLLER MODULE AND EMULSIFIER MODULE
EASY AND TROUBLE-FREE OPERATION
BOS Emulsified Fuel System is designed to be easy to operate. It is fully automated and fail safe with safety interlock built in
In the case of an alarm, the system will automatically switch off the HP water pump and the auto change over valves will switch back to normal operation and bypass the emulsifier (see the picture on the left).
Touch screen control panel
BOS EFS control panel has an intuitive menu making very easy for the user to set up the system. Reports, historical trends and logs are also provided by the controller. The system can be integrated into the ship’s engine room control system. There is password protection for the key setting.
EASY AND FAST INSTALLATION
The ship does not need to dry dock. Retro fitting is done when the ship is at the port. Three by-pass valves would be installed to the fuel line by retro-fitting a small section of the FO pipe (between the circulation pumps and heaters) that would take only about 3-6 hours. The whole installation would be completed after that without interrupting the ship’s operations.
Note: A new flow meter may be required if the existing one is not accurate enough (+/- 0,5%) and/or does not provide flow rate measurement.
