Sunflame's Core Combustion TechnologyAuxiliary boilers are crucial on-board devices which operate during berthing and sailing. Theburner apparatus, which serves as the auxiliary boiler’s heat source, must guarantee reliable operation
for an extended duration of time even under demanding conditions at sea.
With increasingly strict international environmental regulations, ocean-going vessels today must becompatible with different fuel types suitable to each maritime zone.
Sunflame’s Rotary Cup Burners are capable of atomizing fuel consistently irrespective of the fuel’squality or viscosity, including challenging fuels like waste oil.
Moreover, the pivotal elements of combustion—combustion rate, atomizing air pressure and volume, androtary cup rotation speed—are all modifiable via software. This adaptability ensures stable combustion
throughout all phases of ship operation, eliminating the need for intricate manual adjustments.
These capabilities are not only beneficial for managing conventional heavy fuel oil but also for gaseous
fuels such as LNG and ammonia, as well as alternative fuels such as methanol.
With decarbonization of the marine industry in mind, Sunflame is committed to product development inresponse to customer demand using Rotary Cup Burners.

Mechanism

A Rotary Cup Burner is the ideal burner for marine auxiliary boilers, designed for efficient combustion
by controlling the rotation of the cup and two types of combustion air.

Advantages

Operation
The risk of fire caused by dispersion is reduced
due to low atomization pressure at 0.15-0.5 MPa.

Secondary air

airfuel oilOil feed pipe
1 Fuel oil is conveyed into the cup that is rotating at high speed.
2

Enables stable combustion over an extended
period of time with little risk of misfire from clogging.

Primary airrotator

ROTARY CUPAchieves fuel efficiency with wide turn-down
ratio: the amount of fuel for combustion iscontrolled to be minimal based on steam
demand.

Safety andstability
2Centrifugal force forms
a thin film of oil.

Compatible with a wide range of fuels such as
HFO, MGO, biodiesel, methanol, and waste oil.
LNG and ammonia can also be combusted
when equipped with gas nozzles.

Maintenance is simplified because themotor is directly connected to the shaft ofthe cup, the piping unit is a block unit andthe main burner unit is attached to a hinged
door, making it easy to open.

Minimizes heat loss in the boiler furnace byeliminating the need for surplus combustion air.

Redundant system with PLC and relay typecontrol for semi-automatic operation even incase of PLC failure.

MGO Automatic Switching Unit

ROTARY CUP BURNER

Support /Option

Boiler burner fuels such as HFO and MGO can be changed easily with asingle switch to comply with sulfur oxide emission regulations in bothEmission Contol Areas (ECAs) and Non-ECA zones.
By using the MGO main piping also for the ignition burner piping, the need for pipe modification isminimized, and fuel waste is reduced by switching fuels just before the burner. Fuels can beswitched quickly and without error because complex valve operations are not required.

Control Panel
The control panel is equipped with an intuitive touchscreen to visualize its multifunctional auto-control system.
By enhancing the control panel's operability, we not only improve its functionality but also ensure that
operational data can be used to provide optimal support for operations and prevent potential issues.

Faster changeover than conventional systems

Compatible with a wide range of fuel viscosities*For technical opinions on the handling of MGO, such as whether or not an MGO cooler is required,please contact the boiler manufacturer separately.

Emulsion Combustion System（ECS）

Sample image of main screen①Data logging function

Precise troubleshooting can be provided by visualizing operational data,
which enables a clear understanding of the trouble situation.

Sample image of troubleshooting display②Troubleshooting display

Prompt resolution onboard is ensured by displaying theappropriate response methods for each incindent.

This system creates a state close to theoretical
combustion by introducing water into the fuel oil andcreating finely atomized oil using the micro-explosions
from water evaporation.
It is possible to maximize the characteristics of a rotary cup burner, which
excels in the combustion of high-viscosity oil and fine adjustment of air-fuelratio.
By reducing excess air, it is possible to decrease heat loss within the boiler
furnace, thus improving combustion efficiency and reducing theenvironmental impact of emissions such as NOx.

Sunflame Smart Support System
Real-time IoT technology captures the vessel
equipments' operational data and visualizes
the operational status. We offer suitable
maintenance strategies, trouble prevention,and operational guidance that enhances fuelefficiency by analyzing the parts sales history
and service reports. (Network facilities arerequired on the vessel side to conduct
ship-to-shore communication.)

Additionally, as it is designed for installation in auxiliary boilers, it iscompact and can be installed with minimal changes to the heavy oil piping
facilities and layout, aside from an additional water supply piping.

Fine water particles

Micro explosion

Combustion principle① Fine water particles are introduced into the fuel oil.
(20% water is added)② Fuel oil is dispersed into fine particles when the water particles
explode by evaporating in the heated boiler furnace.

Benefits
Fuel consumption rate

Oil

③ Finer oil particles increase the total contact area with oxygen,thereby optimizing the combustion process.
⇒ By improving combustion efficiency, excess air is reduced
and boiler heat loss is minimized.
