Because we have struggled with high-viscosity heavy fuel oil used for marine since establishment of the company, we are convinced that the Rotary Cup Burner is the most suitable to burn it surely and safely adopted on aux. boiler, etc. We are confident that the Rotary Cup Burner improved again and again based on our long experience performs perfect stable combustion for your satisfaction. The Rotary Cup Burner is the core competence of our company.

Fuel oil is guided inside of cup spinning high speed, formed like thin film by centrifugal power, hit by high air pressure for atomizing. It is the mechanism of rotary cup burner.
The Pressure Jet Burner atomizes fuel oil by high oil pressure through very small hole of nozzle tip. Comparing to it, the Rotary Cup Burner does not need to have this small hole due to above mechanism of the Rotary Cup Burner. There is no concern of fuel oil stuck during heavy fuel oil burning and the Rotary Cup Burner can obtain stable combustion for long period. Also wider range of viscosity can be accepted for the fuel oil applying to the Rotary Cup Burner.
Once the Rotary Cup Burner was spot-lighted at the time of the second oil shock from 1979 for the ability to burn the sludge oil in marine aux. boiler. Though the numbers of application of sludge oil burning are reducing presently due to the increase of maintenance job inside of boiler, many customers still keep using the Rotary Cup Burner continuously evaluating its high performance and easy handling.
Recently we have to switch two fuel oils which have totally different characteristic: one is low-sulphur low-viscosity good-quality fuel oil used in emission control harbor area and other is high-viscosity heavy fuel oil used in other area. Because wider range of viscosity can be accepted for the fuel oil applying to the Rotary Cup Burner and it does not require oil pressure for atomizing, the complicated adjustment or maintenance jobs are not required when you switch the fuels. It would require only minimum adjustment and can be handled easily.
We adopt this Rotary Cup Burner also for sludge oil incinerator, which enjoys its very good reputation to dispose the sludge oil without adding expensive Diesel Oil.

Sometimes we hear unnecessary rumor for Rotary Cup Burner.
“Although the Rotary Cup Burner is safe and high-performance, it has a lot of parts need to be maintained.” “The adjustment of fuel/oil ratio is difficult, if its balance is lost.” However, Sunflame’s Rotary Cup Burner has overcome such concerns simplifying the construction and adopting unique automatic control system, which ensure maximum performance. Presently our Rotary Cup Burner has been evaluated as most reliable and most easy-handling burner anyone can operates with maximum performance. The burner delivery records and delivery ratio of burner type shown below prove it.
