COMBUSTION CONTROL SYSTEM
Automatic control system tends to be more massive in function andmore complicated in the system in order to improve safety and easy
operation. We consider it as the key words that how easily we canhandle this modern system.
We have developed graphical touch panel for burner control in order
to meet needs of the age. New functions help ship crews supporting
maintenance operation, running adjustment, early detection oftrouble and decrease of trouble made by wrong operation and badadjustment and also it enables improvement of the burner system
control and burner combustion itself for easier operation.

R O TA R YCUPBURNER

Why is "Sunflame rotary cup burner" required now and in the future ?
「What is demanded now ? What will be demanded in the future? 」
These are what we have been focusing on since the beginning of our business and are our attitude toward production that does
not change in the past, now and in the future.
Since our establishment of the company, we believe that Sunﬂame rotary cup burner, one of our highly recommended products, isthe best choice for Aux. boiler in marine industry which consumes high viscosity fuel in terms of safety, eﬃciency and “combustioncomponent needed in the future” which is the most suitable in circumstances of all the more severe aspects and safety aspect
as well.

What is rotary cup burner?
Fuel oil is guided to inside of the cup spinning in high speed, formed thin ﬁlm by centrifugal power, hit by high air pressure foratomization. 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 cupburner does not need to have this small hole due to above mechanism, and can accept wide viscosity range of fuel. There is noconcern of fuel oil stuck during heavy fuel oil burning and the rotary cup burner can obtain stable combustion for long period.
Additionally one of big advantage is easy handling at start of burner in cold condition and while continuous running, in a range
from small boiler to large boiler. Because it does not require any special procedures nor maintenance due to no assisting steam forcombustion. Another advantage is to dispose waste oil which generates onboard.
Wider range of viscosity can be accepted for the fuel oil applying to the rotary cup burner. Recently we have to switch two fuel oils
which have totally diﬀerent characteristics: one is low-sulphur low-viscosity good-quality fuel oil used in emission control harbor
areas and the other is high-viscosity heavy fuel oil used in other area. Because wider range of viscosity can be accepted in the fueloil applying to the rotary cup burner and as it does not require oil pressure for atomization, the complicated adjustment ormaintenance jobs are not required when you switchover the fuels. It would require only minimum adjustment and can be handledeasily.

MGO The most suitable burner to burn “MGO”
We are entering into a new environmental protection requirement to burn low sulphur content fuel oil at certain restricted areas. It is MGO, extremely
low viscosity oil and the ships shall ﬁre two totally diﬀerent kinds of fuels switching over with heavy fuel oil of high viscosity oil.
Sunﬂame rotary cup burner, capable to accept quite wide range of viscosity oils, does not need special counter-measures such as complicatedoperational procedures nor replacement of parts/components when switches over and burns these two diﬀerent fuels safely.
In case you take Sunﬂame rotary cup burner now and you intend to ﬁre MGO in the future, you do not require any special changes, and can still use
the system as is. Hence it is simple, safe, eventually lower cost and the most suitable burner to meet and satisfy present environmental requirement.

Easily switching over the fuels?

Sunﬂame rotary cup burner can manage this, same way as conventionaluse of diesel oil& heavy oil. It does not require replacing nozzle fordiﬀerent viscosity fuel, no need to use special pumps, nor necessary
managing delicate adjustment of atomizing oil pressure to keep same
capacity, diﬀerent from the cases of other type of burners such aspressure atomizing burner and steam atomizing burner.
Rotary cup burner can accept wider range of oil viscosity, and can burn
HFO at rather lower temperature than other type of burners. It resultscomparatively safer operation at changing fuels.

Needs to change system to comply with MGO ﬁring?

・ One of the advantages of the rotary cup burner has been able to accept
wider span of viscosity for ﬁring and even for much lower viscosity oiluse, it can accept without special conversion of parts/components.
・ Fuel oil pump can handle oil at low pressure (0.15 ~0.5MPa) and canmanage handling MGO/MDO and HFO by same pump.
・ Rotary cup burner does not require steam for atomization and no needto redesign fuel oil supply line and high temp. steam supply line, norapply special MGO compliance parts.

EMULSION COMBUSTION SYSTEM (OPTION)
Emulsion combustion system as an optional devise, has successfully developed in order to bring out maximum
performance of rotary cup burner from high viscosity oil combustion with accurate adjustment of air/fuel ratio.
Also this system oﬀers reduction of soaring fuel expenses and of environmental gas emission which will become Oil droplet Water particles

This system, designed compact and used for marine Aux. Boiler, can be installed in the existing system & layout without changing much of F. O. operation
arrangement. (Water supply line to be added) Automatic control system with graphical control panel is adopted to make operation / handling simpler.
This control panel is a standard arrangement.

Can burn fuels safely?

・ No special extra procedures and counter-measures are required, hencecrew can handle the burner, same way as usual meaning less chance totrigger mistakes.
・ Not like pressure atomizing burner of which system requires high oilpressure (1.5~2.0MPa), we give low oil pressure (0.15~0.5MPa) andeven if MGO splashes at leakage, it is not fatal.
・ When two diﬀerent quality fuels are mixed, there is a possibility ofcreating sludge, but as there is no nozzle in rotary cup burner, it is notprobable to suﬀer from ﬂame failure caused by choking of oil passage
with sludge.
・ Rotary cup burner does not use atomizing steam for MGO, by the way
it is not allowed to use steam unless it is designed to do so, hence
Sunﬂame rotary cup burner is safe in operation.

Fuel saving :Water particles are evaporated in furnace high temp zone andmade micro explosion, resulting better atomization.

3rd generation rotary cup burner
Some concerns that rotary cup burner requires much maintenance due to many components and also it seems diﬃcult to adjust
oil/air ratio in case unbalanced, although it is obvious that rotary cup burner is safe and high performance.
Sunﬂame rotary cup burner overcomes these anxieties by the results of continuous development such as simpliﬁed structure andnew original control system which brings out maximum performance. The number of delivery of Sunﬂame rotary cup burner isincreasing rapidly and we have received reputation of high reliability and the best burner for easy operation to high performancesince development of 3rd generation rotary cup burner.
