dreizler marathon® Duobloc -
oil burner up to 44 MW



This burner series is constructed in a Duobloc system: The blower unit for supplying the air for combustion complete with motor and the burner with air housing and burner head comprise two units.

The combustion of fuel achieved by dreizler® ARZsuper flue gas recirculation with a control ratio of 1:10 facilities a very economic combustion accompanied by low emissions. The flame rotates and fully combusts the fuel rapidly and intensively.

 


Flexible assembly

The marathon® oil burner Duobloc can be supplied with combustion air from a blower mounted separately in a lower floor, in an upper floor or situated directly in front of the boiler. The air housing can be arranged with different exit angles set at steps of 22,5°.

You profit by the highly flexible assembly of the basic burner and of the ventilator relating to your requirements. You decide on the various assembly possibilities on site and so you optimise the burner installation at your heat generator.

 

High efficiencies with excellent dreizler® hightech

Your advantages on oil operation:

  • 2-step or 3-step with simplex nozzles
  • or modulating with spill back nozzles and elektronic linkage
  • Speed control frequency and saving up to 80% current consumption
  • Residual oxygen control oxygen

 


marathon® burner technology

Continuous burner output control between minimum and maximum flame via pneumatic linkage.

 


marathon® fan

Ventilator separately mounted to base frame with vibration absorber, fitted with electro motor and fan wheel in steel panel housing.

 


marathon® oil fuel equipment

Separate fuel high pressure regulating station with oil pump and protective equipment according to EN 267, mounted in oil pan, with hose connectors flow/return, 3-4 oil solenoid valves, overflow valve or oil regulation, oil manometer flow, oil pressure switch min./max.

 


Retrofit of a gaseous fuel 

The optional retrofit for a dual fuel burner with a gas train for gas operation instead of oil operation is always possible subsequently.

 


Noise reduction

marathon® burners operate fascinatingly quiet. Very often no further noise reduction measures are required. An additional burner noise reduction of up to 20 dB(A) can be effected by noise dam caps made from steel plate.

 


Assembly - quick and easy

dreizler® Duobloc burners are ready wired ex works and are checked on function and safety according to strict factory specifications before delivery.

 


Range of capacity Duobloc oil burner

Series marathon® MC 10003.1-L up to 10003.8-L

The type series marathon® Duobloc oil burner MC...-L  is available in the low emission version ARZsuper complying with the NOx emission limit values.

 

dreizler® guarantees premium quality and high safety. We gladly plan and realise individually the best installation for you.
