F096
Fig. 3: Functional diagram, example model HLG (for the combustion of oil and gas)
1 Combustion air
2 Gas
3 Oil
4 Core air
5 Secondary air
Eurotherm burners have been designed for the combustion of the following fuels:
Eurotherm HL: fuel oil EL3
Eurotherm HG: natural gas3
Eurotherm HLG: fuel oil EL and natural gas3
Their design and function meets the requirements of DIN EN 267/ 676 and of thegas device guideline, they have a corresponding CE approval as monoblockburners for fuel oil EL and natural gas.
The fields of application of Eurotherm burners are steam/hot water boilers as three
pass and reverse flame boilers and thermal oil boilers.
Any mounting position is possible for gas burners; however, it has to be ensuredthat the gas axis is horizontal.
Oil burners and dual-fuel burners must only be used with horizontal burner and fanaxis or alternatively as top-fired burners.
The furnace has to be dimensioned such that the prescribed emission values(see chapter "Furnace dimensions") are met.

Eurotherm Design And Function
2011-02-21
Technical Documentation
3.2 Design
Eurotherm burners consist of the so-called mixing system and the housing.
Fan, air control dampers, fuel-air compound control and burner control (oroptionally the unit connection box) are integrated in the housing.
The mixing system includes the fuel connections and is used to guide and centerthe gas head or the oil lance. Moreover, it includes the moving stabilizing disk.
The individual components of the burner are arranged such that services can becarried out without any problems. Oil lance, gas head or stabilizing disk can beremoved for maintenance service in turned-out conditions (without removing theburner from the boiler). The oil lines do not have to be separated.
For more detailed information please refer to the burner operating instructions.
The burner is wired, completely ready for connection.
For mounting a flange seal the burner head insulation and fixing screws areincluded in the scope of delivery.
3.3 Equipment
Eurotherm burners are designed in monoblock construction. The equipment variesdepending on the application (natural gas, fuel oil EL, combined operation). Pleasefind below a list of some important equipment features which belong to the seriesequipment or which are available alternatively or in addition:
Light metal burner housing which optionally can be turned to the left or to theright side, with integrated, directly coupled radial fan
For gas firing operation: Precision mixing system with integrated gas lances
and a central gas pre-mixing zone For oil firing operation: Return flow pressure atomizer for fuel oil EL for
optimum adjustment to the furnace
Electronic fuel-air compound regulation with integrated automatic firingsequence controller or mechanical fuel-air compound regulation in two-stageor modulating operating mode (see also chapter "Technical data")
Flame monitoring system and automatic firing sequence controller foroperation with or without supervision
Capacity-specific air optimization by means of axially mobile stabilizing disk
Directly acting high voltage ignition system with noise suppression
The required components for the oil supply matching the burner program and theDVGW-tested gas valve trains are also available with SAACKE.
Warning!
The Eurotherm gas burners (HG and HLG) may only be operated if two Class Asolenoid gas valves are integrated into the gas valve train.
Each time before firing the burner, the furnace must be sufficiently purged.

3.4 Air and Fuel Flow in the Burner
3.4.1 Combustion Air
The air rate is dosed via air control dampers.
By axial travel of the stabilizing disk the combustion air is controlled to optimumspeed, depending on capacity stages. The Eurotherm burners are provided with anautomatic air seal to minimize the standstill loss.
3.4.2 Natural Gas
The natural gas is dosed via a gas control damper which is integrated in theburner, and it is discharged via a multi-stage gas head. For the connectionpressures please refer to the chapter entitled "Technical data", section "Burneroperating data".
In gas firing operation, ignition is direct and electrical.
3.4.3 Fuel Oil EL
The extra-light fuel oil EL is supplied to the burner via a high-pressure pump. Theoil flow rate is dosed via the oil flow controller (in the return flow of the burner).
In oil firing operation, ignition is direct and electrical.

6 Mounting Instructions / Construction of Refractory Brickwork
Warning! Health hazard due to ceramic fiber material!
Sealing cords and fiber plates for sealing contain ceramic high-temperature mineralfibers, which may be a health hazard in the case of direct contact or if fiber dust isinhaled.
When handling sealing cords or fiber plates, wear appropriate protective clothing(to protect your throat and wrists, loosely fitting overalls, gloves, safety goggleswith side shields, FFP2 respirators).
Caution!
The heat generator is subject to thermal expansion. Therefore flexible connectorsmust be fitted between all fixed lines and ducts and the burner. When connectingthe flexible connectors, note the direction of the expansion.
Install the burner according to the following drawing using the installation materialincluded with the delivery.

Note
The fireproof material for the refractory brickwork must have an AL2O3 content of atleast 60% and a spalling resistance of at least 15.
Note
The angle of the opening in the refractory brickwork must be at least 60 .The burner head has to protrude by at least length Z beyond the refractorybrickwork into the furnace. It is best to use a burner with the standard head length.
Caution!
Use only the pre-manufactured boiler seal for the sealing to the boiler!
Wrap the gap between the burner head and the refractory brickwork with ceramicfiber material (e. g. Cerafelt).
Fasten the fiber material with wire.
Caution!
On no account must the gap be bricked.
Connecting Lines and Fittings
After mounting the burner, connect the lines and fittings intended for your plant tothe burner. The corresponding connection dimensions can be found in the chapterentitled "Dimensions / Types". A diagram of the lines already connected ex workscan be found at the end of this chapter.
More detailed information on the plant-specific arrangement of the burner, thefittings, the lines and the burner control system, as well as on the materials, whichyou must use, can be found in the plant drawing and in the circuit diagram in youroperator's manual.
In principle, you should comply with the following installation instructions:
