The RS burners series covers a firing range from 81 to 2290 kW, and it has been designedfor use in hot or superheater water boilers, hot air or steam generators, diathermic oilboilers.Operation is "two stage progressive"; the burners are fitted with a microprocessor controlpanel which supplies indication of operation and diagnosis of fault cause.Optimisation of sound emissions is guaranteed by the use of fans with reverse curveblades and sound deadening material incorporated in the air suction circuit.The elevated performance of the fans and combustion head, guarantee flexibility of useand excellent working at all firing rates.The exclusive design ensures reduced dimensions, simple use and maintenance. A widerange of accessories guarantees elevated working flexibility.

The burners are fitted with a butterfly valve to regulate the fueldelivery on 1st and 2nd stage, controlled by a variable profilecam servomotor.

Fuel can be supplied either from the right orleft hand sides.

The gas train can be selected to best fit systemrequirements depending on the fuel outputand pressure in the supply line.The gas train can be “Multibloc“ type(containing the main components in a singleunit) or “Composed” type (assembly of thesingle components).

Please contact the Riello Burner Technical Office for different pressure levels from thoseabove indicated and refer to the technical manual for the correct choice of the spring.

In LPG plants, Multibloc gas trains do not operate below 0°'a1C. They are only suitable forgaseous LPG (liquid hydrocarbons destroy the seal materials).

MBC 1200 gas train: the minimum operating pressure (*) is higher or equal to 10 mbar. The gastrain has to be installed next to the burner (if needed, only with the adapters listed in thecatalogue) and it has to operate in its own working field.

MBC 1900-3100 gas train: the minimum operating pressure (*) is higher or equal to 15 mbar.The gas train has to be installed next to the burner (if needed, with the adapters listed in thecatalogue) and it has to operate in its own working field.

(*) it is the upstream gas train pressure in full load operation conditions.

Figure A

The following diagram enables pressure drop in a pre-existing gas line to be calculated and to select thecorrect gas train.The diagram can also be used to select a new gas line when fuel output and pipe length are known. Thepipe diameter is selected on the basis of the desired pressure drop. The diagram uses methane gas asreference; if another gas is used, conversion coefficient and a simple formula (on the diagram) transformthe gas output to a methane equivalent (refer to figure A). Please note that the gas train dimensions musttake into account the back pressure of the combustion chamber during operations.

Control of the pressure drop in an existing gas line or selecting a new gas supply line.The methane output equivalent is determined by the formula fig. A on the diagram and the conversioncoefficient.

Once the equivalent output has been determined on the delivery scale ( ), shown at the top of thediagram, move vertically downwards until you cross the line that represents the pipe diameter; at thispoint, move horizontally to the left until you meet the line that represents the pipe length.Once this point is established you can verify, by moving vertically downwards, the pipe pressure dropof on the botton scale below (mbar).By subtracting this value from the pressure measured on the gas meter, the correct pressure value willbe found for the choice of gas train.

Example: - gas used G25- gas output 9.51 mc/h- pressure at the gas meter 20 mbar- gas line length 15 m- conversion coefficient 0.62 (see figure A)

- equivalent methane output = 9.51 = 15.34 mc/h0.62

- once the value of 15.34 has been identified on the output scale ( ), moving vertically downwards youcross the line that represents 1" 1/4 (the chosen diameter for the piping);

- from this point, move horizontally to the left until you meet the line that represents the length of 15 mof the piping;

- move vertically downwards to determine a value of 1.4 mbar in the pressure drop botton scale;- subtract the determined pressure drop from the meter pressure, the correct pressure level will be found

for the choice of gas train;

- correct pressure = ( 20-1.4 ) = 18.6 mbar

Different lengths of the combustion head can be chosen for theRS series of burners.

The choice depends on the thickness of thefront panel and the type of boiler.

Depending on the type of generator, check that thepenetration of the head into the combustion chamber iscorrect.

The internal positioning of the combustion head can easilybe adjusted to the maximum defined output by adjustinga screw fixed to the flange.

The ventilation circuit produces low noise levels with highperformance pressure and air output, inspite of the compact

dimensions.

Except for the RS 190 model, the use of reversecurve blades and sound-proofing material keeps noise level verylow. In the RS 190 model, noise has been reduced by the specialdesign of the air suction circuit.

A variable profile cam connects the fuel and air regulations, toobtain a perfect control of combustion during the change ofstage. When the burner is not operating the servomotor closescompletely the air damper to reduce heat dispersion from theboiler.A minimum air pressure switch stops the burner when there isan insufficient quantity of air at the combustion head.

ADJUSTMENT

BURNER OPERATION MODE

On “two stage” operation, the burnergradually adapts the output to therequested level, by varying betweentwo pre-set levels (see picture A).

All RS series burners are fitted with a new microprocessor control panel for the supervision duringintermittent operation.For helping the commissioning and maintenance work, there are two main elements:

The lock-out reset button is the central operating element for resetting the burner controland for activating / deactivating the diagnostic functions.

The multi-color LED is the central indication element for visual diagnosis and interfacediagnosis.

Both elements are located under the transparent cover of lock-out reset button, as showed below.

There are two diagnostic choices, for indication of operation and diagnosis of fault cause:

- visual diagnosis :

- interface diagnosis : by the interface adapterand a PC with dedicateds o f t w a r e o r b y apredisposed flue gasanalyzer (see paragraphaccessories).

INSTALLATION DESCRIPTION

All the burners have slide bars, for easier installationand maintenance.

After drilling the boilerplate, using the supplied gasketas a template, dismantle the blast tube from the burnerand fix it to the boiler.

Adjust the combustion head.

Fit the gas train, choosing this on the basis of themaximum output of the boiler and considering theenclosed diagrams.

Refit the burner casing to the slide bars.

Close the burner, sliding it up to the flange.

Make the electrical connections to the boiler followingthe wiring diagrams included in the instructionhandbook.

Turn the motor to check rotation direction (if it is athree-phase motor).

Perform a first ignition calibration on the gas train.

On start up, check:- Gas pressure at the combustion head (to max. and

min. output)- Combustion quality, in terms of unburned substances

and excess air.

Installation, start up and maintenance must be carriedout by qualified and skilled personnel.All operations must be performed in accordance with thetechnical handbook supplied with the burner.

DIMENSIONING OF THE FUEL SUPPLY LINES

The fuel feed must be completed with the safety devices required by the local norms.

The table shows the choice of piping diameter for the various burners, depending on the differencein height between the burner and the tank and their distance.

With ring distribution oil systems, the feasible drawings and dimensioning are the responsibilityof specialised engineering studios, who must check compatibility with the requirements andfeatures of each single installation.

COMBUSTION HEAD

VENTILATION

The ventilation circuit produces low noise levels with highperformance pressure and air output, inspite of the compact dimensions.

Except for the RL 190 model, the use ofreverse curve blades and sound proofing material keepsnoise level very low.

In the RL 190 model, sound has been reduced by thespecial design of the air suction circuit.

An hydraulic ram allows to have a right air flow in anyoperational moment and the closure of the air damperwith burner in stand-by.

Different lengths of the combustion head can be chosen for theRL series of burners.

The choice depends on the thickness ofthe front panel and the type of boiler.

Depending on the type of generator, check that thepenetration of the head into the combustion chamber iscorrect.

The internal position of the combustion head can easilybe adjusted to the maximum defined output by adjustinga screw fixed to the flange.

ADJUSTMENT

All RL series burners are fitted with a new microprocessor control panel for the supervision duringintermittent operation.For helping the commissioning and maintenance work, there are two main elements:

The lock-out reset button is the central operating element for resetting the burner controland for activating / deactivating the diagnostic functions.

The multi-color LED is the central indication element for visual diagnosis and interfacediagnosis.

Both elements are located under the transparent cover of lock-out reset button, as showed below.

There are two diagnostic choices, for indication of operation and diagnosis of fault cause:- visual diagnosis :

- interface diagnosis : by the interface adapterand a PC with dedicateds o f t w a r e o r b y apredisposed flue gasanalyzer (see paragraphaccessories).

A modulation ratio of 2:1 is reached, thanks to the “two nozzles”technique; the air is adapted to the hydraulic ram positions.On “two stage” operation, the burner gradually adjusts outputto the requested level, by varying between the two pre-set levels(see figure A).

Nozzles

The nozzles must be ordered separately. The following table shows the features and codes on thebasis of the maximum required fuel output.

INSTALLATION DESCRIPTION

All the burners have slide bars, for easier installationand maintenance.

After drilling the boilerplate, using the supplied gasketas a template, dismantle the blast tube from the burnerand fix it to the boiler.

Adjust the combustion head.

Refit the burner casing to the slide bars.

Install the nozzle, choosing this on the basis of themaximum boiler output and following the diagramsincluded in the burner instruction handbook.

Check the position of the electrodes.

Close the burner, sliding it up to the flange, keepingit slightly raised to avoid the flame stability diskrubbing against the blast tube.

The burners are supplied for connection to two pipesfuel supply system.

Connect the ends of the flexible pipes to the suctionand return pipework using the supplied nipples.

Make the electrical connections to the burner followingthe wiring diagrams included in the instructionhandbook.

Prime the pump by turning the motor.

On start up, check:- Pressure pump (to max. and min.)- Combustion quality, in terms of unburned substances and excess air.

Installation, start up and maintenance must be carried outby qualified and skilled personnel.All operations must be performed in accordance with thetechnical handbook supplied with the burner.

Nozzles

The nozzles must be ordered separately. The following table shows the features and codes on thebasis of the maximum required fuel output.

ADJUSTMENT

All RL series burners are fitted with a new microprocessor control panel for the supervision duringintermittent operation.For helping the commissioning and maintenance work, there are two main elements:

The lock-out reset button is the central operating element for resetting the burner controland for activating / deactivating the diagnostic functions.

The multi-color LED is the central indication element for visual diagnosis and interfacediagnosis.

Both elements are located under the transparent cover of lock-out reset button, as showed below.

There are two diagnostic choices, for indication of operation and diagnosis of fault cause:- visual diagnosis :

- interface diagnosis : by the interface adapterand a PC with dedicateds o f t w a r e o r b y apredisposed flue gasanalyzer (see paragraphaccessories).

A modulation ratio of 2:1 is reached, thanks to the “two nozzles”technique; the air is adapted to the hydraulic ram positions.On “two stage” operation, the burner gradually adjusts outputto the requested level, by varying between the two pre-set levels(see figure A).

With single pipe systems, you can find air in the oil sucked by the pump that comes from the oil itselfdue to negative pressure or to a faulty seal.To solve this problem, we recommend fitting a degasing unit near the burner. Two versions areavailable with or without filter:

COMBUSTION HEAD

VENTILATION

The ventilation circuit produces low noise levels with highperformance pressure and air output, inspite of the compact dimensions.

Except for the RL 190 model, the use ofreverse curve blades and sound proofing material keepsnoise level very low.

In the RL 190 model, sound has been reduced by thespecial design of the air suction circuit.

An hydraulic ram allows to have a right air flow in anyoperational moment and the closure of the air damperwith burner in stand-by.

Different lengths of the combustion head can be chosen for theRL series of burners.

The choice depends on the thickness ofthe front panel and the type of boiler.

Depending on the type of generator, check that thepenetration of the head into the combustion chamber iscorrect.

The internal position of the combustion head can easilybe adjusted to the maximum defined output by adjustinga screw fixed to the flange.

DIMENSIONING OF THE FUEL SUPPLY LINES

The fuel feed must be completed with the safety devices required by the local norms.

The table shows the choice of piping diameter for the various burners, depending on the differencein height between the burner and the tank and their distance.

With ring distribution oil systems, the feasible drawings and dimensioning are the responsibilityof specialised engineering studios, who must check compatibility with the requirements andfeatures of each single installation.
