Modulating Gas Burners RS 310 - 610/M MZ Series

The high power monoblock Burners Series RS 310-410-510-610/M MZ, are the result of intensive activities of
technical research and considerable investments, carried out in recent years, that allowed the highest levels of
technological development to be achieved in the Industrial Burners context, confirming the historical leadership
of Riello in this important area of energy management.
The remarkable results of performance, quality and reliability, are now consolidated by the creation of new
models in the 3-6 MW range, RS 310-410-510-610/M MZ, able to summarize and concentrate the best technological
expertise of Riello.
The RS 310-410-510-610/M MZ burners series covers a firing range from 1200 to 6250 kW, and it has been
designed for use in low or medium temperature hot water boilers, hot air or steam boilers, diathermic oil
boilers. Operation can be “two stage progressive” or, alternatively, “modulating” with the installation of a PID
logic regulation.
The exclusive design ensures reduced dimensions, simple use and maintenance.
A wide range of accessories guarantees elevated working flexibility.

Modulating Gas Burners RS 310 - 610/M MZ Series

GAS TRAINS

The burners are fitted with a butterfly valve to regulate the fuel, controlled by the main management module
of burner through a high precision servomotor.
Fuel can be supplied either from the right or left sides, on the basis of the application requirements.
A maximum gas pressure switch stops the burner in case of excess pressure in the fuel line.
The gas train can be selected to best fit system requirements depending on the fuel output and pressure in
the supply line.
The gas trains are with or without seal control.

Modulating Gas Burners RS 310 - 610/M MZ Series

Gas trains are approved by standard EN 676 together with the burner.
The overall dimensions of the gas train depends on how they are constructed. The following table shows the
maximum dimensions of the gas trains that can be fitted to RS 650-800-1000-1200/M MZ burners, intake and
outlet diameters and seal control if fitted.
The maximum gas pressure of gas train “MULTIBLOC” type is 360 mbar, and that one of gas train “COMPOSED”
type is 500 mbar.
“MULTIBLOC” guarantees a range of pressure towards the burner from 4 to 60 mbar. For version DN 65 and DN 80
is from 20 to 40 mbar. For version DN 100 is from 40 to 80 mbar. The range of pressure in the “MULTIBLOC” with
flange can be modified choosing the stabiliser spring (see gas train accessory).
The maximum gas pressure of gas train “CB” series is 500 mbar. “CB” gas train guarantees a range of pressure
towards the burner from 10 to 30 mbar. The range of pressure can be modified choosing the stabilizer spring
(see accessories).
The maximum gas pressure of gas train “DMV” series is 500 mbar. “DMV” gas train is supplied without pressure
governor.

Pressure Drop Diagram

The diagrams indicate the minimum pressure drop of the burners with the various gas trains that can be matched
with them; at the value of these pressure drop add the combustion chamber pressure.
The value thus calculated represents the minimum required input pressure to the gas train.

The minimum input gas pressure required is 15 mbar while burner operating.
In particular, the pressure difference between gas train upstream and downstream has to remain always over
pressure drop values indicated below.

Ventilation

The ventilation unit comes with a sound proofing system.

All the burners are fitted with fans, which give excellent performance and are fitted in line with the combustion
head. The air flow and sound-deadening materials used in the construction are designed to reduce sound
emissions to the minimum and guarantee high levels of performance in terms of output and air pressure.
A high precision servomotor through the main management module installed on each burner, controls the air
dampers position constantly.

New ventilation structure

A new ventilation structure has been developed in
order to reduce the overall dimensions and weight

Simplified Maintenance
for motor and fan by direct Air adjusting dampers
extraction through opening flange at air inlet side with ball bearings

Combustion Head

The combustion head adjustment system allows to adapt internal geometry of the head to the output of the
burner. This system guarantees excellent mix on all firing rates range as well as reducing noise and pollutants.

Operation

BURNER OPERATION MODE

The RS 310-410-510-610/M series of burners can have “two-stage progressive” or “modulating” operation.

Output regulator Analog 4-20 mA or 0 - 10V

converter for remote modulation

On “two-stage progressive” operation, the burner gradually adapts the output to the requested level, by varying
between two pre-set levels (see picture A).

On “modulating” operation, normally required in steam generators, in superheater boilers or diathermic oil
burners, a specific regulator and probes are required. These are supplied as accessories that must be ordered
separately. The burner can work for long periods at intermediate output levels (see picture B).

Modulating Gas Burners RS 310 - 610/M MZ Series

The RS 310-410-510-610/M MZ series burners are fitted with the LFL 1.333 or RMG88.62 C2 microprocessor control
panel for the supervision during intermittent operation. The FS2 burners are fitted with the LGK16.333A27 control
panel.
For helping the commissioning and maintenance work, on the RMG/M control box, there are two main elements:

RMG 88.62 C2

RMG 88 DIGITAL CONTROL BOX

Two main elements of the RMG/M control box make easy the commissioning and the maintenance:

The lock-out reset button is the central The multi-color LED is the central indication

control and for activating / deactivating diagnosis.

Both elements are located under the transparent cover of lock-out reset button, as shown in the picture above.

There are two diagnostic choices, for indication of

operation and diagnosis of fault cause:
