RDB/M - MK - THE NEW CONCEPT OF MODULATING BURNER
LOW NOx MODULATING LIGHT OIL BURNERS
Riello includes the modulation version in the well-known and appreciated RBD range. Riello is able to propose
an innovative an patented solution of modulating burner with pump and fan matched on the same shaft, modifying the good ventilation structure of the RDB 2.2 model and introducing a modified pump for higher pressures.
RDB MK is the Riello proposal with a modulation ratio up to 1 : 2.5 (according to the required configuration), outputs between 8 and 30 kW, lower NOx emissions, completely integrated to meet the new strictest requirements
of the ErPD norm.
The complete operation is managed by a digital control box, able to allow the use of an UV flame management
system. The performance of RDB are controlled by an inverter connected to a small motor which changes the fuel
supply according to the required output. The settings are carried out through an extractible LCD display which
allows the burner setting wherever it is placed. As accessory, Riello has equipped the burner with a device for
the remote burner control.
ADVANTAGES AT A GLANCE
•Modulation up to 1 : 2.5 with minimum output at 8 kW
•High ventilation performance
•Low emissions
•Noise reduction
•Low electrical consumptions thanks to a small motor at low voltage
•Pump for high pressures up to 30 bar
•Modulating operation in CF and BF configuration

kW, in three different structures. The models are available in light oil and kerosene versions, conventional flue
and balanced flue, with or without the fuel pre-heater fitted.
These models are distinguished by their compact size. All the models use the same components designed by
Riello for the RDB series. The high quality level guarantees safe working. The RDB burners are equipped with a
geared pump suitable for Kerosene, Low Sulphur Kerosene and ultra low sulphur diesel oil (ULSD).

RDB/D - BX – THE NEW MODELS FOR TWO STAGE
OPERATION
LOW NOx TWO STAGE LIGHT OIL AND KEROSENE BURNERS
The attention of Riello to each market requirement, exceed all expectations. Based on the natural evolution of
the RDB series,Riello has invested all his experience in creating a two stage burner, with the aim to complete the
range and meet the strictest requirements of the ErPD norm.
This product has been developed keeping the good ventilation structure of the RDB2.2 and 3.2 models, modifying
the pump and the control box. The new two stage RDB burner meets the requirements of the new European
standards in order to create a burner with the same qualities of the previous two stage burner models.
Moreover Riello has provided the most advanced technical solutions to this project in order to guarantee lowest
NOx and noise emissions, as the GK LOW NOx combustion head, designed completely by Riello, meets the requirements of the EN 267 standard; anyway it is available a “on-demand” solution with standard combustion head.
The project has been completed, providing the balanced flue “BF” and conventional flue “CF” version, both
equipped with a digital control box.

RX - PREMIX GAS BURNERS
RX PREMIX GAS BURNERS FOR HEATING AND LIGHT INDUSTRIAL PROCESSES
The Premix gas burners are especially suitable for heating and light industrial processes, requiring the burner
integration to achieve very compact size. The Premix competitive features are the high modulating ratio (up to
1 : 7) and lower sound emissions than diffusive burners.
Riello RX premix series is the ideal solution for heating applications using condensing boilers, air conditioning
using absorption chillers, light industrial processes for bakery ovens, spray paint booths, air heaters, grain
dryers and textile applications.
RX burners reach values of CO and NOx emissions lower than the more restrictive European Standards.
The premix burner combustion heads can be designed in order to provide a cylindrical or frontal flame shape,
and it is characterised by a "seamless knitted wire" (Riello patented) free of welded seams, in order to avoid
possible damages due to thermal stress.
Two series of premix burners are available:
• a range from 4 to 1080 kW, with one stage, two stage fully modulating operation, with a variable speed drive
motor, gas train integrated in the burner, and air-gas mixing in the fan suction line circuit. Operation with
an electrical supply of 1/230V/50-60Hz up to 850kW and 3/400V/50Hz for 1080kW;
• a range from 55 to 730 kW, with progressive two stage or modulating operation, air-gas mixing in the
combustion head suction line circuit, and gas train supplied separately. Operation with an electrical supply
of 1/230V/50Hz or 3/400V/50Hz.
All RX burners can be suitable for LPG combustion.
ADVANTAGES AT A GLANCE
•Complete range of burners from 5 to 1000 kW, with excellent turn-down modulation ratio (up to 1 : 7)
•Ideal solutions both for condensing applications, absorption chillers and light industrial process
•Compact flame geometry allowing reduction of combustion chamber dimensions
•Thermal exchange increasing from irradiation particularly at minimum output
•Combustion head with fibre manufactured in seamless knitted wire: removal of any critical situation caused
by thermal stress
•High combustion intensity with reduced combustion head dimension very low noise emissions: the < 30% vs
equivalent jet burner
•Values of CO and NOx emissions lower than the more restrictive European Standards
•Available for North American market too

Selection field
The models of RS-RLS are excellently covering the 10 – 20 MW power range, providing the ideal solution for
matching to Heating Boilers, Steam Generators and Industrial Process Plants.
An unmistakable design and style, utilizing high technology solutions and high levels of industrialization, distinguish the R Series product from the competition in today’s market.
Since the beginning of his industrial development, Riello has looked for a relationship between Industry and
Style in order to help maintain the reputation of Italian design on the world stage.
Once again the New R Series preserves the marriage between Performance and Design, giving the product range
an unmistakable Style.
The new models design is Patented for protection from copies and imitation (Patents N.1312904 - N.1314561 - N.
1314553).

ER SERIES - INDUSTRIAL OIL, GAS AND DUAL FUEL AIR
REGISTER BURNERS
The industrial burners ER series are designed especially for water tube boilers used in big heating installations
and industrial processes with a remarkable thermal demand.
These burners allow to realize a modular and flexible combustion system adding a preparation fuel unit
(regulation pressure group set, preheating/pumping oil station), a gas train, a control panel and a fan.
Preheated air can also be used as in the oil diathermic generators and other heat recovery systems.
The modulating load control always allows to reach a wide turndown ratio and optimal fluid-dynamics
conditions for a good combustion.
FEATURES AND ADVANTAGES
•High flexibility on configuration with mechanical or electronic cam versions and natural gas, gas oil or dual
fuel gas/gas oil versions
•Great ease of access and maintenance
•Combustion head capable of axial or
continuous radial adjustment, depending on specific application
needs
•Independent primary and secondary air control over full operating range

ER 20 SE - OVERVIEW
The new ER 20 SE burner provides total control of secondary combustion air thanks to a mechanical system
with a variable register. This way, the burner can be adapted to the furnaces of water pipe boilers in
applications with a single or multiple burners in a single combustion chamber.
The combustion head features optimised internal geometry to reduce load loss and the power demand of
fan motor.
Radial adjustment for head gas pipes makes to optimal combustion.
The burner meets the requirements of EN 676, Class 2

DB SERIES - INDUSTRIAL DUAL BLOCK OIL, GAS, AND DUAL
FUEL LOW NOX AND YELLOW FLAME BURNERS
The DB burners are dual block burners for application in big plants (district heating, hospitals) as well as in
food, chemicals, textile industry for matching with hot water boilers, steam and thermal oil generators.
The DB burners can be supplied with electronic or mechanical air-fuel ratio control according to customer
specification.
The DB burners can work with pre-heated air up to 150°C as standard, up to 250°C with special construction.
New variable geometry combustion head allows to reach < 80 mg/kWh NOx emission on natural gas operations.
As part of the offer, various accessories (air fan, control panels, high pressure gas train, etc) are available.
