RDB/M - MK - THE NEW CONCEPT OF MODULATING BURNER

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, mo-difying the good ventilation structure of the RDB 2.2 model and introducing a modified pump for higher pres-sures.RDB MK is the Riello proposal with a modulation ratio up to 1 : 2.5 (according to the required configuration), ou-tputs 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.

LOW NOx MODULATING LIGHT OIL BURNERS

• 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• New digital control box with UV flame management system

The Riello RDB series of one stage light oil and kerosene burners is available with an output ranging from 17 to 120 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).The project has been completed, providing the balanced flue “BF” and conventional flue “CF” version, both equipped with a digital control box.

RDB/D - BX – THE NEW MODELS FOR TWO STAGE OPERATION

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 requi-rements 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.

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.

RLS 200/EV - OVERVIEW

The standard RLS/E-EV burners are equipped with Siemens LMV 26 and, on demand, with Lamtec BT 340 system.

DIGITAL BURNER MANAGEMENT SYSTEM

The BT340 Digital Burner Management System is a microprocessor-based device designed for the control and supervision of Dual Fuel forced draft burners. It includes the standard function of a Flame Safeguard and in the meantime controls the air-fuel mixing. The actuators, connected to the air damper and to the Gas and Oil Regulators, without clearance and mechanical hysteresis, are stepper motors with high accuracy positioning. The modulating operation with both managed fuels, Gas and Oil, is obtained by an additional load control module. The burner power management, performed through this expansion module, which operates in connection with the relevant temperature/pressure probes. The inverter management system is performed through a dedicated module (and the relevant motor speed sensor for the feedback). The UI300 customer interface display represents the operating unit to interface the system.

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
