RIELLO 40 N SERIES |
|
| |
The Riello 40 N series of one stage heavy oil burners, is a complete range of products developed to respond to any request for the use of heavy oil in heating systems and light industrial processes. The Riello 40 N series is available in two different models, with an output ranging from 34 to 217 kW, divided into two basic structures.
All the models use many components designed by Riello for the Riello 40 series but are fi tted with special components for heavy oil combustion.The high quality level guarantees safe working.
In developing these burners, special attention has been paid to reducing noise, to the ease of installation and adjustment, to reducing the size in order to facilitate installation in any kind of boiler on the market. All the models are conform to EMC European Directives, for Low Voltage and Machinery. All the Riello 40 N burners are tested before leaving the factory. |

Two Stage Heavy Oil Burners PRESS N SERIES |
| |
 |
The PRESS N series of burners covers a fi ring range from 171 to 1140 kW and they have been designed for use in civil installations of average dimensions, like building areas and large apartment groups or for use in industrial applications, like small or medium plants.
Operation is two stage; a servomotor adjust automatically air damper opening, to obtain the right air delivery on both stage. The burners are fi tted with a microprocessor control panel which supplies indication of operation and diagnosis of fault cause.
The combustion head, that can be set on the basis of required output, allows optimal performance ensuring good combustion and reducing fuel consumption and is available in two different length to be selected on the basis of specifi c application requirements.
In basic version the burners are supplied for use with heavy oil 7°E viscosity, but they can be supplied with higher viscosity oil with a specifi c heaters kit. Simplifi ed maintenance is achieved by the slide bar system, which allows easy access to all of the essential components of the combustion head.

Two Stage Heavy Oil Burners PRESS N/ECO SERIES |
|
| |
PRESS N/ECO burner series covers a firing range from 171 to 1140 kW and it has been designed for operation with low sulphur fuels. The burners are equipped with a separate low speed pump.
They have been designed for use in civil installations of average dimensions, like building areas and large apartment groups or for use in industrial applications, like small or medium plants. Operation is two stage; a servomotor adjust automatically air damper opening, to obtain the right air delivery on both stage. The burners are fi tted with a microprocessor control panel which supplies indication of operation and diagnosis of fault cause. The combustion head, that can be set on the basis of required output, allows optimal performance ensuring good combustion and reducing fuel consumption and is available in two different length to be selected on the basis of specifi c application requirements.
As standard the burners are supplied with electrical heaters installed on crucial parts of hydraulics circuit, for use with heavy oil viscosity up to 20°E. Simplified maintenance is achieved by the slide bar system, which allows easy access to all of the essential components of the combustion head. |

Three Stage Heavy Oil Burners PRESS T/N - T/N ECO SERIES |
| |
 |
The PRESS T/N series of burners covers a fi ring range from 800 to 5130 kW. They have been designed in three versions for use in commercial and industrial installations, to burn different oil viscosity from 7 up to 60 °E @ 50°C. Operation is three-stage, thus making these burners suitable for installations that have variable but predictable heating requirments.
A servomotor adjusts automatically air damper to the opening value, determined to obtain always the necessary fuel consumption. Every model of PRESS T/N series is available in two different combustion head lenght (short or long head) to be selected on the basis of specifi c application requirments. An electric preheater has been fi tted to maintain the oil at the correct atomising temperature at maximum ouput and special heaters kits are separately supplied for burning high viscosity oil. Simplifi ed maintenance is achieved by the Riello designed slide bar system, which allows easy access to all of the essential components of the combustion head.

Modulating Heavy Oil Burners PRESS P/N - P/N ECO SERIES |
|
| |
The PRESS P/N series of burners covers a firing range from 800 to 5130 kW. They have been designed in three versions for use in commercial and industrial installation, to burn different oil viscosity from 7 up to 60°E @ 50°C. Operation can be “two stage progressive” or, alternatively,
“modulating” with the installation of a PID logic regulator and respective probes, which guarantees a turn down ratio of 3:1.
The versatility of this range makes the burner well suited for use on steam boilers where the load factor is subject to wide variations, on thermal oil boilers and on boilers for particular heating plants, as hospitals or similar.
Simplified maintenance is achieved by the Riello designed slide bar system, which allows easy access to all of the essential components of the combustion head.

Modulating Heavy Oil Burners with Air/Steam Atomizing PRESS P/NA - P/NA ECO SERIES |
| |
 |
Heavy oil burner series P/NA is an evolution of the traditional heavy oil modulating burners P/N series.
The new range applies a different technology to replace the usual mechanical atomising (high pressure) by “assisted” air/ steam atomising (feed pressure 5-8 bar) and taking the related
advantages when burning heavy fuels (even vegetal oil).
The upgraded design has been introduced to meet even the worst fuel qualities and to reach anyway the best achievable combustion performance (lower particulate and NOx emissions).
The capacity range is suited to cover applications on steam generators designed for production from 1 to 6 tons/hr of steam or an equivalent capacity in case of other kind of boiler. Reliable and smooth ignition is achieved by LPG pilot burner installed into the combustion head.
The control system includes all safety and operation interlocks, making possible the confi guration compliance to the latest design norms on world-wide base (i.e. EN 267 – UL 296 – others), by the available options on request.
