Riello has developed new RDB burners based on blue flame technology, designed to meet the most stringent standards for NOx emissions in oil-fired residential boilers.

The new models include RDB BG BLU, and RDB BX and BT Yellow/BLU, as well as two-stage variants on both model families. Riello’s two-stage operation system with suitable controls allows a significant increase in the overall efficiency of oil fired heating systems, along with reduced electrical consumption. This makes them the perfect solution for high efficiency residential boilers.

RDB BG BLU two-stage burners are suitable for use with kerosene and gasoil, utilising Riello’s new BG combustion head design for cleaner combustion. The combination of two-stage operation and low NOx emissions makes them ideal for condensing and combination oil boilers.

RDB BG BLU burners use a single motor to drive the coaxial fan and the pump, the latter delivering two stages of pressure. When using gasoil, they offer a turndown ratio of up to 1.5:1.

RDB BX BLU two-stage burners use a new BX combustion head to guarantee low NOx emissions in compliance with the ErP Ecodesign Directive. They are suitable for use with kerosene, using a specially designed kerosene pump, and also incorporate an advanced head-setting system.

All Riello RDB burners can be used in a balanced flue or conventional flue configuration and are designed for ease of installation and servicing.
