Riello 40 G3 Light Oil Burner

The Riello 40 G3 is a light oil burner in the Riello programme, rated about 30-66 kW (light oil) for small steam boilers and unit heaters. The Riello 40 G3 is the light-oil member of the 40 series, aimed at small and mid-size steam and hot-water boilers that need a compact single-stage head. Its fixed single-stage firing keeps the control simple, which is why plant engineers keep it for straightforward light-oil replacement jobs. It is the light-oil entry model of the 40 family, often chosen for straightforward diesel replacement where a fixed single stage is enough.

Applications

Riello 40 G3 is specified for small steam boilers and unit heaters where light oil burner duty must stay stable across load swings.

Plants also fit the 40 G3 to packaged hot-water boilers in light-oil plants, because its single-stage control keeps commissioning simple.

For light-oil replacement jobs on existing 40-series throats, the 40 G3 is the Riello option that Because it shares the 40-series flange, the 40 G3 is the natural light-oil swap where a 40-series burner already occupies the boiler throat.

The 40-series head carries no modulation, which keeps the fuel-train and control simple for small boiler rooms.
