Low NOx burners

Riello has extended its RS-RL-RLS range of monobloc low NOx burners.

Outputs have been increased to 12MW following the introduction of models 1000 and 1200.

The new units build on the features of the R Series with advances in power output control and ventilation Suitable for gas, light oil or dual fuel application, advanced combustion technology ensures low NOx levels conforming to Class 3 EN 676.

The burners come in various control configurations. These include modulating operation using an electronic cam for closer and more repeatable control of the air-fuel ratio, and options for variable speed drive of the combustion air fan motor to reduce energy consumption and noise levels. Integration of O2 trim control ensures combustion efficiency is maintained throughout the modulation range.
