CUENOD Know-How

Some applications do not allow the Diamond head to be used to reduce the levels of NOx. For these particular cases, we have recourse to external injection of the combustion gases collected in their exhaust duct and powered into the flame by a turbine.

The reduction in NOx follows the same principle as that of the diamond head, through the reduction of flame temperature that it brings about.

The RGC® (combustion gas recirculation) system is a complete assembly that comprises a stainless steel fan and an injection spacer for the injection of the combustion gases into the flame. The flow of these gases is managed by a valve controlled by a servomotor or a recirculation fan turbine speed variator. The assembly is connected by insulated tubing.
