The proven low NOx burner with internal flue gas recirculation of type NAB (GO) convinces with low emission values. The internal flue gas recirculation of the NAB (GO) burner takes place independently in the area of the combustion chamber - without any other secondary equipment or additional measures. A flue gas recirculation flow takes place due to the specific design of a flue gas injector at the burner mouth. The associated recirculation flow in the combustion chamber onto the flame has a decisive influence on the level of NOx values.

The fuels used are either liquid and/or gaseous. The proven M&S low NOx nozzles are used on both the oil and gas side.
