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.
