Technical characteristics of low NOX pulverized coal burner:

Gas polymorphism and high efficiency mixing principle:

The rotating airflow or high-speed airflow in the pre combustion chamber prechamber formed intense heat recirculation zone ignite the precombustion chamber of the pulverized coal air flow, main combustion chamber burner of pulverized coal flow stable ignition and combustion can provide sufficient heat source.

Flame stabilization principle:

At the outlet of the burner air nozzle, set a non streamline shaped objects, bluff body, make the air flow around. In the wake region of a blunt body have a return, the high temperature flue gas entrainment, to favor fuel ignition and flame stability.

Bias combustion principle:

The centrifugal inertial force or other means will be primary air pulverized coal flow into powder flow and powder poor rich two streams flow, respectively by different nozzle into the furnace to achieve bias combustion.

Excellent low load stable combustion capability, low NOx combustion emission characteristics

The excellent characteristics of efficient pulverized coal combustion, slagging and high temperature corrosion prevention

The separation of SOAF overfire air also has reduced the deviation of the furnace outlet temperature characteristics better.
