Benefits & Purpose of a STORM™ Design Rotating Throat and Deflector

- Reduced or eliminated coal rejects, improved vectoring for improved grinding and improved pimary airflow controllability.

- Increased pulverizer & furnace residence time.

- Improved coal fineness.

- Capability to reduce air/fuel ratios.

- Reduced FEGT’s with improved combustion lower in the furnace.

- Reduced available “free” oxygen in the high temperature flame core.

- Excessive amounts of primary airflow tend to force ignition points away from the burner as a result of higher burner nozzle velocities, thus allowing infusion of oxygen “rich” air into the flame core and increasing NOx exponentially.

- Reduce pulverizer vibration & rumbling.

- Deflector sets an open area to maintain an acceptable velocity to keep coal particles in suspension and prevent coal spillage.
