BYPASS VALVE WITH ATOMIZING NOZZLE INCORPORATED IN THE PRESSURE REDUCING STAGE AT THE VALVE OUTLET :

This design incorporates the atomizing nozzle in the Pressure Reducing Stage (Silencer) at the valve outlet. The Laval nozzle is not of a straight type but a ring nozzle which creates a circular laval jet. The spray water is catered through passages in the pressure reducing plate and injected into the laval ring nozzle. This highly efficient design eliminates the need of atomizing steam valve and steam atomizing lines.

ADVANTAGES :

High turndown ratio of 25:1

Excellent Temperature control as close as 3 - 4 deg.C. above saturation.

Short straight outlet line required, even at low steam velocities.

No additional piping for atomizing steam.

Eliminates separate steam atomizing valve.

Instant absorption of water particles owing to high mechanical energy of atomizing steam.
