Cooling Tower Spray Nozzle
Overview
The spray nozzle distributes hot water evenly across the fill or heat exchanger coils inside a cooling tower. Proper water distribution is essential for maximizing heat transfer and minimizing dry spots.
Function in Cooling Towers
Spray nozzles atomize or fan out water into fine droplets or sheets. This expands the water’s surface area, ensuring uniform evaporation when exposed to airflow.
Spray Patterns
- Full-cone: Round spray pattern; ideal for general-purpose coverage.
- Hollow-cone: Ring-shaped pattern; effective for light to medium loads.
- Flat-fan: Linear spray; used in rectangular tower designs.
Applications
Spray nozzles are used in open cooling towers, closed-circuit towers, and evaporative condensers. They maintain uniform water coverage, which prevents uneven cooling or hotspots.
How to Select
- Choose spray pattern based on tower geometry and distribution basin design.
- For high fouling water, select larger orifice nozzles to prevent clogging.
- Material choice depends on water chemistry: PP/PVC for standard water, stainless steel for high-pressure or corrosive fluids.
