Natural Draft Counter Flow Cooling Tower
Natural draft (or ‘draught’) cooling towers operate on the principle that hot air rises, this is known as the ‘stack effect’.
Wet natural draft cooling towers are used primarily for the power industry due to the large cooling capacity demands. Natural draft cooling towers are capable of cooling large volumes of water for prolonged periods of time without any service interruption.
This type of tower is usually constructed from metal and reinforced concrete.
- Low maintenance costs.
- Low operational costs.
- Low system losses (typically less than 1% of total flow).
- Low noise level as there are no fans used.
- Large cooling capacity.
- Large initial capital investment.
- Difficult sometimes to get planning permission due to the large structure and aesthetic affect upon the local area.
This 3D model shows all major components associated with a typical natural draft cooling tower, these include:
- Hyperboloid Concrete Tower
- Fill (Heat Exchanger)
- Spray Nozzles
- Exhaust Gas Stack
