Natural draft cooling towers - Import export

The natural draft cooling tower is the right choice for large power plants.It offers the following advantages :power saving (no power consumption to induce air flow- no fan).environmentally friendly.no mechanical noise (no fan).safety of operation.no recirculation as the plume is rejected at high level.limited plot area.limited maintenance.high longevity (generally more than plant life expectancy).Payback period between 8 and 16 years depending on several factors.Hamon offers both basin or water collecting devices. This last solution, developed by Hamon, is recommended for large cooling towers.It offers the following advantages :less pressure drop in the air inlet.reduction of pumping power.decrease of acoustic pressure in air inlet

The fan assisted natural draft cooling tower (FAND) combines the advantages of the natural draft cooling tower and the mechanical draft cooling tower.It becomes the best available technology when :Locations with limited plot plan. Overall height is limited. Important heat load . ADVANTAGES VS. CELLS: Compact arrangement. Power saving due to natural draft. No recirculation. Always a good alignment considering wind directions. Cooling by natural draft in case of electricity shortage.ADVANTAGES VS. NATURAL DRAFT CT: Reduced height. Better cooling characteristics during the summer season. Higher flexibility

Plume-abated fan assisted natural draft or circular hybrid cooling tower is the best technical solution for large heat loads and stringent plume abatement requirements.Seawater application. If overall height is limited. To keep countryside free from visible plume formations and shadow .For locations close to residential areas .To facilitate permission processes. ADVANTAGES VS CELL TYPE HYBRID COOLING TOWER: Compact arrangement/space saving. No recirculation and interference effects. No wash down (grounding) effects of plume. Use of natural draft. No corrosion due to humidity and salinity in the neighborhood. Visually an interesting architectural structure.

An indirect dry cooling system is characterized by the use of a condenser and air-cooled heat exchangers.The cooling system consists of the following main components :condenser (surface or spray type),cooling water circulating pumps and recovery turbines, if applicable,heat exchanger deltas including louvers,natural draft cooling tower,piping and valves,water storage tanks and transfer pumps,electrical equipment,instrumentation and control,accessories such as cleaning system, nitrogen blanketing system,The warm water from the condenser is delivered to the natural draft cooling tower by the cooling water circulating pumps and an underground piping network. After the cooling in the heat exchangers, the cold water returns to the condenser.
