Solving the concerns rising from the usage of a fully wet
or a fully dry systems, a hybrid system provides more
efficient, more economical and environmental cooling
solution.
To propose hybrid layouts considering suffecient supply of fresh
ambient air to cooling towers, land usage, system performance
and feasibility.
To design a hybrid cooling system in a series configuration
with the dry section leading to handle nuclear power plant
steam condenser heat duty of 2900MW.
To maximize the heat duty handled by the dry cooling system
in order to reduce water evaporation versus all-wet system.
Water evaporation reduction through: Layout selection through:
The Hybrid cooling system results in about 26.9 % reduction in
water consumption compared to 100% wet cooling system under
given ambient conditions.
A hybrid cooling layout that combines dry and wet cells was
arranged into four circular units to minimize interference
and recirculation while ensuring equal air flow into each cell.
