SALIENT TECHNICAL FEATURES
Four (4) numbers Main cooling towers have been already provided by employer in
Rihand Super Thermal Power Project Stage-III (2x500 MW) for condenser and unit
auxiliary cooling water purpose. As the achieved cold water temperature is higher than
design cold water temperature it is proposed to modify/augment the existing one
cooling tower to achieve the design cold water temperature.
The scope includes Design, Engineering, Manufacture, Supply, Construction, Erection,
Testing & Commissioning works for Augmentation/Modification of existing one Induced
draft Cooling Tower and associated equipment’s for Rihand Super Thermal Power
Project-stage-III (2 X 500 MW).
The Technical features of the Existing Cooling Towers are as follows:-
Type of existing cooling tower
Induced Draft RCC cooling Tower,
Double Inlet Type
Number of existing Cooling Towers
4 (Four) numbers
(One no for Augmentation/
Modification in this package)
9 (Nine) numbers (8W+1S)
30,000 Cu.M/hr
Number of total cells per Cooling Tower
