VINDHYACHAL STPP STAGE-IV (2 X 500 MW)

Augmentation/Modification Works of One Cooling Tower Package

Three (3) Nos Main cooling towers are already been provided by employer in VSTPP STAGE-IV

for condenser and unit auxiliary cooling water purposes. As the achieved cold water temperature

from cooling tower is higher than the design cold water temperature by around 5 Deg C, it is

proposed to modify/augment one number of existing cooling tower to achieve the design cold water

temperature.

The scope includes Design, Engineering, Manufacture, Supply, Construction, Erection, Testing &

Commissioning works for Modification/ Augmentation of one existing Induced draft Cooling

Towers and associated equipment’s for Vindhyachal Super Thermal Power Project-stage-IV (2 X

500 MW).

The Technical features of the Existing Cooling Towers are as follows:-

a) Type of existing cooling tower Induced Draft RCC cooling Tower,

Single Inlet Type

b) Number of existing Cooling Towers 3 (Three) numbers

c) Number of total cells per Cooling Tower 18 (Eighteen) numbers (16W+2S)

d) Design flow for each Cooling tower 40,000 Cu.M/hr

e) Range of Cooling 10.5 deg. C.

f) Design Cold Water temperature 32.5 deg C.

g) Design ambient wet bulb temperature 27.4 deg C.
