What is the selection criteria of Natural Draught Cooling
Tower and Induced Draught Cooling Tower . Where we prefer
NDCT and where IDCT.
Answer Posted / suresh sarma
Major factors are :
1. type of Load:- NDCT need consistent load and are not very suitable for part load since the draft is a function of exit air temperature which is a function of hot water. hence mostly used in power plants.
2. NDCT need higher pumping head to provide a proper D/H ratio.
3. NDCT size becomes bigger in dry climate because of low RH. NDCT operate on principle of buoyancy or chimney effect and hence dry and hot weather are much less suitable for it and increase the required size and cost.
4. Time of construction is much more than an IDCT.
5. They are more suitable for larger Ranges and longer approaches.
6. Is generally a concrete structure and requires special equipment and manpower.
7. NDCT performance is directly badly effected by wind speed.
many other finer parameters are there. please read difference between NDCT and IDCT IN https://www.gtpl.co.in/files/Comparison%20between%20Natural%20Draft%20Cooling%20Tower%20and%20Induced%20Draft%20Cooling%20Tower.pdf
