What is the function of a cooling tower in a steam power plant?
Answer & step-by-step solution
A cooling tower rejects waste heat from the condenser cooling-water circuit to the atmosphere, lowering the water temperature so it can be recirculated through the condenser.
Concept & Reasoning
The condenser transfers heat from exhaust steam to circulating cooling water. The cooling tower then cools that warmed water mainly by evaporative heat and mass transfer. Thus the condenser and cooling tower form two distinct stages of heat rejection.
How to Solve It in the Exam
Condenser cools/condenses steam; cooling tower cools condenser water.
Important Exam Point
Track which fluid each component acts on.
Quick Trick
Condenser cools/condenses steam; cooling tower cools condenser water.
Common Mistake
Calling the cooling tower a device that directly condenses turbine exhaust steam.

उत्तर और चरणबद्ध हल
B — कंडेंसर से आने वाले पानी को ठंडा करना। कूलिंग टॉवर कंडेंसर शीतलन-जल परिपथ की अपशिष्ट ऊष्मा वायुमंडल में छोड़ता है, जिससे पानी का तापमान घटता है और उसे फिर से कंडेंसर में भेजा जा सकता है।

જવાબ અને પગલાવાર ઉકેલ
B — કન્ડેન્સરમાંથી આવતા પાણીને ઠંડું કરવું. કૂલિંગ ટાવર કન્ડેન્સર શીતલન-જળ પરિપથની કચરા ઉષ્મા વાતાવરણમાં છોડે છે, જેથી પાણીનું તાપમાન ઘટે અને તેને ફરી કન્ડેન્સરમાં મોકલી શકાય.
