વરાળ વીજ મથકમાં કન્ડેન્સરનો હેતુ શું છે?
જવાબ અને પગલાવાર ઉકેલ
A — વરાળને પાછી પાણીમાં ફેરવવી. કન્ડેન્સર ટર્બાઇન એક્ઝોસ્ટ વરાળમાંથી ગુપ્ત ઉષ્મા દૂર કરી તેને કન્ડેન્સેટમાં ફેરવે છે અને નીચું એક્ઝોસ્ટ દબાણ જાળવે છે, જેથી ટર્બાઇનનું કાર્ય આઉટપુટ વધે છે.

Concept & Reasoning
Condensing exhaust steam closes the Rankine water-steam cycle so condensate can be pumped back to the boiler. A good condenser also creates vacuum/low back pressure at the turbine exhaust and facilitates recovery of high-quality feedwater.
How to Solve It in the Exam
Condenser: steam back to water + low turbine back pressure.
Important Exam Point
Cooling water removes heat from steam; it does not mix with condensate in a surface condenser.
Quick Trick
Condenser: steam back to water + low turbine back pressure.
Common Mistake
Confusing condenser with cooling tower—the cooling tower cools circulating cooling water.
What is the purpose of a condenser in a steam power plant?
Answer & step-by-step solution
The condenser removes latent heat from turbine exhaust steam and converts it back into water (condensate), while maintaining a low exhaust pressure that improves turbine work output.

भाप विद्युत संयंत्र में कंडेंसर का उद्देश्य क्या है?
उत्तर और चरणबद्ध हल
A — भाप को वापस पानी में बदलना। कंडेंसर टरबाइन निकास भाप से गुप्त ऊष्मा हटाकर उसे कंडेनसेट में बदलता है और कम निकास दबाव बनाए रखता है, जिससे टरबाइन का कार्य आउटपुट बढ़ता है।
