Question 12Steam Plants - Assistant Engineer
70% to passA basic comparison can be made between a low-pressure evaporator operation and a main condenser with regards to the removal of non-condensable gases. The vacuum drag line for the main condenser is specifically connected in which area?
Amain tube bank
Bsteam lane
Chotwell
Dair cooler section
AI Explanation
The correct answer is D) air cooler section. The vacuum drag line for the main condenser is specifically connected to the air cooler section. This is because the air cooler section is where non-condensable gases, such as air, are removed from the main condenser. The vacuum drag line helps to draw these non-condensable gases out of the condenser, preventing them from building up and reducing the overall efficiency of the system. The other options (A, B, and C) are incorrect because they do not represent the specific location where the vacuum drag line is connected to remove non-condensable gases from the main condenser.
