Question 37Steam Plants - Assistant Engineer70% to pass
In a marine condenser designed with a reheating hotwell, the hotwell is reheated by _______________.
AI Explanation
The correct answer is D) steam lanes in the condenser.
In a marine condenser with a reheating hotwell, the hotwell is reheated by steam lanes within the condenser itself. These steam lanes allow a portion of the steam from the turbine or engine exhaust to be redirected and used to heat the condensate in the hotwell, increasing the temperature of the condensate before it is returned to the boiler.
The other options are incorrect because they do not accurately describe how the hotwell is reheated in this type of condenser design. Recirculation of condensate (A) would not provide the necessary heat, and the use of submerged heating coils (B) or a branch line from the air ejector steam supply (C) are not the primary means of reheating the hotwell in this particular condenser configuration.
