The advantage of a counter flow fuel oil heater, as compared to a parallel flow fuel oil heater, is that the counter flow heater _______________.
AI Explanation
The correct answer is D) produces a higher oil temperature at any given steam temperature.
In a counter-flow fuel oil heater, the hot steam and the cold fuel oil flow in opposite directions, allowing for more efficient heat transfer. This results in the fuel oil reaching a higher temperature at any given steam temperature compared to a parallel-flow heater, where the steam and fuel oil flow in the same direction.
The other options are incorrect because:
A) While a larger heat transfer area can improve efficiency, it is not the primary advantage of a counter-flow heater.
B) Both counter-flow and parallel-flow heaters can be susceptible to coking if overheated.
C) Tube wall thickness is not the main factor that determines the heat transfer efficiency of the heater.
