Loeffler boiler classification: verify the circulation method. Statement: The Loeffler boiler is a water-tube boiler that uses forced circulation of water/steam to avoid salt deposition in evaporator tubes. Choose the correct option (True/False).

Difficulty: Easy

True
False
True only for low pressures
False; it is fire-tube and natural circulation

Correct Answer: True

Explanation:

Concept
The Loeffler boiler is a high-pressure water-tube boiler employing forced circulation. It superheats steam and uses a portion of that superheated steam to evaporate/feed the water externally, thereby preventing salt deposition in the main evaporator tubes.

Final Answer
True
