AManually operated with a hand wheel.
BAir operated with a pneumatic motor.
CManually operated with a hand-crank.
DManually operated with an endless chain.
AI Explanation
The correct answer is D) Manually operated with an endless chain. The soot blower element is rotated manually using an endless chain mechanism, as shown in the illustrated diagram SG-0023. This type of manual operation is a common design for soot blowers used on marine boilers and steam generators. The other options are incorrect because: A) A hand wheel would not provide the necessary rotational force to turn the soot blower element. B) A pneumatic motor would require an air supply system, which is not indicated in the diagram. C) A hand crank would not be able to continuously rotate the soot blower element like an endless chain.
