Which system is noisy out of all the following ash handling systems?(a

1.	Which system is noisy out of all the following ash handling systems?(a) Steam jet ash handling system(b) Mechanical ash handling system(c) Pneumatic ash handling system(d) Hydraulic ash handling systemI have been asked this question in final exam.The above asked question is from Cool and Ash Handling System in division Steam Power Plant of Energy Engineering
Answer» Correct option is (c) Pneumatic ash handling system The explanation: The air is made to pass at very high PRESSURE in order to carry out the ash for long distance. Since the air is MOVING at high speed at high velocity in the conveying pipes, it tends to create a lot of NOISE by hitting the walls of pipe at swift turns and CURVES.
