1.	Which system consumes less power out of all ash handling systems?(a) Mechanical ash handling system(b) Pneumatic ash handling system(c) Hydraulic ash handling system(d) Steam jet ash handling systemI have been asked this question in unit test.This intriguing question originated from Cool and Ash Handling System topic in section Steam Power Plant of Energy Engineering
Answer» Correct answer is (a) Mechanical ash handling system Explanation: The mechanical ash handling system consumes less amount of power. Since the power is REQUIRED by the conveyor belt to transfer the ash from boiler furnace to over HEAD bunker which is located at END of the conveyor belt.And in case of pneumatic there is high power requirement to draw and blow the air at high velocities and high pressures.
