(b) 22 tonnes/hour

(c) 50 tonnes/hour

(d) 10 tonnes/hour

This question was addressed to me in an international level competition.

I would like to ask this question from Cool and Ash Handling System in division Steam Power Plant of Energy Engineering

Answer 1

Correct answer is (c) 50 tonnes/hour

The best explanation: The capacity of low pressure hydraulic ash handling system is 50tonnes/hour at a speed of 3m/s. Since the ash produced is mixed in water and dumped, the water has the ability to dissolve and intake more amount of ash. And this mixture is spread throughout the sump.
