1.	What is the advantage of stocking the coal in huge heaps?(a) Prevents from coal being oxidized(b) Provides grip for the storage(c) Prevents air circulation in the interior of heap(d) The moisture content will be eliminatedThe question was asked during an internship interview.Enquiry is from Fuel Handling System, Storage of Coal in chapter Steam Power Plant of Energy Engineering
Answer» Correct choice is (c) PREVENTS air circulation in the interior of heap To explain I would say: Coal is piled in HEAPS of 10 to 12m height on a concrete floor, by compacting it in the layers of 20 to 30cm thickness using bulldozers. This prevents air circulation in the interior of the heap. The heap top is given a gentle slope to drain off rain WATER IMMEDIATELY without WASHING the coal.
