Blending of coals to meet power station requirements
In Korea, most of the coal plants are designed to fire bituminous coal with a moisture content of 2.010% as it has a high ignitability, high combustibility and high calorific value. However, due to coal import ' instability', low rank coals from Indonesia with moisture contents of up to 25% have been used.

Q&A Size of coal bin | Hearth Forums Home
Nov 17, 2007· Thank you again. Answer: ard coal has little chance of igniting from any source of combustion nearby, so I would not worry about this. Coal takes up approx 40 cubic feet per ton, so a 4x4x4 would only hold about 1 1/2 tons. As far as construction, plywood or boards placed on upright 2x4 studs makes for a fine bin.
