Coal Quantity. Since coal has a heat value of 20,000 kJ/kg, for producing one we require (10765 / 20000) kg of coal. This translates to ( x 100 x 1,000) 53800 kg/hr ( T/hr) of coal for an output of 100 MW. Coal Cost. Basic cost of coal depends on the market conditions.
Cold Air Locking at Mill Inlet: This is very important for coal mill, as ambient air throttling the drying capacity of mill as well as increases the oxygen content of kiln gases making it riskier. Oxygen percentage of more than 1214% is considered catalyst for fire/explosion risk.

For example, if the tube mill runs at 100 feet per minute (FPM) (30 meters per minute [MPM]) and it requires four minutes to complete the end joining operation, 400 feet (122 meters) of strip will be used by the mill while end joining occurs. The accumulator must therefore have a capacity of at least 400 feet (122 meters). A tower can also be used.
