thermal coal for power generation and coking coal (for metallurgical coke production). International trade in thermal coals has also maintained high growth, and accounts for an average 17% of global supplies. In 2011, 6 Gt/y of the Gt/y of total production was used for power (and some steam/heat) generation (IEA, 2012).
Unlike the mechanical gravimetric feeder which acts to vary the height of coal in response to density changes to maintain a preestablished weight of coal on the weigh span, the electronic weighing feeder measures the actual density of coal and varies the belt speed to match actual with demanded combustion control delivery requirements.
These instruments calculate a substance''s total weight, using that value to determine how much coal to feed. Substituting a gravimetric feeder with a volumetric equivalent isn''t feasible for power plants. Machinery that burns coal to produce a specific amount of .
