Online coal flow measurement. The EUcoalflow microwavebased technology has been successfully applied to coal flow pipes after mills for mass flow monitoring and are used as basis for improvement of coal flow distribution.
Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% value is exceeded. Values .

The efficiency was computed as the ratio of energy generated (from MW data in Table 6) to energy burned (computed from pulverized coal data, Table 2, and coal mass flow data, Table 6). The plot, which includes data from the two tests from [ 9 ], shows a negligible correlation between PSD and efficiency.
