Sep 17 2019 Many different types of mitigation are employed to remove or reduce sulfurous emissions before and after combustion in power plants. Most coals are cleaned at preparation plants a process called beneficiation or preparation prior to combustion to lower the sulfur content of coal before it is sent to a power plant. At the power plant .

For example after 10 drops 84.4 of coal grains of type 33 89.8 of coal grains of type 34 and as much as 96.9 of coal grains of type 35 were crushed to the required size 80 mm. The maximum number of drops equal to 30 resulted in virtually complete crushing of type 33 and 34 coal grains and complete 100 crushing of type 35 coal grains.

Electrostatic Benefkiation of Coal Quarterly Report

Weighing the cup before and after allows the mass of the coal that has left the cup to be determined and thus the net charge to mass ratio can be calculated. For copper beads the charge to mass ratio was -3 pCg for freshly ground coal and -0.5 pCg one month after grinding. For copper coated iron two month old coal gave a qm of 0.08 pCg.
