Boiler pressure is the key factor for determining the need for a condensate polishing system. With a steam generator plant with low steam pressures (below 40 kg/cm 2), the requirement of the CPU is usually avoided.Hard scale formation and boiler metal corrosion can easily be prevented through FW treatment before sending to the boiler proper.
Coal is usually received on railroad cars or barges. Conveyor belts transfer the coal as needed to mixing bins where the various types of coal are stored. The coal is transferred from the mixing bins to the coal crusher where it is pulverized to a preselected size between 0.15 and 3.2 mm (0.006 and 0.13 in.).
