Abstract: PURPOSE: An apparatus for feeding hydraulic oil of a coal pulverizer is provided to prevent performance degradation of a coal pulverizer by reducing impurities included in hydraulic oil supplied to a main tank or the coal pulverizer. CONSTITUTION: An apparatus for feeding hydraulic oil of a coal pulverizer comprises a main tank(2), a first pump(20), first filters(21a,21b), a drain line(10), a sight glass(4), an auxiliary tank(3), a second pump(30), and second filters(31a,31b). The main tank stores hydraulic oil. The first pump supplies the hydraulic oil in the main tank to a coal pulverizer through a hydraulic line. The first filters filter the hydraulic oil supplied through the first pump. The hydraulic oil supplied to the coal pulverizer is discharged through a drain line. The sight glass is arranged in the hydraulic line or the drain line. The auxiliary tank stores the hydraulic oil discharged to the drain line. The second pump supplies the hydraulic oil in the auxiliary tank to the main tank. The second filters filter the hydraulic oil supplied through the second pump.
