PURPOSE: A pulverized coal supplying apparatus is provided to supply the constant quantity of pulverized coal to a combustion chamber continually. CONSTITUTION: A pulverized coal supplying apparatus comprises a pulverized coal tank(110), a pulverized coal feeding unit(120), a pulverized coal transfer pipe(140), a vent unit(144), a disc(160), an air channel opening(150), and a drive unit(170). In the pulverized coal tank, the pulverized coal is stored. The pulverized coal feeding unit supplies the pulverized coal to the pulverized coal tank. The pulverized coal transfer pipe passes through the pulverized coal tank and the one end of the pulverized coal transfer pipe is connected to the combustion chamber. The vent unit supplies the air in the direction in which the pulverized coal is transferred. The vent unit is connected to the one end of the pulverized coal transfer pipe to cause the airflow inside the pulverized coal transfer pipe. The disc is arranged inside the pulverized coal tank to be rotated. A plurality of filling holes is formed in the end part of the disc along the columnar direction. The air channel opening is formed in a pulverized coal transfer pipe area positioned inside the pulverized coal tank. The drive unit rotates the disc.
