PURPOSE: An apparatus for pneumatically transporting powdered coal at a high pressure is provided to stably feed a constant amount of powdered coal by constantly maintaining the pressure of an injection container at a set value. CONSTITUTION: An apparatus for pneumatically transporting powdered coal at a high pressure comprises an injection container(110), a charging container(120), first and second transfer gas feeding devices(112,122), first and second load cells(114,124), a pressure maintaining unit, a powered coal transferring unit, and a powered coal breezing unit. The injection container feeds powdered coal to a high pressure reactor at a high pressure. If a constant amount of the powdered coal is transferred from the injection container, the charging container recharges the powdered coal to the injection container. The first and second transfer gas feeding devices feed transfer gas to the injection container and the charging container. The first and second load cells measure the weight of the injection container and the charging container. The pressure maintaining unit constantly maintains the internal pressure of the injection container. The powered coal transferring unit transfers the powdered coal in the injection container to the high pressure reactor by the differential pressure of the injection container and the high pressure reactor.
