PROBLEM TO BE SOLVED: To provide a pulverized coal supply system, an operation method thereof, and a coal gasification power generation facility that can reuse pressurized gas for transfer of pulverized coal.SOLUTION: A pulverized coal supply system comprises: a first pulverized coal hopper; a pressurized gas collection line connected to the first pulverized coal hopper; and a pressure filter provided in the pressurized gas collection line to remove pulverized coal in pressurized gas collected from the first pulverized coal hopper. The pressurized gas collection line is connected to at least one of a buffer tank located on the downstream side of the pressure filter to store the pressurized gas collected from the first pulverized coal hopper or a second pulverized coal hopper provided in parallel with the first pulverized coal hopper.SELECTED DRAWING: Figure 2 【課題】微粉炭搬送用の加圧ガスの再利用が可能な微粉炭供給システム及びにその運転方法並びに石炭ガス化発電設備を提供する。【解決手段】微粉炭供給システムは、第１微粉炭供給ホッパと、前記第１微粉炭供給ホッパに接続された加圧ガス回収ラインと、前記加圧ガス回収ラインに設けられ、前記第１微粉炭供給ホッパから回収された前記加圧ガス中の微粉炭を除去するための加圧フィルタと、を備え、前記加圧ガス回収ラインは、前記加圧フィルタの下流側に位置し、前記第１微粉炭供給ホッパから回収された前記加圧ガスを貯留するためのバッファタンク、又は、前記第１微粉炭供給ホッパに対して並列に設けられた第２微粉炭供給ホッパの少なくとも一方に接続されている。【選択図】 図２
