FINE COAL POWDER SUPPLY SYSTEM FOR COAL GASIFICATION FURNACE

摘要

The purpose of the present invention is to provide a fine coal powder supply system for a coal gasification furnace, which enables the reduction in the amount of an inert gas consumed (used). The fine coal powder supply system comprises: a fine coal powder supply hopper (3) which receives a fine coal powder that is pulverized using a coal pulverization machine (1); a first pressurized tank (31) which temporarily collects a portion of an inert gas that is filled in the fine coal powder supply hopper (3) and supplies the collected portion of the inert gas to the fine coal powder supply hopper (3) of which the inside is put into an atmospheric state during the reception of the fine coal powder by the fine coal powder supply hopper (3); and a second pressurized tank (32) which has, filled therein, an inert gas having a pressure required for increasing the pressure of the inside of the fine coal powder supply hopper (3) to a predetermined pressure.
