煤气化炉用煤粉供给系统
摘要：
本发明提供一种能够削减惰性气体的消耗量（使用量）的煤气化炉用煤粉供给系统。具备：煤粉供给料斗（3），其接纳由煤粉机（1）粉碎后的煤粉；第一加压罐（31），其在所述煤粉供给料斗（3）接纳所述煤粉时，暂时回收填充于所述煤粉供给料斗（3）的内部的惰性气体的一部分，并将该回收到的惰性气体向内部为大气压状态的所述煤粉供给料斗（3）供给；及第二加压罐（32），其填充具有使所述煤粉供给料斗（3）的内部压力上升至规定压力所需的压力的惰性气体。
摘要（英）：

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.
