GASIFICATION FURNACE, GASIFICATION POWER PLANT, AND METHOD OF PREVENTING BLOCKAGE OF SLAG HOLE IN GASIFICATION FURNANCE
Abstract:
An object is to prevent blockage of a slag hole with char and slag, enabling stable operation of a gasification furnace. In a configuration in which a heat exchanger (20) is provided above a coal gasification portion (10), the diameters (D1, D3) of the slag hole (16) and the throat portion (17) are set to three times or more the pitch (ST) of rows of heat exchange tubes (21). By doing so, blockage of the slag hole (16) or the throat portion (17) with char and a sintered material (50) falling from the heat exchanger (20) is prevented, enabling stable operation of a coal gasification furnace (101).
Abstract(Chinese):

一个目的是防止炉渣孔堵塞炭灰和炉渣，使气化炉稳定运行。 在煤气化部（10）的上方设置有热交换器（20）的结构中，炉渣孔（16）和喉部（17）的直径（D1，D3）设定为三倍以上 热交换管排（21）的间距（ST）。 通过这样做，能够防止从炭化热交换器（20）落下的炉渣孔（16）或喉部（17）的堵塞和烧结材料（50）的落下，能够使煤气化炉（101）稳定运转， 。
