摘要

To provide the gasification furnace facility capable of suppressing wear of a gasification furnace wall and a structure caused by a flow of the product gas.SOLUTION: The gasification furnace facility comprises: a gasification furnace wall 111 having a cylindrical shape through which the product gas gasified in a gasification furnace for gasifying pulverized coal flows, and a product gas pipe 80 for guiding the product gas to the outside of the gasification furnace wall 111. An upstream end 80a of the product gas pipe 80 protrudes from the gasification furnace wall 111 to the inside. The upstream end 80a of the product gas pipe 80 has a diameter-expanded part 80b having a bell mouth shape that is expanded toward the inside of the gasification furnace wall 111.SELECTED DRAWING: Figure 3
