Abstract
Official abstract text for this publication.
A slag discharge system that includes: a gasification furnace which thermally decomposes and gasifies a pulverized raw material composed of a carbonaceous solid; a slag hopper which is provided at a bottom portion of the gasification furnace and receives slag produced from the pulverized raw material and in which cooling water is stored; a lock hopper which temporarily stores the slag outside of the gasification furnace; and a slag discharge line which makes the slag hopper communicate with the lock hopper. The lock hopper is disposed to the side of the gasification furnace, and the slag discharge system is provided with a water flow forming apparatus for forming a flow of the cooling water which allows the slag to be led to the lock hopper in the slag discharge line.
