<p>PROBLEM TO BE SOLVED: To widen a variety of carbonaceous solid fuels applicable for a gasification furnace protected from a high temperature load by forming a protective film of molten slag on a wall in the furnace.SOLUTION: A gasification system includes a gasification furnace 10 for generating flammable gas by reacting powdered coal with an oxidizer in the furnace, a powdered coal-feeding device FS for feeding the powdered coal into the gasification furnace 10, a char-separating and recovering device 30 for separating and removing the char contained in the flammable gas generated in the gasification furnace 10, a slug-recovering part 40 for recovering and storing discharged slug after water granulation discharged from the gasification furnace 10, a char-feeding flow path 50 for feeding the char recovered by the char-separating and recovering device 30 to the gasification furnace 10, and a slug-feeding flow path 60 for feeding the discharged slug from the slug-recovering part 40 to the char recovered by the char-separating and recovering device 30 to mix them.</p> |
