Verfahren und Vorrichtung zur Vergasung von Vergasungsbrennstoff

摘要

An object of the invention is to enhance gasification efficiency of flammable solid content when high fuel ratio fuel having fixed carbon content in large quantity is to be gasified. A material downcomer 11 for introduction of bed material 10 separated in a material separator 9 and a fuel supply port 21 for introduction of gasification fuel 12 are arranged at one side of a gasification furnace 2; a solid content supply port 19 for supply of flammable solid content 18 and the bed material 10 in the gasification furnace 2 to the combustion furnace 1 is arranged at the other side of the gasification furnace 2. In the gasification furnace 2 and between the one and the other sides of the furnace 2, vertical partition plates 22 are arranged to provide a zigzag curved flow passage 23 with upper and lower turns.
