COAL GASIFICATION FURNACE
Document Type and Number:
Japanese Patent JP2552806
Kind Code:
B2
Abstract:
PURPOSE: To provide a spouted bed gasification furnace stably operable over a long period and capable of remarkably prolonging a single operation life or operation period.
CONSTITUTION: Coal is reacted with a gasifying agent such as oxygen at a high temperature, the gasified component is discharged through an exhaustion port 2 and coal ash is dropped through a slag tap 3 into a slag cooling chamber 6 as molten slag. In a coal gasification furnace having the above operation procedure, a part or total of the members used at a part exposed to the atmosphere in the gasification chamber, e.g. a slag tap member 3 or the protection tube 5a of an optionally arranged thermocouple 5 are essentially formed with Ir or coated with Ir. An Ir alloy may be used provided that the alloy is durable to the temperature in the furnace.
