GASIFICATION FURNACE PROVIDED WITH TEMPERATURE MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress adhesion of slug to a temperature detector in a gasification furnace gasifying a finely powdered solid carbonic material such as coal. SOLUTION: A temperature measurement device 9 placed by penetrating the furnace wall 39 of the gasification furnace gasifying finely powdered solid carbonic material such as coal where molten slug 53 of raw material ash adheres or flows down, has a rod shape temperature detector 19, an inner cylinder 21 in which the rod shape temperature detector 19 is inserted and an outer cylinder 12 capped from the furnace inner side tip end of the inner cylinder 21 to a certain length part. The furnace inside tip end of the cylinder 21 is opened. The other end is made a support part supporting air-tightly the temperature detector 19. Both ends of the outer cylinder 23 is sealed and cooling fluid is sent into the space between the inner cylinder and the outer cylinder and let flow from an inlet 27 to an outlet 29. Inert gas or a part of the produced gas is sent from an inlet 31 at the back end side of the inner cylinder 21 and let discharge toward the furnace inside out of the tip end opening of the inner cylinder 21 so that adhesion of slug to the temperature detector 19 is suppressed.
