Title:
DISK-SHAPED MHD GENERATOR
Document Type and Number:
Japanese Patent JPH08223902
Kind Code:
A
Abstract:

PURPOSE: To obtain a disk-shaped MHD generator which prevents a ceramic insulating wall from being cracked due to a thermal stress by a method wherein a torus-shaped electrode on the side of a discharge dust is formed so as to be divided in the circumferential direction.

CONSTITUTION: Ceramic insulating walls 6 are interposed between a torus-shaped electrode 4 and a torus-shaped electrode 5, and edges of every insulating wall 6 are tapered. The torus-shaped electrode 5 is divided into a plurality of parts in the circumferential direction in dividing parts 5a. The electrode 5 is moved in the radial direction due to the slip of a mounting bolt for the electrode with reference to the expansion in the radial direction of every ceramic insulating wall 6 so as to absorb a thermal stress, and a thermal stress due to thermal expansion is not generated. Consequently, it is possible to prevent ceramic insulating walls from being cracked due to the thermal stress.
