ABRASION RESISTANT PLATE

摘要

PROBLEM TO BE SOLVED: To improve reliability by preventing the wearing of a refractory body applied to an inner face of an introduction port 7 for introduction of a solid matter into a combustion chamber.SOLUTION: A wear resistant plate 14 is installed onto a downside inner peripheral face 7a of an introduction port 7 to cover a refractory body 6 on the downside inner peripheral face 7a of the introduction port 7 with the wear resistant plate 14. A solid matter conveyed by a screw conveyor 8 contacts to the wear resistant plate 14, so the refractory body 6 is protected. Consequently, the refractory body 6 on the downside inner peripheral face 7a of the introduction port 7 is prevented from being worn.
