Title:
STICKING MATTER REMOVING DEVICE FOR HIGH TEMPERATURE GAS COOLING SYSTEM
Document Type and Number:
Japanese Patent JP3899990
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a sticking matter removing device for a high temperature gas cooling system, wherein the service life of a scratching-off member of a sticking matter is remarkably lengthened more than the conventional service life, and the sticking matter in the high temperature gas cooling system is smoothly and stably removed.
SOLUTION: This sticking matter removing device of the high temperature gas cooling system has the scratching-off member arranged in the high temperature gas cooling system arranged in a flue for passing high temperature gas from a high temperature processing furnace of waste, and scraping off the sticking matter by contacting with the sticking matter of an inner wall, a cylindrical support member for supporting this member, a lifting means, and a waiting room of the scratching-off member and the support member. The knife edge is arranged along the inner wall inner periphery of the waiting room by setting clearance with the support member to 15 mm or less. In this case, a construction material of the scratching-off member is further desirably formed of a Co group heat resistant alloy.
